Mercedes ECU Up for sale is a Working, in excellent condition Mercedes Engine Control Unit. Mercedes Part number-- 0 280 002 005 (0280002005), - While it is used, it spent most of the past 15 years sitting on a shelf in a climate controlled garage so it's not been used much since it came out of a crash damaged running car. This unit is originally out of a 1974 450sel (w116 chassis). My list shows this should fit many R107 / W107 & W116 cars (4.5 Liter) with D-Jetronic (450, and 280 models) Your best bet is to check the part number of the ECU you are trying to replace with this items part number to make sure they are the same. These antique D-Jet injection "Computers" have not been easy to find for years now, and this is a good functional one in what I could call physically "excellent" condition. You might not find one nicer for ANY price.
