ECM/ECU Re-programming 2000 E 320 4-Matic Wagon

[coventryhall]

My independent MB Specialist has diagnosed a bad ECM for my 2000 E 320 4-Matic Wagon. Cylinders 4 & 5 are not firing (no spark) and working backwards all indications point to the ECM. He also stated that no codes are being generated. My questions are: 1) Are authorized MB Dealers the only source to program or reprogram the ECM? 2) Can the ECM be programmed with-out taking the car to the dealer? 3) How much does it cost to re-program the ECM (the ECM is $200 from a used parts supplier)? 4) My wife has my truck while her car is broken and I want it back. Thanks for any suggestions.

does your indie have a star diagnose system? That is the main tool required and if he's small time, chances are he doesn't have it. Make sure you purchase a new BLANK ECU as these have to be married to the car.

Don't waste the $200 on a used control unit. It's irreversibly locked to the car.
