Audi 200 Turbo ECU Up for sale is a Working, in excellent condition Audi 200 ECU. VW/Audi part number 447 905 383 M , MAC15 . This ECU came out of a 90 Audi 200-turbo, my list shows this should fit all 1989-1991 10 valve Turbo Audi 200 models. However as always your best bet is to match the part numbers with the original. This is not an easy to find ECU, as this was a very expensive low production number car. These units now have to be special ordered from most dealers new for big $$ (often times over $2000!), and finding a good one second hand is nearly impossible.
