PDC Malfunction

Does anyone have any experience with the PDC malfunction error? Last week I started getting the error message. I used DIS and it told me that the center left sensor had an open short to ground. I searched the internet, but did not find any good answers. I removed the front bumper cover, & checked all of the wiring. I even swapped sensors to see if that would make a difference. After checking for any broken wires on the front harness, I could not find a broken wire. I then checked for a broken wire to the PDC control module. All wires seem to be good. I used contact cleaner on all connector's.

Is it possible that I could have a bad module causing this error? DIS gives a test sequence for the wires, sensors, & control module. All test say short to ground. Does anyone have any experience with this type of problem? I even tried to swap the wiring from front to rear at the module, but they are made different. Each sensor had 1 wire showing 12.66v, so I know that they have power going to each sensor. All grounds are going back to ground.mI thought about swapping the module off of my 750, but I do not want to damage it.

Thanks

Anyone?

HerbP my tech guy swapped my old one with a used one and it worked!!! He said the same thing "water" I guess BMW can't put a bead of silicone on there module. $295 was the price I payed for the module.

I recomend you buy it use i pay ..$100 for mines already programmed.

What symptoms & warning were you getting? Did you get any codes? It is hard to see how water could get to this module based on its location.


Thanks

I like your parts brake down view. This is probably the best I have seen! I have you bookmarked!

First off the pds light would flash whenever i presses it. When i reversed the car the graphic display would show but no sound or color shadding would occur. Absolutly no sign of water damage, I dont beleive water got into it but its possible because of its location. If you have any friends with bmws of that year ask them if you can swap modules just to see if thats theproblem or else yoir stuck bringging into the shop. Hope that helped.

I finally got around to repairing my PDC problem today. As Mulchman said, it was a bad front wiring harness problem. I am glad to get it working again ! A 64.00 repair!

Thanks Mulchman!
