Lumpy at ~ 1800 RPM only
I've previously had EGR and associated pipes and cooler all replaced/repaired under warranty, that was all about 6k miles ago.
Present issue is lumpy running at around 1800 - 2000 rpm, car is fine throughout the rest of the range including up top. It sprang up a MAF warning (P0101 and P014C) last week. I have replaced it but same issue is present, I cant find any leak in the inlet hose and the air filter is good. Do I need to disconnect battery for 10 minuntes or so to reset ECU now that I have a new MAF? I want to get access to throttle body next to remove and clean it up, is it possible to access without engine removal...? I can get by with engines but I ain't a mechanic and would'nt have access to a hoist etc. It's a V60 2014 D4. Really enjoy the car but finding this frustrating... |

The turbo usually kicks in at 1750, so I would advise to see if you have any damage to the blades, maybe you have some missing ones and the pressure is not building up till it revs even higher. |

It's right around where the turbo is kicking in, unfortunately I can't get access to check this out myself. Could do without a trip to the dealers. Local mechanic can have a look. Thanks

For the record, this turned out to be an intercooler hose. Which one I don't yet know.
