engine light solid on

[madadam]

Hi. I'm a new owner of an Audi A6 quattro 2010. I've had it for a week now. After 200miles the CEL came on, stayed on for 3days and went off again,  now it's back on. I've cleaned the fuel cap sealing area. I'm waiting to hear back from a garage for diagnostic service on Wednesday, but are there any other reasons it may light. It's nearly at 125000miles. And the dvla website notifies me of an outstanding recall, which I'll arrange to have done, but I don't what it is.

I'll introduce myself in the newbie section.  thanks in advance, - I expect this question has been asked before. 😁

Welcome Adam,

The light could be as a result of numerous components, so it’s simply a guessing game prior to a diagnostic assessment. 
Re. Outstanding recall:- If it were mine, I would not (in caps) pursue this. It is possible that it was as a result of emission recalls, and this forum has been dotted with horror stories in the past, following actioning these recalls. 
Your car, but a definite DON’T DO IT from me. 
Please let us know how you get on with the diagnostic check.

Regards,

Gareth.

p.s. Did you buy this from a dealer? If so, you should have redress, but I would notify them by e-mail, otherwise they may wriggle out of it, on the basis that you have been fiddling with it without reference to them.

Thanks Gareth.  Got some money back from dealer, using the diagnostic report as evidence. Did a dpf cleaner run through the tank, it's not come on since, but there's numerous records on the obd of egr valve.

Dealer paying for 40% of valve replacement (plus cooler) as I've had only 2 events since I had it and they should have checked it before sale. I don't want to cause any more problems to engine and emissions system by ignoring it, so going ahead this Wednesday.
