Mercedes ECU Up for sale is a Working, in excellent condition Mercedes ECU. Bosch Part number-- 0 280 800 316, mercedes part number-- 011 545 04 32 [07]. This ECU came out of a 1990 w124 chassis Mercedes 300e 2.6, should also fit some other 300e's and 300te's. May fit other models/years, but as always your best bet is to match the part number to the one on your ECU. This is one of the most common no start or random stalling problems with these cars. 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.
