PDC not working

[Subwoofer]

Hello all, so my PDC (front and rear) has been messing up. It was working originally. Then the PDC button flashes green... now it’s not flashing.

I have plugged into INPA and ISTA.

The car recognises the gear going into reverse, and clicking the button. There are no PDC codes.

does anyone have any idea what I can do ?
Many thanks,

Start with taking your trunk/boot apart and look for water leak.

Thanks, I’ll plan to do that today, as long as it’s not raining. If on the odds there isn’t a water leak then what ?

CONTROL UNIT ?

Yep. Control unit likely. Possibly from water damage.

Annoying... you wouldn’t happen to have a part number for the one I need ? It’s a 2007 E93 N54 automatic, if that helps ?

I may as well buy one; as I’m taking everything off

Hello, I’m a bit vacant when it comes to part numbers...

Here’s a pic of my unit, I’m hoping you can help me in the right direction...

6982396 is the nbr you are looking for.
