He reset it but unfortunately it has come back on today. Has anybody got any ideas of what I could try?

It's too lean at idle, check for air leaks from the breather hoses close to the dip stick.

Mine came on yesterday - looks like my lambda sensor is away (from VAG Com) - will find out on Sat for sure.

Thanks.

I had a quick look at the breather pipe but couldn't hear any hiss. Had a quick feel but it was covered in crap so will have to have a better look at the weekend.

Cheers for the help.

Chris

Check out this thread, mine was the same and it was the breather hose under the inlet manifold, check out the pics and descriptions here.

Good Luck...............
