This ECU came out of a Mercedes 300E . and should also fit W124 cars, 300E & 190 2.6 Models. May fit other models/years too, 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 causes of no start or random stalling problems with these jetronic ECU 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 chore. This unit offers a 30 day refund or replacement warranty.
