My C250 had an engine management light coming in. The mechanic said the fault code was the mass air Flow sensor so I had it Replaced.
The Light is still on. I noticed Another thread on this but no conclusion.
Any help greatly appreciated.

Never had to replay one yet. Get a proper diagnosis on a star system.

The issue was that the sensor needed calibrated. I guess they don’t come “set” and possibly differ for every engine management system (very slightly).
