Need to inspect connectors on each pdc sensor. Also look at both front and rear bumper harnesses. They is where I have found most problems. If you can pull codes it will point you to what sensor is the problem.

Hi sfbimmerman - yes, I have the same (PDC Failure when car is started). You can tell which sensor is faulty by the following:

- get someone to sit in the car, engine on, put in Reverse (keep in park and Parking brake on)
- then go to the rear of the car, and put your ear against the first sensor - you should hear a 'clicking' sound - if you do, then go to the next sensor and so on....
- I would also do the same for the front sensors, putting car in Drive etc.

then, when you have identified the culprit you can remove it, replace it and all should be fine.

Hope this helps

Neil

Hi all,

on the same topic, so hopefully not seen as hi-jacking the threads :-)

I did the 'ear-test' as I previously described and found one sensor out.

However, yesterday I had the opportunity to run diagnostics on my 7, and the following showed up:

PDC - 9E2D -Transducer, rear centre left
PDC - 9E2E -Transducer, rear centre right
PDC - 9E36 -Transducer lines, rear centre right

Interestingly, only the 'rear center right' failed the 'ear test'.

BUT, my question is what does PDC - 9E36 -Transducer lines, rear centre right mean?

Anyone had this error and if so how did you fix it?

thanks
Neil

Transducer lines- pdc harness. Think about it: how computer knows if it's either harness or sensor, since harness is okay and not damaged it's your sensor, but inpa will throw 2 codes just in case which is smart I think.
Once again:
Ear test worked great lots of times better than inpa. Simply replace those ones which don't tick, and then if it didn't fix pdc- reset errors and run it again.
