My engine management light has come on and my car doesnt idle to good now. There seems to be pressure building up inside the engine as when i remove the dipstick it relieves some pressure and then the revs drop until i put the dipstick back in.
Any ideas?

It would be handy to know what model we are talking about.....e39? 525i ? 1998 ?
