After discovering the wiring present, I obtained and fitted a set of electric memory seats. (into a mk2 ZT diesel auto). I have an aftermarket stereo initially Kenwood, and latterly Alpine, with a single 4 channel amp. The seats were fitted after the amp and Kenwood stereo. They were plug and play. Memory, heat and electric operation were all fully operational. They still operated after the Alpine was installed, and power cable for the amp re routed.

I assume them to have remained operational until I had the crank pulley and injectors replaced. I know it was put onto a T4 at the time, as the map was adjusted. It was about a fortnight after I discovered the memory was not operational. I didnt contact the guy that did the work (he is a very trustworthy and capable specialist) as since it didnt bother me, I didnt want to disturb him lol, and besides I can assume it just as possible to be a coincidence.

I have read up, and it seems the memory ECU can be a possible issue - non memory apparently do not have the ECU (?). A couple of weeks ago, I serviced it, and resetting the oil service indicator with Phil's IPK tool, I started up TOAF to have a look at it. All seat functions were accessible on TOAF. The seat ECU showed the VIN from the car they came from, and I did not know if or how I could change it (but it shouldnt matter since it worked previously, unless the T4 has seen an issue with the mismatch and disabled it?)

So is it possible that T4 has disabled it due to the mismatched vin? or could it be a seat ECU issue on RSNAIL's car, with the kbus being a coincidental and additional issue?

I don't think the vin so much as the ZCS coding
