BMW E30 / E34 ECU "Programa rebuilt" Up for sale is a Working, in excellent condition BMW E30 ECU. Bosch Part number-- 0 261 200 153 (0261200153), BMW part number 1714998 / 8840407. This unit is from a 325i and is in good working order. Rebuilt by programe about 4 years ago, never a control unit problem since. This may also work with other models/years but as usual check your part number to be sure it will work. 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.
