Finally decided to post a question after reading hundreds of other answers on this site.
Bought my first beautiful alfa 156 a few months ago, however.........................
I randomly get a mcsf light when ever it feels like, there is no rhyme or reason to it, it general comes on then goes of, at will. when setting of from lights it will come on then with a bit of accleration it tends to clear, but occasionally it stay on and cannot be cleared (usually on a hot day if the car temperature is above 21 c).
I have taken off the egr and cleaned it out (it wasnt that dirty to be fair), no change, so thinking the egr was caput i blanked it off. Mcsf went away for about a day then its back.
I had AA out one day i was so fed it with it (it was a hot day so it wouldnt clear) the engineer said ecu was showing no errors he took egr apart and tested it .........apparently its ok. AA man reckons i need my air system cleaning?
I had a full service including air and fuel filter no change, mechanic did say my air filter was extremely dirty? suggested some high strength cleaner........how will stuff in my diesel clean air pipes?
So after going around in beautiful Alfa circles im at MAF sensor, i have disconnected it and engine is running no different, i do seem to have better pick up with no maf but mcsf is if nothing else more frequent now but still on and off.
Does anyone have any ideas?
P.s. When the AA man was out and the mcsf light stayed on the alfa was putting out black smoke with revs, which it also does if i have the mcsf on start up.
Need to get this sorted so no wether to buy a MAF or my beautiful Alfa tattoo
Any ideas would be greatly appreciated, thanks in advance x
