markfireblade Posted May 28, 2016 Report Share Posted May 28, 2016 Car is a 2003 325i. Been getting the long beep with no PDC function for some time. Finally got INPA and a suitable cable, plugged in the laptop, INPA says left centre sensor is faulty. Replaced it with a spare used one and that one now works, but none of the others do. The really weird bit: INPA says no faults and there is no long warning beep. If I move the good sensor to any other position it works but none of the others do. Still no faults shown on INPA. Any clues anyone? Cheers Mark Quote Link to comment Share on other sites More sharing options...
momo Posted May 29, 2016 Report Share Posted May 29, 2016 Had similar on my brothers old 320d.. Ended up replacing all 4. That sorted it! Quote Link to comment Share on other sites More sharing options...
markfireblade Posted May 29, 2016 Author Report Share Posted May 29, 2016 Ah OK. Odd that INPA doesn't pick up any fault codes. Quote Link to comment Share on other sites More sharing options...
momo Posted May 29, 2016 Report Share Posted May 29, 2016 I never relied in INPA for these tbh.. You should be able to hear a good, strong click from each sensor. You'll find the one you replaced is probably clicking much stronger than the others. Quote Link to comment Share on other sites More sharing options...

chocka Posted May 31, 2016 Report Share Posted May 31, 2016 i have an intermittent fault, works properly 80% of the time but keeps failing every so often, can work, fail and work again in same day. Quote Link to comment Share on other sites More sharing options...

markfireblade Posted June 5, 2016 Author Report Share Posted June 5, 2016 I've replaced one more sensor (to see what would happen) and that's now working too. Looks like they all needed chucking... Quote Link to comment Share on other sites More sharing options...

I have a similar problem. It doesnt pick up items until its quite close to them so I have to be really slow. It picks up solid items (walls, other cars, etc) but thin items (parking poles, lamp post, etc) it will continue beeping like its close but before the beeping turns to a solid sound it'll be bumping off items. Very frustrating! Quote Link to comment Share on other sites More sharing options...
