BMW E28 ECU Up for sale is a Working, in excellent condition BMW ECU. Bosch Part number-- 0 281 001 018 (0281001018). This ECU is for 85-86 BMW 524TD's, and is a VERY uncommon item. As always, check your ECU's part number to be sure this is the right one for you. 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.
