Intermittent PDC failure
Does anyone know how to track down which PDC sensor is faulty, it's hard to bloody park these things when you have no sensors or they just switch off half way during parking. I would take it back to the BMW but I don't have the time to sit around for 1 whole day only to be told they have to order the sensor. Just need a quick fix until January when the car is due its MOT then I can get it sorted properly then.

The sensors make a clicking noise when they are working. Put your ear up to the bumper and if one doesn't make the noise it is bad or the connection is loose.

Are the sensors wired in series? Can I miss out that sensor?

each unit its wired to the unit in the trunk of the car... i dont think you can bypass one.

I ordered newones o e-bay and painted them myself.. much cheaper.. but i guess parts are vheaper in US than Norway anyway...

I ordered PDC sensors from some guys in latvia on ebay.. 100% new and working for about 1/3 of the price the dealer in Norway gave me... and som spraypaint....

Just turn on your system and use your ear to find the broken one.. or connect a computer and it will tell you what sensor is bad.

The only problem is when I put the car in reverse and then get out to listen the car automatically puts itself back into park :( I will have to get someone to sit in my drivers sit whilst I listen tomorrow.

Just another quick question. Even if the PDC failure comes up will I still hear the sensors clicking.

The full story is it only started happening one day when it was raining really heaving, I noticed one of my front sensors kept on bleeping even though nothing was in front of the car and then the PDC failure came on. But if I've been running the car for long the fault will clear and it will start working again until I switch the car off and then on again. It's clearly annoying me because the car is difficult to park (I think) without these sensors when you're so use to them.

Would I have to drop my bumper to fit these sensors (I'm soooo not a mechanic)

Thanks to all which has replied
