PDC not working and not sure where to look for the issue

tripberger · 01-09-2021, 08:34 PM

I have a 2016 F80 with rear PDC only (no front) and all of a sudden PDC stopped working and I get an error message on the screen. I have done all I can think to do to diagnose the issue. First I tried WD40 on each sensor. I didn't think this would work but I thought I would give it a try. Then I tried running the codes with Bimmerlink. I get the following 8032D0, 8032D8, 8032E0 and 8032E8. All 4 errors say "Ultrasonic sensor front outside right, center right, center left and outside left; Line-interruption". All 4 errors say front PDC which is odd as I do not have front PDC, only rear. I then checked all 4 fuses for the PDC. All look good. Then I figured it must be a connection issue as I just had the back bumper repaired. PDC was working for a week after I got the car back from the body shop. I removed the bumper and all connections look good. I'm not sure where to look next. Any ideas? Certainly all 4 sensors did not go out at once. I am out of warranty and don't want to go to the dealer unless I have no other option.

maybe disconnect the battery and let it sit for a few?

Thanks but I tried that when I was checking the fuses.

I would think the pdc control unit has failed, it's a codeable part so if it is that you would either need software or to get it coded.

The sensors make an audible high-pitch whine. Are any of them working, or are they all dead?

I had this happen to me on my previous car. Found the PDC wiring loom to the control module had decided to fail unexpectedly. Luckily the loom was only for the rear half of the car so didn't have to remove much and the loom wasn't a bank breaker either

Not Necessarily. Parking sensors can be completely silent depending on when they were made and by who.

So i had the same issue. Removed the bumper and checked the connection, it was corroded inside so im going to have to cut that one off, and replace the connector. Moisture must've gotten in.
