Mercedes A-Class ECU & Air Mass Meter rebuild.
This ECU is a very common problem for the Mercedes A-Class, causes fault codes blaming the air mass/ flow meter and can cause poor idle speed and/or rough running.
Own Unit Rebuild
We are now rebuilding customers own units with a Lifetime unlimited mileage warranty*.
These ECU / AFM are very expensive from the main dealer - we can rebuild your own ECU for a fraction of the price from the dealer and we give a longer warranty than buying a new unit.
When we rebuild your unit we program all of the adaptation values before we send it back, therefore you will not need to have any programming or adjustment work done after fitting your unit back to the vehicle.
Common faults include:
Air Mass/Flow Meter fault codes
Rough or erratic idle speed
Flat spots & hesitations
P0100 and/or P0170 Fault codes
This rebuild comes with a Lifetime unlimited mileage warranty*.
We have rebuilt thousands of these units for both Mercedes main dealers and independent specialists for years now so you can be assured of our very high standard of work.
Posting in your ECU for rebuild:
