Pdc ground to earth fault

[Kevo]

Hi, 

Has anyone had a fault with the pdc, where if you unplug the front loom from the module, you can here the rear sensors clicking, but when you plug the fronts back in, none of it works.

is it a simple earthing fault, or failed module, or one of the sensors has failed?

Thanks.

Hi Kevin Welcome to the Forum

If 1 sensor has failed it throws the lot out, so from your symptoms one of the front sensors has died. The sensors tend to be flaky at best my rear sensors show a fault when I scan the system when it's cold out (5 or 6 deg) when its warm like now they work fine they also hate the jet wash?? Cleaning the contacts and plugs cant hurt and is free from memory all 4 sensors on the front of your car are same but check www.realoem.com to be sure if you put the last 7 digits of your Vin number in the search box it will bring up your car. Have a look at www.newtis.info as well that is a BMW technical information site same information as Dealers use for how too's

Good luck

Dave
