3 Service Technical Information 84/17 3995 Noise Symptom/Jerking - Clicking Noise/Rough-Running Engine/Jerking Under Load With Respect to Transfer Case: Programming all-wheel drive control unit/checking transfer case (SY 84/17) ENU Information Currently, a high percentage of warranty returned transfer cases are evaluated as "OK" during testing by the supplier. For this reason, the two previous symptom-based repair instructions are being replaced by these symptom-based repair instructions: 1. "Eliminating noise symptoms - Re-programming control unit for all-wheel drive (Creaking noise from around the transfer case/SY0416) – only relevant for vehicles from model year 2015 to 2016 and 2. "Eliminating symptoms - Engine: Replacing transfer case (Rough-running engine, vehicle jerks under load/SY2516) in Repair Group 39 - Final drive. Information The "transfer case" is designed as an active all-wheel drive system that is dynamically adapted to the respective driving state. Power transmission between the front and rear axle is controlled electronically via the "all-wheel drive servo motor (transfer case)" and the multi-plate clutches integrated in the transfer case. On all-wheel drive vehicles, the drive train can become strained at low speeds and when the steering is turned sharply when "Off-road mode" is activated, depending on design. • Under extreme conditions, the drive train can also become strained when "Off-road mode" is deactivated. • Customers with little experience with all-wheel drive vehicles can interpret this behavior as a fault, which in turn can result in incorrect diagnoses in the workshop. Vehicle Type: Cayenne (VR6 - 92A)/Cayenne S (92A)/Cayenne GTS (92A)/Cayenne Turbo (92A)/Cayenne Turbo S (92A)/Cayenne S Diesel (V8 - 92A) Model Year: As of 2011 up to 2017 Equipment: With transfer case 2017© Porsche Cars North America, Inc. AfterSales Sep 22, 2017 Page 1 of 8 3 Service 3995 With regard to 1: ENU Technical Information 84/17 1. All-wheel drive servo motor (transfer case) see "Symptom 1" below Information "Symptom 1" described below and the corresponding test procedure is relevant only for vehicles from model year 2015 to model year 2016. This procedure and remedial action must not be used for vehicles from model years 2011 to 2014. Symptom 1: Clicking noises can come from around the transfer case when driving slowly or when manoevring in a parking garage. Information The customer complaint about a clicking noise (from the servo motor) can only occur on vehicles: • produced between 6 November 2013 and 1 December 2015 and • with a software version lower than version 1010 in the all-wheel drive control unit. Cause: Clicking noises can come from around the transfer case when manoeuvring the vehicle (or driving slowly) due to activation of the transfer case servo motor. Remedial Action: Before doing any other work, the symptom must be simulated using a test procedure. (Opening the door windows can be helpful when evaluating noises). 1 Conditions for the first test procedure: • • • Activate the Start/Stop function and deactivate all sources of noise in the vehicle (Entertainment, ventilation, etc.). A multi-story parking garage can be useful for acoustic reverberation. • • • • On a straight stretch from speeds less than 10 mph (20 km/h) brake the vehicle to a standstill. The best way of finding the clicking noise is by driving slowly and then stopping the vehicle. In the event of a distinct customer complaint, the clicking noise can already be heard on a straight stretch with partial load accelerations. To correct the problem, re-program the all-wheel drive control unit. See "Procedure" section below. The measure is complete after programming the all-wheel drive control unit.

Service Technical Information With regard to 2: 84/17 ENU 3995 3 Transfer case see "Symptom 2" below Information "Symptom 2" described below and the corresponding test procedure is relevant for vehicles from model year 2011 to model year 2017. For vehicles from model year 2015, the test procedure described under "Symptom 1" must be completed before doing any other work. Symptom 2: Symptoms to be checked: • • • Rough-running engine or the vehicle vibrates or the engine jerks under load. Information Generally, the vehicle can start jerking when driving in tight corners with a small radius and when Off-road mode is activated. This behavior is perfectly normal for all-wheel drive vehicles and is not a defect on the vehicle. NOTICE Driving with connectors on chassis components or control units disconnected. • Bearings in transfer case can be damaged. Drive vehicle only at a maximum speed of 30 mph (50 km/h). Do not drive vehicle in the upper load range or at full throttle. 1 Carry out the test procedure under the following conditions: • • • On a straight stretch from speeds less than 10 mph (20 km/h) accelerate the vehicle in the partial load range. During this test procedure, if: • • jerking can be felt, the test procedure under (below) must also be carried out in order to determine the exact cause. no jerking is felt, see the information below about normal vehicle behavior: 2017© Porsche Cars North America, Inc. AfterSales Sep 22, 2017 Page 3 of 8 3 Service 3995 ENU Technical Information 84/17 Information Generally, the vehicle can start jerking when driving in tight corners with a small radius and when Off-road mode is activated. This behavior is perfectly normal for all-wheel drive vehicles and is not a defect on the vehicle. 2 Conditions for the test procedure: • • • Activate Off-road mode in the vehicle and drive at low speed into a tight bend with a small radius (high steering angle). If jerking can be felt during this test procedure, work through the following steps, depending on which equipment is installed: • • with PTV PLUS (controlled rear-differential lock) – I-no. 1Y1 continue with 2.1 without front/rear differential lock – I-no. 1Y0 continue with Information Generally, the vehicle can start jerking when driving in tight corners with a small radius and when Off-road mode is activated. This behavior is perfectly normal for all-wheel drive vehicles and is not a defect on the vehicle. 2.1 Disconnect connector on the rear-differential lock control unit, see Workshop Manual '397519 Removing and installing control unit for rear-differential lock'. 2.2 Carry out the test procedure under the following conditions: Disconnecting the connector should prevent the vehicle from jerking due to a higher rear-differential lock locking value. 3 2.3 Re-connect connector on the rear-differential lock control unit, see Workshop Manual '397519 Removing and installing control unit for rear-differential lock'. 2.4 If jerking still occurs even with the connector disconnected, continue with step .
