Anyone ever had luck sending a 93-94 afm off for a rebuild? I stumbled across a company called Bavarian Restoration that specializes in electronics service for BMWs. One of the things they advertise is rebuilding Bosch/Denso AFMs. I emailed them and they said they have done them for the 80 series. $315 shipped. Seems a little high but given that I’m striking out finding a used or reman unit, I may try them out and see what happens.
