Mercedes ECU Up for sale is a Working, in excellent condition Mercedes Engine fuel control module. Bosch Part number-- 0 261 203 242 (0261203242) , mercedes part number-- 016 545 57 32 ( 0165455732 ). This ECU came out of a 95 w124 chassis Mercedes e320. May fit other models/years, but as always your best bet is to match the part number to the one on your original ECU. These units now have to be special ordered from most dealers new for big $$ (often times several thousand bucks!), and finding a good one second hand is getting to be a very hard chore.
