Hi everyone, I'm new to the forum and wondered if you could give me some advice please.

I have an Audi A3 TDI Sportback 2001 model and engine management system light has flashed and diagnostic test confirms EGR valve problem.

If I use diesel cleaning additives and higher rev driving can this help alleviate the problem and will garages clean them rather than replace them which looks like costing at least £600!

Trying really hard to avoid a big bill for my car which I have always been very happy with and still love it.

Also: will the light continue to flash until the diagnostic is reset even if the problem has been resolved?

Would really appreciate your help.

Thanks
Ed

 

flashing CEL = missfire

A bad EGR valve should cause a solid light not a flashing one (and some other issues, like rough idle, gas/diesel smell, etc).

I would start with a full scan and see what other codes you have stored. Your EGR might still end up being bad but it could be something else and I would hate to see you replace parts that don't need to be replaced at this time.
BTW £600 for this? Where did you go to get that kind of estimate? I see the part on ebay for under 100 which means you would be paying 500 in labor alone?
