Default EGR Valve

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.

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?
