Hi guys got a problem with PDC the light flashes and shows on the screen but no sensors are working
I listened to all the sensors and found one that had a very faint ticking noise so I replaced it and all seem to be
ticking ok but still getting the error I checked all the connections and made sure there was noting blocking any of the sensors ,
I also tried another PDC module just to be safe and that's not the problem either
anything else worth checking before taking it to my local bmw garage and spending a lot of money ?

edit: they started to work a couple of times tonight but then threw up the PDC error and stopped working again

 

bump

 

I'm having the same issue...PDC works fine for one day and goes haywire the next. It seems that if one sensor fails, the whole system crashes. Everytime i check them they seem to be working okay, so I don't know what to do. Giving you a bump for anyone else to chime in...
