So I'm kinda stuck now with my park assist retrofit and have exhausted all ideas I have shy of purchasing a new PMA module. Steps so far.

Created a loom for the retrofit. Twisted pair for the Flexray and also the LIN bus etc for the sensors (all following the Rheingold instructions/wiring diagrams) 
Ran wires at the same time as running the side view cables for my bumper cams. 
Installed PMA in boot and wired to fusebox (I even ordered an uncoded fuse holder to ensure it was wired to F134 as per Rheingold instructions.) 
Checked 14v supply to plug to PMA, ran ground wire to ground connector in boot.
Ran Flexray pair from PMA to ZGW (I have the 8SK High) pins 1&2 as per Rheingold.
Using tool32 opened port 0x07 and checked it was open.
Flashed up esys.....no PMA visible.
Checked continuity of Flexray pair, all good. Checked supply to PMA, all good. Moved the pins from 1&2 to 11&12 and opened port 0x03, checked with esys, again no PMA! Decided to open all ports with tool32, still the same, no PMA! I then double checked my loom and PMA connector. All is good. Power, ground, Flexray pair and flexray termination all present and correct. It leaves me with 2 thoughts. 1 I've got the flexray termination wrong. I have a pink wire going from pin 15 into 17 and a green wire going from pin 16 into 18. 2. The PMA module is defective.

Can anyone shed any light or offer some advice? Have I missed a step? I know a few people have completed this retrofit as I've been taking advice from their posts. I'm pretty lost at the moment as nothing I try or do seems to work.

Thanks
