Audi 100 90 80 TCU TCM Trans Control Module 097 927 731 BC
VW Transmission ECU Up for sale is a Working, in excellent condition VW Automatic Transmission ECU. VW Part number 097 927 731 BC (097927731bc) 097927731 , the letter code is on the silver sticker on the metal part of the ECU. Not sure what this ECU is from, My list shows that it fits some VW vanagon, Audi 100 80 and 90 models. Your best bet is to match the part numbers with the part you need. These units now have to be special ordered from most dealers new for big $$ (often times over $1000!), and finding a good one second hand is getting to be a very hard chore. A faulty TCU can potentially cause a host of shifting issues that may appear as though it's a transmission issue, however it's just as likely that there is a computer issue.
