Initial publication
• During reset of the service reminder, the following message appears on the ODIS tester: “AIR system action required - observe test plan” (Figure 1).
Figure 1. Message on ODIS tester.
• MIL is not illuminated.
Technical Background
Under certain driving conditions, the secondary air ports in the cylinder head can accumulate carbon over time,
causing a restriction. The ODIS tester can identify the state of the restriction, and will request that the system is
cleaned in order to prevent the MIL from illuminating.

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 reference in the
instructions below.
Select the test plan in ODIS
1. In the ODIS tester click on the “AIR system - action required - observe test plan” message to follow the test
plan (Figure 2).
Figure 2. Message on ODIS tester.
2. Select -2- for Cleaning. Follow the test plan, which is also outlined below.
3. Check the hosing between the secondary air pump and combi valves as instructed in the test plan.
4. Based on instruction from the tester (“clean immediately” or “clean within next 1000 miles” -- based on level of
restriction), clean the secondary air ports according to the instructions that follow in this bulletin.
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 4).
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 4. Lowered catalytic converter pipes
2. Remove all spark plugs and cover the engine harness plugs for the coils (for water protection).

engine. The Q7 has enough room for access to the front of the cylinder heads.
5. For 3.0T only: remove the coolant supply lines
(intercooler of supercharger) in the front of the engine
(Figure 5).

Note:
To loosen the coolant tube, remove 2 bolts
(Figure 7, A and C), open clip (Figure 7, B), and
pry bushing apart as shown in training video
(Figure 7, D). There is no need to loosen the AC
compressor.
Cover opening of right coolant pipe to prevent
coolant circuit contamination.

7. Remove main port freeze plug by hitting the
marked area with a small punch until it turns
(Figure 8). Remove with pliers.

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 6):
• Special hose with scale for cleaning single
ports (Figure 9,1)
• Special hose for cleaning the main ports
(Figure 9,2)
• Hose adaptor for the special hose with
scale (Figure 9,3)
6 • Engine adaptor for bank one (Figure 9, 4a)
• Engine adaptor for bank two (Figure 9, 4b)
Figure 9. Special tool set VAS6825
2. To catch water, put a pan under the front of the engine and under the disconnected catalytic converter pipes.
3. Install engine adaptors on the appropriate banks (Figure 10, Figure
11).

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 12). The
longitudinal slot on the hose adaptor must align with the black line on the scale for correct rotational
positioning (Figure 12).

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 14).
Figure 14. 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]

4. Perform test (Press brake and gas pedal at the same time, start test on ODIS tester).
5. Immediately after the test is complete, read MASS_SA_REL[0] and MASS_SA_REL[1]. If the value is above
0.7, the cleaning was successful.
