tr BMW ABS ECU Up for sale is a Working, in excellent condition BMW ABS Control Unit. Bosch part # 0 265 103 004, bmw part # 74204398. This ECU should fit: E30 *1984 - 1991 318 325 *1987 325I 4 DOOR 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. At this price buy it and throw it on the shelf if you plan to drive one of these fine cars for a while. I only sell the OEM units, never aftermarket so they are the same quality as your original. Thanks for looking!
