We have re-manufacturing services available for some Mercedes engine control units (ECU), 1996 and forward. Many verified part numbers are also in stock and ready-to-ship, including some that we cannot perform repair services on. If you've got the right diagnostic equipment to program the module, there's no need to wait for us to rebuild your unit.

  • HFM
  • ME 1.0
  • ME 2.0/2.1
  • ME 2.7/2.8
  • ME 9.7

NOTE: Siemens manufactured ECU's with part numbers beginning with 111 and 271 cannot be serviced at this time


Do the units come pre-programmed?
All of our re-manufactured units are unlocked to clear out the coding data left behind from the previous vehicle. Once a unit is unlocked it must be installed into the vehicle and then programmed using a factory tool or other equivalent. 

I don't have any diagnostic equipment, can you rebuild my ECM?
Maybe! If your ECU has an issue that we can rebuild when we return it to you it will retain the original VIN and coding information and you will simply plug it back into your vehicle and be on your way. Most water damaged or burned ECUs will not fall into this category though, so it ultimately depends on the issue(s) your ECU is having. 

Will you test the unit for me?
We offer bench testing for some ECU issues. Due to the complicated nature of how these units function, testing for things like misfires on the bench may not be possible depending on what type of unit you have. Before you send your unit in to be tested, please contact us and we will let you know what we can do to help. 

What kind of warranty do you offer?
Our re-manufactured parts come with a one-year warranty. See our policies page for full details.
