Does anybody have any verdict for a lot of black smoke (way more than usual) and the orange engine light in the dash.
I got it remaped a few weeks ogo from 140 to 185,would that have anything to do with it ?.
The car still pulls great but when its up to about 70 it seems to pull back a bit,or miss fire ,something like that.
Thats the best way i can explane it.
Thanks in advance.....

I scanned the car and it showed up a MAF and an EGR fault.

The car had a panel filter in it which he had removed. I told him to clean the MAF with contact cleaner and see if the codes came back.

He got the EGR replaced last week but now the car is way down on power, he had another thread up about it yesterday.

mmmm , did you check boost request vs actual in block 11? vnt on the turbo could be stuck closed causing no boost , this would cause the black smoke as the engine management system is waiting for air mass

stick an airmass into it anyway , should be a service item
