WiNgNuTz Posted February 15, 2017 Report Share Posted February 15, 2017 Having seen a thread on here, I checked my parking sensors when the vehicle was in reverse, I can hear the clicking noise from each of the 4 sensors (which leads me to believe the sensors are all working as they should be), but I get no audible warning in the cabin. I'm pretty new to BMW's in general, only had my 320d Touring for 3 weeks so far, so could anyone suggest where I should check next? I'm guessing there may be an issue with the sound side of it, as the user manual states "System malfunctions will be indicated by a continuous high-pitched tone when the system is activated the first time", and I have no feedback whatsoever to inform me whether the system is working or not.

Megadodo Posted February 16, 2017 Report Share Posted February 16, 2017 Its is possible that the speaker for the system is faulty or disconnected. It can be found under the dash on the R/H side. Unless you have access to a proper OBD code reader then your only option is part swapping for a diagnosis. WiNgNuTz 1 Quote Link to comment Share on other sites More sharing options...
WiNgNuTz Posted February 16, 2017 Author Report Share Posted February 16, 2017 Awesome, thanks for that, I shall have a gander and see if I can find it to start with, if it's disconnected then ace, if not, I may know a man with a spare I could try.

WiNgNuTz Posted March 2, 2017 Author Report Share Posted March 2, 2017 So I swapped out the speaker unit (or "gong" as it was advertised), to no avail. Anyone got any other suggestions before I go searching for any dodgy wiring? Are any of the bits in the near side cubby hole in the boot related to the PDC?

AndyC_67 Posted March 3, 2017 Report Share Posted March 3, 2017 Hi there, I have a similar problem ....although when I put it in reverse I get a couple of beeps then a solid beep. I have disconnected the speaker until I get round to sorting it out (better weather!). The clicking is no real indication that the sensors are OK. I plugged the car into INPA and you can see all sensors individually working then one goes full on....so I know which one is faulty. Quote Link to comment Share on other sites More sharing options...
WiNgNuTz Posted March 5, 2017 Author Report Share Posted March 5, 2017 I don't even have a beep when I select reverse though, absolutely nothing. It's not bothering me too much, as I just make use of my mirrors instead of relying on the sensors, but it'd be nice to have it working.

Trevor Posted March 5, 2017 Report Share Posted March 5, 2017 Sensors clicking doesn't mean working. But not clicking however does mean not working. INPA will do a live test and this showed one of mine to be faulty although it still clicked. Changed out the bad one and all was good. momo 1 Quote Link to comment Share on other sites More sharing options...
