Audi a5 3.0 tdi parking sensor/module issue.

[Siray11]

Hi everyone.

got a really annoying problem with my parking sensors.

system has stopped working, light flashing by gear stick and one long constant beep.

plugged the car in and the fault code pointed me to the front nearside sensor.

ordered a new sensor from audi and fitted it, problem solved.

24 hours later, problem returns, fault code is the same sensor.

stripped it apart and the sensor was wet as was the plug connector, took it back back to audi and they changed it for a new sensor.

Dried the plug out, fitted new sensor, no joy cant get the system
to work at all now, tried the new sensor in other positions so the sensor is ok.

tested the cabling from the plug position back to the multi plug on top of the rad and this is ok.

very frustrated now and stuck for ideas.

the next point is the parking ecu, which is an easy fix. However do these units go wrong, is there anyway of testing it before i commit to buying a new one and if its not this then im really stuck for ideas!!

Please help, getting really p$€^ed off now, normally i love my car, hating her at the min.

thanks in advance.

Do you have the exact fault code and vcds log extract for module #10?

Hi chris

No i havnt got this info i maybe to get it on monday.


The garage have told me that it keeps flagging up that the front nearside sensor is faulty however we have determined that the front sensor is ok and the wiring from above the rad down to the sensor is also ok.??

Thanks
