PDC Problem

[marcop123]

Hi
I have recently purchased a BMW Z4 coupe E86, prior to owning it has had a bumper smash and the rear bumper replaced but no PDC, a mechanic ran diagnostic and showed PDC installed but faulty and he said it looked like the sensors still in car somewhere but since then for audio upgrade the interior was just stripped and no PDC modules were found. When I go into reverse it gives the 1 long beep which signifies PDC error

I’m not sure by the diagnostic is any chance when bumper replaced they left the PDC modules inside it but didn’t drill the holes although this strange but what sort of what diagnostic showed or likely diagnostic shows PDC module installed or connected but simply faulty but mechanic was convinced the 4 modules still attached in car somewhere.

What all do I need to get the PDC working ? Is it the case I just need 4x of the after market modules and that all I need ? My car booked in a week to finish up the audio upgrade of Jehnert audio system and just struck me if easy enough job get him to do it also but rather just order all I need and turn up with it next week

Any advice what I need would be appreciated

Cheers

Are you sure? I have enabled initial tone on selection of reverse, which is a codable option, lasts about a second.

Can you check your z4 build included PDC?
The module in my roadster is in the boot on the right hand side just in front of the light cluster behind the carpet. You could check to see if there is anything there.
As scooba_steve has said, it might be a coding option.

Yeah it definitely has the PDC module , im figuring I just need to buy the harness and the 4x PDC units I haven’t been able to find original oem used on eBay so seems if installing 4 aftermarket the seem it should be ok from what I gather

My previous Z4 had been retro-fitted with PDC and was coded for that beep every time I selected reverse gear and it did my head in.

Thankfully someone with Carly was able to stop it!

Good luck getting yours working.

Yeah originally just thought part and part but after some days was doing my head in then more so when discovered it was actually a fault and now want fixed but since the 2/3 months getting my coupe it’s been project project project but as my car was totally stripped which was actually good to see apart and back together all interior apart and after 8hrs solid from audio installer he had to call it a day and due back in this Friday but all hard work done just need to fit new door membrane as was leak, fit new crossovers in door and wire all 14 speakers haha 14 is far what I started out as but hoping all going to come together and sound amazing !
But yeah if can get PDC done at same time as boot carpets etc no back on yet , sound dampened whole car again wasn’t plan but had extra dampening due to front already been done.
