My C200 Merc was first registered in September 1995. It has 97,000 miles on the clock and has always been regularly serviced. Last November 2 cylinders stopped working. We took the car to a small, reliable independent garage who services the vehicle and the trouble was located in the ECU. The ECU was repaired in a Lucas workshop at a cost of £325. At the same time the rear coil pack was replaced (this was as a precaution in case the coil had caused the ECU to fail), the wiring loom was inspected and found to be OK. 2 weeks ago exactly the same thing happened, the same 2 cylinders stopped working and the ECU was again found to be at fault. The unit was retuned to Lucas who fixed it free of charge.
When the ECU was refitted the engine worked OK but there was no signal to the idling motor. The ECU was once again returned to Lucas who identified that a non-replicable component had been damaged in the unit and they agreed to refund the initial charge of £325. I now need a brand new ECU fitted to the car. The garage has contacted MB and a new unit will cost about £1300 and is now on its way from Germany. When the garage contacted MB he was told that 74 of these ECU's had been replaced in the past year and there was 7 in stock in Germany. These numbers the garage considered to be high.
Could you tell me :-
1. Is there anything else that should be done to prevent a re-occurrence of the ECU failure because in all other respects the car is in good condition and there is no need to replace it at the moment?
2. Is there a record of ECU failures from MB cars of this age and type?
