I have a laptop setup for coding and have successfully coded a lot of different things on it using NCSExpert so I know the setup works but I just recently installed the OEM trailer hitch wiring harness and module and can't get it to work.

I have added the +AHMU module to the VO but when I try to process car it fails with some warning about missing files. Not sure if there's a newer different daten file needed or what. I'm pretty sure I could figure this out but since I will never need to do this again I'd rather just pay someone to do it.
