380i 2000

Hi I've just bought a 380i 2000 reg. I have just drove about 100 miles in it and the engine light has come on. I've plugged it in to a code reader and it's saying p0170 fuel bank 1. It seems to be running fine. But the light keeps coming on after erasing it. Any ideas where to start?? thanks

Engine light probably came on because you have an 8.0l motor!

I take it you meant 328?
It's most likely a vacuum leak. Check this out, it has some good info related to that code.

As for places to start, check you intake boots for tears and rips. Have you ever replaced your CCV? If not is it original? The hoses connected to the CCV are common vacuum leak areas for old hoses.

Best bet is to get a smoke test done if you can't find anything obvious

Called a CCV, bit of a pain...

Note there are some difference with our older M52 engines.

VCG and Vanos info (I'd spend a long time sharpening your axe, if you know what I mean)

How do you know he has an M52 and not an M52TU?

I have the "TU" and the job wasn't that bad really, just time consuming. Though for those who aren't mechanically inclined I suppose it would be better to have someone do it for you.
