Engine probs Alpina B10 3.3 ltr

[nel]

Hiya people

Just visiting your forum to ask a question for a friend. He has an Alpina B10 3.3 and has repeated problems with engine management defaulting to "crawl home" mode. A specialist fixed it for a short time by replacing the throttle stepper motor (as I recall) and flashing the E-Prom with the Alpina map. It has now come back to haunt him again.

So is this a "standard" problem with a known fix or is his an unlucky rare failure? Much appreciated....

What did the diagnostics say then?

If it's defaulting, the ECU would have recognised and stored the fault.

The AMM used on the 3.3 can fail - I've already replaced mine once.

Don't know exactly what diagnostics said but he's already had 2 new throttle bodies - unfortunately this seems to be a temporary fix. Have surfed the Alpina OC site and found reference to another sensor that can cause problems on the camshaft. It's currently with a specialist so we'll see if they find a definitive fix - I was just fishing in case it was a well known syndrome.

Cheers.
