MCSF after MAF replacement code 1238
I have a 156 1.9 JTDm 16V on a 54 plate.
The car was running badly.
While the garage had the car it flashed up a MCSF code 1238 air quantity above target value.
They changed the MAF and the car runs magic again . But the MCSF has come back with the same fault code. They have reset the code but it comes back again. The car continues to run fine but the MCSF keeps coming up. No other codes are stored except 1238.
The MAF was a genuine Alfa (Bosch) unit from a dealer. The battery was replaced 12 months ago.
The car goes back in Tuesday anybody got ant bright ideas ??
If only my boss knew my Company Car had been remapped.
