A-Class ECU & Air Mass/Flow Meter
Mercedes A-Class ECU & Air Mass Meter rebuild.
This ECU is a very common problem for the Mercedes A-Class, which causes fault codes blaming the air mass/ flow meter and can cause poor idle speed and/or rough running.
Internal malfunction of this ECU & combined air mass meter will also cause starting problems and high emissions when it does eventually run.
We are now rebuilding customers own units with a Lifetime unlimited mileage warranty*.

How To Test a Mass Air Flow Sensor
Test and rebuild:
Each Mercedes A-Class ECU and air mass/flow meter is tested using our HIL (Hardware In-the-Loop) testing rigs. We put these ECUs under real-world load and driving conditions on every test. Using only higher rated than standard components we ensure that the rebuilt ECU will outlast the vehicle it is installed back onto.
Programming:
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.
Quality:
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.
Warranty:
Lifetime unlimited mileage*
