Got a golf III with msa12 here, just fitted a new map sensor (o51c), n75 and 2056v. I´m trying to get an msa15 (16bit) ecu to work, but cant match the unit with vagcom because its not even recognizing it. My question is, what needs to be done, do i need to kill immo? Cheers

Problem solved, tried with another msa15 and it starts, problem must be with soldering job.
