Motorraum: VANOS noise fixed.......but another problem.

Yes, you are probably right.

The air intake manifold gaskets were done at the same time as the PCV valve, and I checked for vacuum leaks by spraying brake cleaner all around the engine to see if there was a change in the idle........nothing.

When I tried to reset the adaptions there was a message saying "Module not responding". Even so, I have driven about 300 miles since the re-timing so I would have thought the DME would have learned the adaptions by now.

I wonder if there is a burnt valve or something?

Oh well, I'll keep trying to find what's wrong and will report back if I find anything.

Many thanks again for all your suggestions.
