"Check Engine: Bring to workshop" Engine Light On.

Thanks for the replies

I have a Durametric on the way - my view is that they are always sought after and keep their price pretty well.

I have a £10 OBD11 reader which isn't up to much but does it does indicate a 3 cylinder misfire.

I read somewhere that overfilling engine oil might cause a problem - well coincidentally I changed the oil only 100 miles before the incident and the level on the stick was right at the top of the range but the electronic level measure was one tick below the max level so I can't think it would be that.

When I spoke to the independent Porsche dealer he did mention it might be the O2 sensors amongst other things.

I hope the Durametric isn't too difficult to use and I will report back.
