Various environmental conditions can cause false activations to be seen by the customer. In cases
where the customer is reporting several false activations (parking aid warning is displayed however
nothing is around) the below environmental and vehicle contributors should be checked.
Environmental Conditions
1.
Plants growing to certain heights, and curbs can lead to incorrect warnings being issued in the
vicinity of the vehicle.

Technical Service Bulletin
2.
Gravel Tracks, cobblestones, potholes, cattle grids, sharp bends in the road, and slopes can lead to
incorrect warnings being issued.
3.
Various types of weather/ambient conditions can lead to functional issues:
• Water on the parking aid senders (widening of the radiation pattern).
• Ice/snow on the parking aid senders or in transition to the bumper.
• Vehicle exhaust gases and water vapor (bursts of heat caused by revving the engine) alter the
physical property of the air needed to transport the ultrasound of the parking aid system.
• Noise disturbance (pneumatic brakes of heavy goods vehicles, anti-rodent devices, or other
active ultrasound sources in the vicinity, such as parking aid systems in other vehicles).
4.
Immediate surroundings
• Fluorescent tubes.
• Induction loops at traffic lights and car park barriers.
• Ramps/Driveways.
Vehicle
1.
Check installation of the license plate and carrier with regard to the following points:
• If possible, do not use any advertising carriers.
• The size of the license plate must be identical to that of the base carrier.
• Ensure that the number plate and carrier are secured correctly at the side edges (edges bent
upwards)
2.
Add-on parts/modifications/retrofits which are not Audi Genuine Accessories could lead to an
erroneous warning being issued.
• Trailer hitch.
• Lowered ride height.
• Spoilers.
• Bumpers.
• Sound generators.
• Anti-rodent devices.
3.
Previous damage where a new coat of paint has been applied (refer to repair history).
Checks without disassembly
Misaligned parking aid sensors or various vehicle mountings can cause parking aid malfunctions. This
TSB provides tips for diagnosing the parking aid systems.

Technical Service Bulletin
1.
Confirm that there is no obvious obstruction due to aftermarket components, physical vehicle
damage, excessive dirt/snow, or stickers.
2.
Check the vehicle fault memory and proceed according to GFF.
• 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 master module for the parking aid
sensors. Based on the vehicle, these can be found in the guided functions or OBD of modules
09, 76, or A5.
Below is an example of module 76 MVB. When diagnosing the system you can check the
response values for the sensors. Compare the sensor values to one another while moving a test
object closer/further away, they should all respond similarly.
MVBs for distance calculations (255 = no obstruction). If an obstruction is identified but none exists,
proceed to step 3.
Vehicles can be equipped with 4, 8, or 12 channel parking aid systems. Refer to Elsa for vehiclespecific information.
3. Check parking sensors (Figure 3) for
obvious issues:
• Mechanical damage (stone chips,
scratches).
• Dirt, ice, foreign bodies, and/or foil
adhered to the sensor.
• Damage to the bumpers that may
indicate an accident (or paint indicating a
previous incident).

Technical Service Bulletin
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. 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.
Figure 4. A pressure check on a parking aid sensor.
5. Check that the decoupling ring is correctly
seated (Figures 5 - 7). If the ring is folded or
bulging, remove the bumper and reinstall
the sensor.

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

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

8.
Remove the bumper and check the connectors on the sensors, the socket box of the bumper, on the
control module for parking assistance, and on the parking assistance sound generator for:
• Corrosion.
• Water ingress or water marks.
• Bent open pins.
• Pushed back pins.
• The correct fit of plug seal.
If a specific sensor is identified by the diagnostic tester, diagnose that specific sensor only.
9.
Check the cables in the bumper for damage
and sufficient length (Figures 12 - 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.

installation (Figures 14 - 15). If the
connectors are not installed properly,
reinstall.
