Mercedes ECU 0 280 002 014 Up for sale is a Working, in excellent condition Mercedes Engine Control Unit. Mercedes Part numbers listed at top, This unit has been rebuilt by BOSCH in it's lifetime. Not sure when but I don't think very recently - This should also interchange with cars that use the 0280002013 / 0 280 002 013 model control units 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. Looks clean internally with no signs of damage or corrosion. I will warranty this unit to function for 30 days after you receive it. This unit is originally out of a 1975 450SL (W107 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.
