Do any of you fine folk know what the difference is in the Parking Aid Modules? Or have you fitted one with a slightly different part number?

Mine has the forbidden coffee in it! It's like it's. not even trying any longer which is disappointing as most of the parts are still there :rolleyes:

There are a lot of these used on eBay which all have the 15K866 part number but the ones that start AH42 are really expensive and I can't see that there can be much to choose between them so I'm just wondering if anyone knows what the difference is (guessing it's a HW revision).

Also, can anyone point me at a good thread covering water ingress as I fear the signs are there for me and that needs resolving ASAP.

Cheers

The 15K866 is the standard designation for a PDC module in Ford-speak, the prefix is for the specific MY & model or system architecture, the suffix is (usually) for the software or hardware revision level.
The same part for a Ford focus or Kuga 09-14 has a DV4T prefix and may or may not work - and will almost certainly be a rear PDC only module. A prefix of BJ32 will work in an L538 but will not communicate in an L322, neither will an AH42 (Discovery 4)

So yes, short answer, you need the same prefix!
 
Thanks, that's some interesting insight. I realised that I have a whole spare car currently as I haven't sold it and decided to try the unit from that in mine. I thought it would also tell me if I could use a different prefix. I swapped it into my current car and hey presto, everything works. That unit was also and AH42 so that is clearly the one I need. I'll order one today and that will be another thing fixed.
