Note Reference iii iv Introduction The TT was a revolutionary car design when it was first unveiled in 1995. It’s strictly geometrical, formally coherent design language made it an icon with huge charisma. For the third TT generation, the Audi designers have returned to many of these ideas and placed them in a new context that is as dynamic as it is diverse. The third generation of the compact sports car again commands attention with its emotional design and dynamic attributes. Standout features of the new coupe are its innovative driveline technology as well as its new operating and display concept. The central motif was the circle – embodied in the curves of the roof line, and the front and the rear overhangs with their resolutely horizontal lines. From the side, many details of the new Audi TT are reminiscent of the firstgeneration classic in many respects. 630_002 1 Model history for the World-wide market In 1995 Audi presented a pioneering study: the Audi TT. The Coupe (IAA Frankfurt, 1995) and Roadster (Tokyo Motor Show, 1995) showcars were followed by the production versions of the Audi TT Coupe in 1998 and Audi TT Roadster in 1999. When the first-generation Audi TT came on the market in 1998 it was a design revolution. Radical in design, but suitable for everyday use – that was the motto for the first Audi TT. 2007 A new edition of the Roadster also went into production a year after the Coupe. The third generation of this classic has adopted many of the design elements that characterized the first-generation TT – coupled with innovative technology. Between the first and third generation of the TT lie nearly 20 years of development in technology and design. Here, in brief, are the key milestones in the model history of the Audi TT. 2000 – 2003 The TT-R racing car prototype provided the basis for the successful reentry of Audi into the German Touring Car Championship (DTM). 1998 Start of production of the Audi TT Coupe in Ingolstadt and Győr. 2006 The second generation of the Audi TT (Type 8J) is rolled out featuring a new design and new technology. 1999 Start of production of the Audi TT Roadster in Ingolstadt and Győr. Find out more about the model history of the Audi TT. 1995 Presentation of the Audi TT study as a Coupe at the IAA in Frankfurt. 2 2010 The second generation of the TT makes a successful entry into motor racing, in the Long Distance Championship. 2012 Audi reveals the Audi TT RS plus, the most powerful version of the sports car, powered by a 5-cylinder TFSI engine. 2008 Audi presents the Audi TT clubsport quattro study with shorter windscreen and sporty attachments. 2014 The allroad shooting brake study provides a glimpse into the design of the new Audi TT. 2014 The third generation of the Audi TT is released – first as a Coupe and shortly afterwards as a TTS in Europe. 630_035 3 The 2016 Audi TT has many features which are explained in detail in this Self-Study Program. Here is a quick summary: Engine Assistance systems 4-cylinder engines with turbocharger : • 2.0L TFSI • Horsepower: 220 hp (162 kW) @ 4500 - 6200 rpm • Torque: 258 lb ft (350 Nm) @ 1600 - 4400 rpm The following systems are optionally available: • Audi side assist • Park assist system with ambient display Air conditioning All control functions are integrated into the air vents. The automatic air conditioning system has small displays which show the selected setting. 4 Body Power transmission Audi Space Frame (ASF) body made from aluminum and steel with highstrength and ultra-high-strength steel alloys, die-cast aluminum nodal elements and side panels as well as a roof made of aluminum. Full-time quattro drive – systematically developed and refined for the TT – with electro-hydraulic multiplate clutch on the rear axle. It is possible to customize the all-wheel drive characteristics by networking the quattro drive with Audi drive select. 630_007 Displays and operation Suspension Fully digital Audi virtual cockpit instrument cluster with dynamic animations and graphics.

The bodyshell of the 3rd generation uses components of the Modular Transverse Platform (MQB) At 99 in (2505 mm), the TT has the shortest wheelbase of any vehicle in the MQB concept. The substructure is formed from the cross members, sections of the A-pillars, the bulkhead, floor pan, rear wheel arches and the rear tail panel. The hot-formed steel in the sub-structure weighs 87 lb (39.5 kg) and accounts for almost a quarter of the total structural weight. Prior to forming, the steel is heated to approximately 1832 °F (1000 °C). It is then cooled immediately to about 392 °F (200 °C) in a water cooled pressing tool during the forming process. This drastic change in temperature produces an extremely strong iron-carbon micro-structure. The form-hardened steel has a relatively low wall thickness and is correspondingly light. Advanced high strength, cold-formed steel components together with extruded aluminum sections for the outer sills and aluminum panels for the rear wheel arches complete the sub-structure of the Audi TT. Body sub-structure 630_074 Sub-structure integrated into the MQB platform Torsional rigidity Compared to the predecessor model, the hybrid ASF of the new TT has a 23% higher static torsional rigidity while retaining a high level of dynamic rigidity. Key: Sheet aluminum Die-cast aluminum Aluminum section Ultra-high strength steel (hot-formed) Advanced high strength steel High strength steel Low strength steel 8 Find out more about the bodyshell of the Audi TT. The occupant cell, which weighs only 149 lb (68 kg), is an aluminum lattice with four castings that form the nodal elements of the body shell. Large nodal sections of the A-pillars connect the side roof frame profile, sill, window cross member and the upper longitudinal section at the front end. Two smaller cast nodal elements above the rear window connect the roof arch to the flat C-pillars and the rear roof cross member. The entire outer skin of the Audi TT is made from aluminum: • • • • Front fenders. Sidewalls. Roof. Attachments: hood, doors and trunk lid. In total, the complete bodyshell with attachments weighs approximately 608 lb (276 kg). 630_012 9 Joining technology The key to optimizing the body structure is using "the right materials in the right place". The resulting challenge for the joining technology was to develop universal and reliable solutions for the large variance in material/thickness combinations in the body. On the TT, Audi uses "cold" joining techniques such as riveting, flow-drill screwing and clinching to create the aluminum/steel hybrid structure. Adhesive is also used to strengthen the connection and to prevent contact corrosion of the aluminum/steel joint. The body is constructed using the following types of joining methods: • • • • • • 3020 spot welds. 1113 punch rivets. 44 solid punch rivets. 128 flow-drill screws. 199 clinching points. 6 ft (1.9 m) of MIG/MAG welds (metal inert gas/metal active gas). • 16.07 ft (4.9 m) of laser-welded seams. • 249 ft (76 m) of adhesive. Joining methods used on the Audi TT Bonding Laser welding Semi-tubular punch riveting Resistance spot welding 10 Safety precautions against contact corrosion Aluminum has a naturally occurring (passivating) surface oxide layer that protects the underlying material from corrosion. This is why an unpainted aluminum component does not normally corrode. However, if aluminum comes into contact with a metal which has a positive electrical potential relative to aluminum and is in an electrolyte, such as salt water, contact corrosion will occur. The greater the difference in electrical potential, the greater the corrosion will be. Since aluminum is usually the less noble metal, it is degraded. Contact corrosion can also occur if unsuitable connecting elements (screws, nuts, washers, etc.) are used. Therefore, a number of precautions must be taken in order to prevent this process from occurring during body production and repair work. Audi uses only connecting elements with a special surface coating for the aluminum/steel hybrid construction used in the TT. In addition, all rubber and plastic parts and all adhesives are made of non-conductive materials. As a further precaution, all hybrid metal connections are sealed with polyvinyl chloride (PVC) or with wax after cataphoretic dip primer coating. The cataphoretic coating (sometimes referred to as E-coat) is an electrically induced surface treatment that provides resistance to corrosion and oxidation. See the complete definition on the following page. Solid punch riveting Clinching MIG/MAG welding Flow-drill screwing 630_075 11 Thermal "hot" and mechanical "cold" joining techniques The choice of the right joining technique in modern body construction is material-dependent. Welding similar materials is still the most frequently used joining technique. These welding and soldering techniques are called "hot" joining techniques and have a large variety of applications. However, the heat input causes high internal stresses in the component, which often can only be compensated through time-consuming re-work. The mechanical "cold" joining technique has the decisive advantage over the thermal joining technique in that hybrid joints can be reliably produced between different types of materials. The positive properties of the material are not adversely affected by thermal influences. "Hot" joining technique in the Audi TT MIG/MAG welding With the MIG/MAG (MIG = metal insert gas, MAG = metal active gas) welding technique, an electric arc forms between the automatically fed welding wire (electrode) and the workpiece. A shielding gas protects the electric arc and the welded surface against the ingress of ambient air. The inert gas and welding wire have to be adapted to the basic material. The following "cold" joining techniques are used: • Punch riveting. • Clinching. • Flow-drill screwing. • Seaming. • Bonding. It makes good sense to combine the mechanical spot joining techniques with bonding methods. First, it increases the strength of the joint and, second, the adhesive also acts as insulation in the case of hybrid aluminum/steel joints. This, in combination with seam sealing, prevents direct contact between the metals and ensures that corrosion cannot occur. In addition, a carefully selected adhesive concept also helps to absorb the differing degrees of thermal expansion of the individual materials. Cataphoresis is a fully automated process of painting by immersion, which is based on the movement of charged particles in an electric field (paint) towards an oppositely charged pole (metallic surface to be painted). The main objective of the coating process is to protect the surfaces from corrosion, and its properties make it the ideal treatment for this purpose. This technique also allows areas which are hard to reach, such as recessed areas, piping etc to be painted. Advantages: • Versatility in use. • High weld seam strength. • Outstanding thin panel properties. 630_076 Resistance spot welding In the case of resistance spot welding, panels are welded together using opposed electrodes under the application of force, pressure and electrical current. Advantages: • No additional connecting element. • No heat influence zone. • Short welding time. Laser welding 630_077 With laser welding, the focused laser beam serves as an energy source. In the welding head, the laser beam is focused by a lens and reflected back onto the workpiece by mirrors. At the point of contact, the laser beam melts the workpiece. Welding can be performed both with and without welding filler material. Advantages: • Less influence of heat. • Less thermal distortion. • Less time spent on re-work. 630_065 12 "Cold" joining technique in the Audi TT Punch riveting Punch welding is a method where pieces that have not been pre-punched are joined together by inserting a rivet (semi-tubular rivet or solid punch rivet) into two or more layers of the workpiece, the rivet piercing the upper workpiece layers and then expanding in the lower workpiece layer. Semi-tubular punch rivet Solid punch rivet 630_061 Advantages: • • • • No pre-punching needed. High dynamic strength. Form-fitting and non-positive connection. Ideal for hybrid joining. 630_062 Clinching With clinching, panels or sections are joined together by cold-forming the materials to produce a form-fitting and non-positive connection without the need for an auxiliary joining element such as a rivet. In this case, the connections can have two or more layers. Advantages: • No additional connecting element. • Protects the surfaces of coated workpieces. 630_063 Flow-drill screwing A special, coated screw is inserted through partially nonpre-punched workpieces by applying high contact pressure. Due to the high pressure and high RPM, the screw forms a thermoflow hole without producing a burr. The screw penetrates the material and, in the process, cuts its own thread. Advantages: • High strength through thermo-flow process. • Ideal for applications in which the material is accessible on one side only. • Easy to disconnect. 630_064 Bonding In addition to punch riveting, clinching, solid punch riveting, flow-drill screwing and resistance spot welding, additional adhesive bonds are used in certain areas. These bonds increase the strength of the connection. Adhesive is also used in seamed connections, as is the case at the rear wheel arch. In other areas of the bodyshell, use is made of adhesive beads to provide sealing and insulation between aluminum and steel, as well as for noise reduction. Advantages: • • • • Large area connections are possible. Unchanged surface and micro-structure. Suitable for connecting different materials. Sealing connection. 630_078 13 Fuel Filler Filler flap module The new TT is the first Audi model to eliminate the fuel filler cap. The fuel filling nozzle slots directly into the filler neck. Two flaps are pushed to the side when the nozzle enters the filler neck and seal the neck after refueling has been completed. The fuel filler flap is opened by lightly tapping on the embossed TT logo. The flap is locked and unlocked automatically when the central locking system is actuated. 630_080 14 Rear spoiler The Audi TT has an electrically retractable rear spoiler as standard. There is a choice of 2 operating modes for extending and retracting the rear spoiler. Driving stability is increased significantly at high speeds when the rear spoiler is extended. Operating mode Function Automatic mode Automatic extension and retraction: The rear spioler is automatically extended when a speed of approximately 75 mph (120 km/h) is exceeded and retracted again at about 50 mph (80 km/h). Manual mode Manual extension: The rear spoiler can be extended fully with a short touch of the rear spoiler button in the center console. Manual retraction: • At a speed of up to about 12 mph (20 km/h), the rear spoiler can be retracted by holding the button down. • At a speed of between 12 mph (20 km/h) and 75 mph (120 km/h), the rear spoiler can be retracted fully by touching the button. Sheet-metal spoiler blade Drive unit with drive shaft and pivot mechanism (hinge) Trunk lid 630_081 15 Passive safety Components Depending on country version and trim level, the passive occupant protection system in the Audi TT may have the following components and systems: • • • • • • • • Airbag Control Module. Driver airbag. Front passenger airbag. Front side airbags. Head airbags. Knee airbag, driver and front passenger sides. Front airbag crash sensors (acceleration sensors). Front crash sensors for side crash detection (pressure sensors). • Rear crash sensor for side crash detection (acceleration sensor). • Front inertia-reel seat belts with pyrotechnic belt tensioners. • Inertia-reel safety belts with active belt force limiters. • Rear inertia-reel safety belts with pyrotechnic belt tensioners, driver and front passenger sides. • Safety belt warning for all seats. • Safety belt switches on all seats in the safety belt buckles. • Seat occupancy sensor in front passenger seat. • Airbag disabling switch, front passenger side. • Front passenger airbag OFF and ON warning lamps. • Driver and front passenger seat position sensors. • Battery disconnect. Front Passenger Airbag -disabled- Indicator lamp A new front passenger airbag OFF warning lamp is used on the 2016 TT. It is integrated into the interior light module. The new warning lamp now indicates when the airbag is ON as well as OFF. ON warning lamp 630_042 Text indicating the status of the front passenger airbag 16 OFF warning lamp Driver airbag Knee airbag 630_013 17 Front passenger airbag Side airbag Knee airbag Side curtain airbag, driver and front passenger side Side curtain airbag The Audi TT is equipped with side curtain airbags for the first time. The limited installation space resulting from the shape of the bodyshell presented a number of engineering challenges. Side airbag Despite the lack of installation space and the absence of a B-pillar, the Audi TT meets the 2013 US statutory requirements according to FMVSS 226 – Ejection Mitigation. Description of FMVSS 226 – Ejection Mitigation • FMVSS = Federal Motor Vehicle Safety Standards. • 226 – Ejection Mitigation = the protection of vehicle occupants from ejection through the side windows, particularly in a rollover accident. Side airbag The side airbag in the Audi TT is designed as a thorax-pelvis airbag, and not as a head-thorax airbag. Head airbags and head-thorax airbags would obstruct each other if installed together and thus be less effective in protecting the vehicle occupants. Side curtain airbag attachment Due to the requirements of FMVSS 226 – Ejection Mitigation and the absence of a B-pillar, the side curtain in the Audi TT is attached by self-tapping screws. Left-hand side roof frame Attached with self-tapping screws Left-hand side curtain airbag 630_046 18 Engine Torque/power curve of 2.0l TFSI engine Engine with engine code CHHC Power output in hp (kW) Torque in lb ft (Nm) The following modifications have been made to the engine for use in the Audi TT: • Oil pan top section with 2 oil return lines. • Crankcase breather with modified fine oil separator. • Modified aluminum coolant pump.

All model versions of the 2016 Audi TT will use the 6-speed DSG S tronic transmission and Haldex coupling. Rear axle final drive unit, 5th generation Haldex coupling quattro drive The Haldex coupling software has been specially adapted for the Audi TT. The new software provides both enhanced driving dynamics and higher efficiency. Driving Profile Selection Switch Module ESC-OFF button The Haldex software now makes more intensive use of driving dynamics data measurement while closely monitoring driver input and vehicle driving status, reducing reaction time significantly. To utilize the potential of this new technology, quattro drive is coupled with Audi drive select. Audi drive select can be used to select between different vehicle configurations. A specific Haldex coupling setup is assigned to each configuration. (no start stop in the US TT) auto/comfort The Haldex coupling setup matches the known driving behavior and the quattro-typical traction of the 2015 Audi A3. In individual mode, the driver can choose a Haldex coupling setup independent of other vehicle systems. dynamic This setup provides more agile steering response. The coupling is engaged as soon as the driver steers into the corner, allowing it to react more quickly to the closing of the coupling when accelerating out of the corner. The result is a smaller decrease in torque in response to oversteer and load changes. 21 Find out more about the quattro drive of the Audi TT. 630_049 All Wheel Drive Control Module Haldex Clutch Pump Selector mechanism Selector lever cable for actuating the park lock Emergency release mechanism 630_048 Reference For more information about the 5th generation Haldex coupling and the thermal management system of the 0D9 transmission, please refer to eSelf-Study Program 990143, The 2015 Audi A3 Introduction. 22 6-speed DSG transmission - S tronic When the Audi TT is launched, the transmission will only be available with quattro drive. A front-wheel drive version will be available at a later date. Vehicles with quattro drive (all 2016 Audi TT vehicles in North America) are equipped as standard with Audi drive select. In addition to familiar transmission functions such as starter lock, selector lever lock, software shiftlock, parking lock, tiptronic mode and kick-down, this SSP explains in depth the selector mechanism, downhill assist, the launch control program and the start assist systems. Selector mechanism The selector mechanism of the transmission has been adapted to the interior of the Audi TT. The operating logic is identical to the 2015 A3. In addition to the selector lever positions "P", "R", "N", "D" and "S", it is possible to shift gear manually in tiptronic mode using the selector lever or the shift paddles on the steering wheel. The gear selected and the active gear are displayed in the Audi virtual cockpit. 630_052 The parking lock emergency release mechanism can be accessed by unclipping the selector lever cover from the center console and pushing the insulating foam to the side. 630_053 Reference For more information about the selector mechanism and the emergency release mechanism of the selector lever, please refer to eSelf-Study Program 990143, The 2015 Audi A3 Introduction. 23 Downhill assist The downhill assist functions aids the driver on downhill gradients. In selector lever positions "D" and "S", it is activated when the brake pedal is depressed or when the speed is set on the cruise control system. Downhill assist tries to maintain the reduced speed within the bounds of physical and drive limitations. The transmission selects a gear appropriate to the gradient. It may be necessary to additionally correct the vehicle’s speed with the foot brake. Given that downhill assist shifts down into no lower than 3rd gear, it is advisable to switch to tiptronic mode on very steep gradients. This allows the vehicle to be shifted manually into 2nd or 1st gear to make use of the engine braking effect and relieve the load on the brakes. Downhill assist cuts out again as soon as the gradient lessens or the accelerator pedal is pressed. Launch control program The launch control program enables maximum acceleration. Conditions: When using the launch control program, the transmission temperature will rise sharply. It is possible that the launch control program will be unavailable until the transmission has cooled sufficiently. • The engine is at operating temperature. • The wheels and the steering wheel are in the straightahead position. The launch control program puts maximum strain on parts of the drivetrain, resulting in increased wear. • The ESC-OFF button was briefly pressed once while the engine was running. • Selector lever is in the "S" position or in the tiptronic gate or dynamic mode is selected using Audi drive select. • Depress the brake pedal firmly for 1 second and hold it down. • Depress the accelerator pedal fully and hold it down. • Ease off the brake. Hill start assist systems The hill start assist systems utilize the capabilities of the ESC system and the parking brake. They assist the driver by stopping the vehicle from inadvertently rolling away. Hill start assist and integrated start assist are standard. The requirements for system operation are that the driver's door is closed, the driver's safety belt is fastened and the engine is running. Integrated start assist is effective when the parking brake is actuated. It is released at drive-away as soon as enough drive torque is available to set the vehicle in motion. Integrated start assist is only operational when the driver's safety belt is fastened. Hill start assist is available when the brake pedal is depressed and the vehicle is at a gradient of 5% or steeper. When the vehicle stops on a gradient, the current brake pressure is maintained by the ESC control valves. If the brake pedal is released in order to drive away, brake pressure is maintained for about 1.5 seconds. As soon as enough drive torque is available to move the vehicle, the brake is released. This function aids starting on gradients because the vehicle is largely prevented from rolling back. Hill start assist is also available in reverse gear. 24 Chassis Overall concept One key focus of development work on the chassis of the Audi TT was on achieving sporty driveability combined with dynamic and highly precise handling. This was achieved through a highly engineered suspension system with a front axle based on the MacPherson concept and a redesigned four-link rear axle. In keeping with the sporty setup, use is made of progressive steering as standard. Torque vectoring also makes a major contribution to excellent handling. The use of generously sized brake systems with vented brake discs at the front and the electro-mechanical parking brake at the rear underscore the sporty overall concept. 630_082 The following suspension variants are available for the Audi TT: Suspension/steering versions Features Standard suspension (1BA) The standard suspension as basic equipment features steel springs and unregulated damping. Suspension with electronic damper control (1BQ)1) This suspension has been set up specially for the Audi TTS and is standard equipment. 1) 1) Production control number 25 Axles and wheel alignment Front axle The front axle is based on the Modular Transverse Platform (MQB).

They can only be set by selecting the relevant mode in Audi drive select. Depending on preference, the driver can choose between comfortable (comfort), sporty (dynamic) and balanced (auto) damping characteristics. Depending on the degree of damping, the coils in the damper pistons are activated by the output stages of the control module by applying up to about 5 A of current (maximum damping). The damper is not permanently activated when the vehicle is stationary. Vehicle: Audi drive select comfort auto dynamic individual 68°F 630_096 System response to faults As a fully integrated system, the damper control system has self-diagnostic capability. Any detected system faults are indicated to the driver by a fault message in the instrument cluster. Depending on the nature of the fault, the system response can range from a partial shut-down to a full shut-down of the system. Damper control Fault! You can continue driving 630_103 29 Brake system Depending on the model, the 2016 TT will use 16” or 17” brake systems on the front and rear axles.Larger-diameter brake pistons are used on all models. The result is a more sporty pedal feel (short idle travel, defined bite point). The electro-mechanical parking brake (EPB) is used for the first time in the Audi TT. The brake booster and foot controls are the same as those on the 2015 A3. The TT is also equipped with the Continental ESC Mk 100 ABS/ESP system as found on the 2015 A3.

Special steering maps have been developed for the Audi TT. To ensure a high level of driving comfort, the Audi TT is equipped as standard with the progressive steering system used in the Audi A3. The mechanically adjustable steering column is also a carry-over from the Audi A3. Standard equipment consists of a newly developed three-spoke steering wheel featuring a new, sporty design. Steering wheel • Standard equipment: Three-spoke steering wheel with "Sport rim" for Audi TT 630_115 Electro-mechanical power steering • Carry-over from Audi A3 • Use of special, Audi TT specific maps • Progressive steering as standard equipment 32 Steering column • Mechanically adjustable • Height adjustment: +/- 0.98 in (25 mm) • Longitudinal adjustment: +/- 1.18 in (30 mm) • Carry-over from Audi A3 Electro-mechanical power steering (EPS) In terms of its design, functional principle and service operations, the electro-mechanical power steering system is identical to the system already implemented in the 2015 A3. 630_116 Operation Depending on whether auto, dynamic or comfort mode is selected, the system activates steering maps which provide universal, dynamic or comfort-oriented power steering. When individual mode is selected, the driver can freely select one of three maps. Vehicle: Audi drive select comfort auto dynamic individual 68°F 630_096 Progressive steering The Audi TT receives progressive steering as standard. Progressive steering is provided by a variable steering ratio using a special rack spline geometry. The steering ratio is at its highest when driving in a straight line and during minor steering inputs around the center position. Rotation of the steering wheel through an angle of about 14° produces a steering angle of about 1° at the front wheels (steering ratio of approximately 14). The ratio decreases with increasing steering angle, and thus becomes more direct. This gives the Audi TT agile and precise handling in city traffic and on windy country roads with little steering effort. This reduces amount of steering input required and gives significantly better dynamics during sporty driving maneuvers. Rack Steering pinion At large steering angles (for example, in inner-city areas or when parking), the steering ratio is reduced to significantly reduce steering effort for the driver. The diagram below clearly shows that with progressive steering, the steering wheel has to be moved much less in order to turn the front wheels to full lock. 630_109 Key: Steering ratio (-) Steering lock with progressive steering Steering lock with conventional steering Progressive steering in the Audi TT Conventional steering in the Audi A3 630_090 Pinion angle (°) Reference For more information about the electro-mechanical power steering (EPS), refer to eSelf-Study Program 960143, The 2015 Audi A3 Running Gear and Suspension System. 33 Steering wheels Newly developed steering wheels are used in the Audi TT.
