Production Solution
Not applicable.
Service
Please note that before performing this repair for the first time, it is mandatory that the technician complete Audi
Academy Course #940134 and assessment #940134B. Otherwise, the warranty claim will be denied. The
course and assessment can be found on the Audi Academy CRC site. Specific video sections are referenced in
the instructions below.
Perform ODIS Testing – For all but A6 (C6) 3.2FSI and Q7 3.0T:
1. Delete all DTCs. Bring the engine to operating temperature.
2. Go to Control Modules >> 01 Engine Control Module >> Control module OBD>> Basic Settings >> Checking
Secondary Air System.
3. Select MVB: MASS_SA_REL[0] and MASS_SA_REL[1].
4. Perform test (Press brake and gas pedal at the same time, start test on ODIS tester).
5. While Basic Setting test is running, check if the secondary air pump runs normally (no unusual noises). In
addition, check for a leak in the secondary air hose routing between the pump and combi valves.
6. Immediately after the test is complete, read MASS_SA_REL[0] and MASS_SA_REL[1]. Depending on the
software level and engine code, the air mass flow will be displayed in one of two ways:
 For old software version:
If the value is between 0.1 and 0.7, and there were no issues with the pump and hoses, the system needs
to be cleaned. Follow the instructions below.
 For new software version:
If the value is between 13 and 16, and there were no issues with the pump and hoses, the system needs
to be cleaned. Follow the instructions below.
Perform ODIS Testing – For A6 (C6) 3.2FSI and Q7 3.0T only:
1. Go to Control Modules >> 01 Engine Control Module >> Control module OBD>> Basic Settings >> test 77.
2. While performing test 77, check if the secondary air pump is running and make sure it does not make any
abnormal or unusual noise:

 If test 77 fails but the pump is running and does not make any abnormal/unusual noise, perform the
cleaning process below.
 If the pump is not running or if it makes abnormal/unusual noise, this TSB does not apply.
Tip: Always use the latest version of this TSB.
Prepare for Power Washing:
1. Move the exhaust sliding bushings
(that connect the catalytic converter
and muffler) back, then lower the
catalytic converter pipes (Figure 7).
For Q7, unbolt muffler from catalytic
converter. Cover mufflers with plastic
bag to prevent water from entering.
Cleaning water will drain out of the
catalytic converter pipes during the
cleaning process.
Figure 7. Lowered catalytic converter pipes.
2. Remove all spark plugs and cover the engine harness plugs for the coils (for water protection).
3. Drain the coolant so that it can be reused.
4. Bring front end of the car into service position (for Q5, A6, S4, and S5 Cabriolet) to make room in the front of
the engine. The Q7 has enough room for access to the front of the cylinder heads.

 Coolant flange (Figure 9, image
2).
 Pulley and if needed bracket, of
power steering pump (Figure 9,
image 3).
 Pulley of water pump (Figure 9,
image 4).
 Coolant tube (Figure 9, image 5).
 Dipstick tube (Figure 9, image 6).

Note:
To loosen the coolant tube, remove 2 bolts (Figure 10, image A and C), open
clip (Figure 10, image B), and pry bushing apart as shown in training video
(Figure 10, image D). There is no need to loosen the AC compressor.
Cover opening of right coolant pipe to prevent coolant circuit contamination.

coolant tube.
7. Remove main port freeze plug by
hitting the marked area with a small
punch until it turns (Figure 11).
Remove with pliers.
Figure 11. Marked area on main port of freeze plug.
Prepare to Power Wash:
Warning:
 Read pressure washer user manual and follow these safety instructions.
 Always insert special cleaning hose into adaptor and engine before turning pressure washer on.
 If switching special cleaning to a different port, turn pressure washer off and release residual pressure by
pulling the trigger before removing the special cleaning hose from the engine.
 Wear safety glasses and gloves.
1. Become familiar with the special tool set VAS6825 (Figure 12):

4. To ensure proper pressure washer function, use a ¾-inch water supply hose (no longer than 60 feet) to
supply pressure washer.
The Audi-supplied pressure washer comes with a 22mm male-to-male adapter (to connect special tool to
trigger gun), a pressure gauge (to connect between pressure washer and high pressure hose), and a 220V
power adapter.
Make sure that pressure is at least 1800 psi when using the special single port cleaning hose (the hose with
the scale). Use the table below to compensate for low water pressure:

Power Wash the Ports
Cleaning Main Secondary Port:
1. Insert special main port cleaning hose (the hose without the scale) two inches into the engine adaptor.
2. Turn the pressure washer on.
3. Holding the cleaning hose tightly, pull the pressure washer trigger.
4. Gradually move the cleaning hose into the port, going back and forth until the combi valve is reached. All
water comes out at the adaptor #4.
5. Continue going back and forth through the whole port until only clean water drains out of the cylinder head.
6. Do the same with the other cylinder head.
Cleaning Single Ports:
1. Because every port has a different distance to the cylinder head, use the table below to position the hose
adaptor for the special single port cleaning hose (the hose with the scale) correctly into the hose. The back
side of the hose adaptor must align with the number on the scale of the cylinder to be cleaned (Figure 15).
The longitudinal slot on the hose adaptor must align with the black line on the scale for correct rotational
positioning (Figure 15).

the hose adaptor within the longitudinal and transvers slots (Figure 16).

Tip: After ten seconds of cleaning, all of the water should be draining out of the exhaust. If water is draining
out of the engine adaptor, check the position of the hose adaptor on the hose.
5.
Do the same for all remaining cylinders.
6.
It is recommended that after cleaning, all single ports
are checked with snap-on boroscope BK6000 (or
similar, with 90-degree lens), to make sure all ports
are clean (Figure 17).
Figure 17. Clean single port.
7.
When all carbon is removed, install a new main port plug using an 8mm socket with a short extension,
paying special attention to install it squarely. The outer edge of the plug should be recessed ~0.5mm – 1mm
behind the outer cylinder head edge.
8.
Reinstall all components (except spark plugs) and fill system with coolant according to ELSA.
9.
Using a vacuum extractor, remove all water from all combustion chambers.
10. Make sure all water is removed from the combustion chambers by using the self-start function twice
while the spark plugs are still removed (cover spark plug openings with a towel). Install spark plugs and
coils.
Make sure water is completely drained out of exhaust (make sure the exhaust is lowered enough).
Tip: There is no need to replace the engine oil; almost no water drains into the oil pan.
11. Allow the car to run at idle for 15 minutes to ensure that any remaining in the exhaust system evaporates.
After Power Washing:
1.
Delete all DTCs. Bring engine to operating temperature.
2.
Go to Control Modules >> 01 Engine Control Module >> Control module OBD >> Basic Settings >>
Checking Secondary Air System.
3.
Select MVB: MASS_SA_REL[0] and MASS_SA_REL[1].
