Audi 5000 Turbo ECU Up for sale is a Working, in excellent condition Audi 5000 turbo ECU. VW/Audi part number 035 905 383 N , MAC07A 383N . This ECU came out of a 85 Audi 5000-turbo, my list shows this should fit all 1984-1985 10 valve Turbo Audi 5000 models. However as always your best bet is to match the part numbers with the original. These are very hard to find! 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.
