A-Class ECU & Air Mass/Flow Meter

A-Class ECU and air mass fault

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*.

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 replacement unit.

 

Common Failure symptoms:

  • Air Mass/Flow Meter fault codes
  • Rough or erratic idle speed
  • High emissions
  • Poor MPG
  • Flat spots & hesitations

 

Common fault codes:

  • P0100 – mass air flow sensor
  • P0170 – self adaption too rich

 

Affected Vehicles:

  • 1st generation A-Class range (1997-2005)

 

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*
