You haven't told us the part number of the unit nor what vehicle it's for..?? Mk6 or Mk7..?? Year model..?? Euro-3, 4 or 5..?? FWD or RWD..?? Custom or normal van..?? Camper, Luton, recovery or tipper..?? What accessories are fitted..?? 5 or 6 speed..?? 2.0L, 2.2L 2.3L, 2.4L or 3.2L..??

There's too many variables and each PCM will differ from the next depending on what you have.

Normally a change in the part number suffix will possibly be a minor PCM design change or even a firmware update, but unfortunately we won't know what that change would be or what it does.

Just tested that ecu, and it works fine, no fault codes etc.

But i still got little priblem, i cant get on to pcm, it just get "Service procedure has been interrupted"
Text on forscan, i have right cable and i bought extented licence, but still no
Connection.

Car runs fine
Fuses are good
Relays are good and new.
Power comes alla right sockets
Measured obd Port, all good

Losing my mind.....
