Boost sensor didn't sort it...

...after cleaning it.

I've been having a problem where the cooling fan light, and the spanner light comes on. When it does this the engine sounds somewhat harsh, and at idle hunts badly between 100-1000 rpm (like, vroooom...vrooom...vrooom, constant revving sort of thing)

To replicate this problem, all you have to do is unplug the wiring loom that has the boost sensor & oil temp sensor on it (unplug the entire loom) and try to start it...it will do the same.

I have cleaned up the boost sensor, which was very mucky. However the problem has just started again.

What I want to know is, what else is run from that loom, as obviously it is something on there.

EDIT :: It's a 2001 2.0 DTi

Have you also posted this in the 'Engine & Drivetrain' section ?

[Big Sig]

Or checked that the fans work as they should?

D_D : No I haven't. I thought the diesel section would be most appropriate? Should I post there too?

B_S : Yup.

When these "episodes" happen, i lose the rev counter also.

If its doing it on idle sounds like it could be the air flow meter at fault. Probably best to get someone to read the codes for you
