Hi there, I had the same problem and had to take the rear bumper off. Just remove some of the plastic trim in the boot and then 6 nuts hold the bumper on. To test the connection plug use a multi meter on the continuity setting. One of wires turned out to damaged near the plug end. Soldered in a new section of wire . Hope this helps
Posting this for anyone else trawling for solutions as I know it’s an old video. There is an issue in that the two outer ones MUST be genuine but the inner two can be aftermarket. Note you can use Landrover (Valeo) parts as Valeo were the OEM manufacturer apparently and much cheaper than BMW dealers - this is the best article I found: forums.m3cutters.co.uk/threads/cheap-pdc-sensors-no-good.106767/
I have similar problem with my car. When put in reverse (auto gear box) long beep sound about 3s occurred. Two of four sensors weren't clicking. I saw that the connectors were not plugged in good. I clean the connectors and plugged in and have clicking sounds of every 4 sensors. Than start the procedure and car works perfectly but only 5min .After that i lose every sound in cabin.Now wouldn't beep when i put in reverse or when parking nothing.The sensors are clicking but i lose the sound.
I have the same issue on my M3. Just saw another video from DiagnosticWorld. Looks like if sensors fail, it should trigger a code - it actually tells you which sensor is malfunctioning... Which also has to be cleared once sensor was replaced.
xiaorpowr it's not the sensor's it's the control unit in the glove box where the fuses are, £19 for a 2nd hand uniylt on eBay swapped them over and now works perfectly.
Andrei Alin . No sorry nothing I've tried has worked, checked all fuses I even changed the sensors themselves and gave the rear bumper a good clean but still no luck. they do work now and again very frustrating but when I do get them to work I will upload a video asap.
Hi mate you don’t need to remove the bumper.. the black plastic trim across the whole bumper which the sensors sit in removes separately prise of from the edge and pall. I did it myself very easy fix.. I’ve replace all my sensors and I’m just waiting for the fault reader to clear the error code
Caius Dehelean sorry still not working, I've changed all 4 sensors and checked fuses still got the problem. Think It could be a wording issue? sorry can't be more helpful.
Lee Murphy you must replace the white plastic box, where PDC is standing on. It‘s right in the package room under one of this carpet covers. There ar normally two plugs with about 10 cables. One is white and one is i think blue at the E46 and violet at the E39.
The 2 outside sensors need to be oem ones. Centres can be eBay ones. Hope this helps anyone
Hi Emzo. Same problem here... when/if I´m able to solve it ill post the solution here!! chears

Emzo Daniels brilliant thanks, this is very helpful
Emzo Daniels hello i have E46 320d 2002 can you post me link on that pdc control unit from ebay .. My email Fkovac@centrum.sk thank you so much
@@emzodaniels5011 where exactly is the control unit pls? I have taken down the whole compartment and I cant figure it out just yet.
wow didn't realise how loud it was until it was uploaded on TH-cam. but as you can see all sensors are working/ ticking so don't now what's wrong.
Emzo Daniels you solved the problem? I got the same problem

Did you find the problem? i have got the same problem
I now have the same problem, have you solved it?
got a similar issue one of the sensors stops working sometimes but it works out of the blue othertimes am so confused
I changed 2 sensor what has been shown fault on a diagnostic machine and its still not works.😤
Hi! Have the same problem. You resolve the problem in the end?
Caius Dehelean sorry still not working, I've changed all 4 sensors and checked fuses still got the problem. Think It could be a wording issue? sorry can't be more helpful.
Did you get it fixed mine is doin that too

@@andrekrenn2198 where can i find this white box in detail? Im from the netherlands
same problem here but can be from pdc speaker
what about when my sensors dont work but they dont make any noise? The fuse isnt burnt either
have you checked the front sensors are working? If one doesn't work the system won't work
steven kennedy hey Steve no sorry No front sensors just the 4 rear. I've decided to change all 4 rear sensors now see if that works.
Mine is a continuous beep in every gear even neutral as soon as the engine turns on it’s a constant beep
There is a module in the boot. Could be that...
Andrew Bond thanks I never knew that will take a look straight away.
hi there where abouts in the boot is it please ive got 325 compact and mine doing the same
A thought module was behind glove box?
