What to look for in a MB fault code?
Look for problems in the operation of the instrument cluster and on-board computer. These systems share data with the engine, transmission and traction systems. Inspect the transmission housing and connection cables. SRS/Airbag- Has the car been in a collision, jumped a curb, been to the body shop (welded) or jump started.

What causes an ECU fault on a Mercedes a class?
Mercedes A Class ECU & Air Mass/Flow Meter This ECU is a very common fault for the Mercedes A Class, it causes the engine management light to come on and fault code for the Air Mass/Flow Meter to be stored in the ECU’s memory. This fault can cause the engine to run rough and idle poorly.
