Service
Misaligned parking aid sensors or various vehicle mountings can cause parking aid malfunctions. This TSB
provides tips for diagnosing parking aid systems.
1. Verify that the coding within the parking aid control module, J446 (address word 0076), is valid for the
equipment installed on the vehicle (i.e.: trailer hitch, tow bar, etc.).
2. Check the vehicle fault memory and proceed according to GFF.

publisher.
 If GFF identifies a problem with a specific sensor, proceed with the test plan.
 If GFF does not identify a specific sensor, check MVBs in the parking aid control module, J446 (address word
0076), starting with MVBs for oscillation.
MVBs for internal sensor oscillation (if applicable) (acceptable values = 0.8 to 1.5ms). If the oscillation is
not within specification, proceed to step 10.
MVBs for distance calculations (255 = no obstruction). If an obstruction is identified but none exists,
proceed to step 3.
Tip: Vehicles can be equipped with 4- or 8-channel parking aid systems. Refer to Elsa for vehicle-specific
information.
3. Check parking sensors (Figure 3) for obvious issues:
 Mechanical damage (stone chips, scratches).
 Dirt, ice, foreign bodies, foil adhered to sensor.
 Damage to the bumpers that may indicate an
accident (or paint indicating a previous incident).
Figure 3. Stone chips causing sensor failure.
Tip: Exterior damage to the vehicle, including stone chips and scratches, is not covered by Audi Warranty.
When painting sensors, the special painting instructions for parking sensors in the paint repair manual must be
observed.
4. Check for non-Audi Genuine Accessories which can interfere with parking aid operation, including:
 Aftermarket towing bar.
 Aftermarket lowering kit.
 Aftermarket spoiler or air deflector.
 Aftermarket bumper.
5. For 8-channel systems, check the installation of the front license plate holder for:
 Protrusion. The license plate and holder must fit on flat.

 Bent corners. Any bent-open corners may cause false readings.
 Correct fit. Oversized license plate holders or frames can obstruct parking aid sensors.
6. Pressure check for a tight fit and correct attachment of
the parking sensors (Figure 4). If the sensor is not
snug or feels loose, remove the bumper and reinstall
the sensor.

sensor.
7. Check that the decoupling ring is correctly seated
(Figure 5, Figure 6, and Figure 7). If the ring is folded
or bulging, remove the bumper and reinstall the
sensor.

8. Verify that the sensor is centered inside of the
mounting hole (Figure 8 and Figure 9). If the sensor is
mounted off-center, remove the bumper and reinstall
the sensor.

9. Ensure the sensor sits flush with the bumper (Figure
10 and Figure 11). If the sensor is recessed or bulging,
remove the bumper and reinstall the sensor.

10. Re-evaluate the concern:
 If an issue was identified and the concern was remedied, proceed to step 15.
 If no issues were identified and the concern cannot be duplicated, proceed to step 15.
 If the concern still persists, continue to step 11.
11. Remove the bumper and check the connectors on the sensors, the socket box of the bumper, on the control
unit for parking assistance and on the sound generator of the parking assistance for:
 Corrosion.
 Water ingress or water marks.
 Bent-open pins.
 Pushed-back pins.
 Correct fit of plug seal.
Tip: If a specific sensor is identified by the diagnostic tester, proceed forward for that specific sensor
only.
12. Check the cables in the bumper for damage and
sufficient length (Figure 12 and Figure 13). Cables that
are too short can cause damage to the harness.
 If the cable is damaged, repair the cable using VAS
Repair Kit 1978.
 If the cable is too tight, correct the routing by
moving the support clip so the cable is no longer
under tension.

length.

socket box for correct installation (Figure 14 and
Figure 15). If the connectors are not installed properly,
reinstall.

14. Re-evaluate the concern:
 If an issue was identified and the concern was remedied, proceed to step 15.
 If the concern still persists, swap affected parking aid sensors or control modules until issue is identified,
remedy the concern, then proceed to step 15.
15. Various environmental factors can cause incorrect warnings. Notify the customer that the following may
affect parking aid operation:
 High plants and curbs.
 Gravel paths, cobblestone paths, pot holes, grates, sharp bends in the road, slopes, driveways, or
ramps.
 Water on the parking sensors.
 Ice or snow on the parking sensor or the bumper.
