Up for sale is a Working, in excellent condition BMW E30 ECU. Bosch Part number-- 0 261 200 007 (0261200007) . This ECU should work with the following models: (83-87) E28 528e(82-87) E30 325, 325e This is one of the most common no start or random stalling problems with these Motronic 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.
