Alfa 156 2.4 JTD 2003 - Error Code P0235
I have got my free copy of Multiecuscan and lead now and plugs it all in, and I had the above error that wasn't shown on the generic software I had.
From looking online people have suggest MAP sensor or stuck open EGR valve.
The EGR valve is new, but also blanked off.
The MAP sensor is new - also proper expensive ALFA one.
When the car was in the garage recently they apparently checked all the pipe and no leaks, I assume they are correct.
Do anyone have a sugestion on where to look next? It might be my imagination but but I am sure I can hear the "suck/blow" of the turbo more than I used to. But then I could only be hearing it and I am looking/listening for issues.
I get a MSCF warning when I hit around 3k RPM in 4th and 5th and also in the lower gears it doesn't seem as strong as it used it, definatley a few flat spots.
Any help or points gratefully received.
