Yeah, I think the fuel economy has taken a hit, although it's hard to say for sure. What was the 'drift compensation' part about on your BMW?

I never really understood what "drift compensation" meant exactly, but it was something to do with the fuel injectors needing to be recalibrated, or something. In the end, one of my injectors was faulty. I'd get it checked out by a professional, sounds like you might have the same issue.

Thanks for the info! Turns out you were spot on. Took it to the shop, and it was a faulty injector. Repair cost me 515€. Runs like a dream now, though!

Hey, that sounds familiar! I had a similar issue with my old BMW, a real pain. Rough running and the check engine light drove me nuts. Is it affecting your fuel economy?
