Hi, I just got the blower replaced on my 2016 Audi A3, which fried the MMI unit, leading to no audio. (From my online research, this seems to be a not uncommon problem.)

I've purchased a used MMI unit, and can hear that the speakers humming now, but nothing else works.

I phoned my local Audi dealer who told me I need a garage with a VAGCOM unit to code the unit to my car. Is there anywhere that anyone might recommend? I'm in Dundee, Scotland, so something in the range of Aberdeen, Edinburgh or Glasgow would be ideal. Thank you very much.
