tr VW ECU Up for sale is a Working, in excellent condition Passat / Golf / Jetta ECU. VW/Audi part number 8A0 907 404 J (8A0907404J), Bosch part # 0 261 200 874 (0261200874) . This ECU came out of a 1994 16v 2.0l Passat, and should also fit other similar models/years. However, as always your best bet is to match the part numbers with the part you need. This is one of the most common no start or random stalling problems with these Bosch ECU's. If yours does not have this problem, keep an extra ECU in the trunk, you might some day be glad you did... 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.
