I have a 63 plate Audi A3 2.0 Diesel S-Line, the other day whilst driving home I noticed a flashing light on my dashboard, but everything seemed fine, no loss of power or anything. It turns out to be the Diesel glow plug warning light. It's the first time I have seen this warning, and it didn't happen again for a couple of days until today it came on again. I took it to a garage where they ran a scan and the error code that is given is P2111- Throttle Actuator Control System Stuck Open. They had a look and unfortunately it doesn't seem like an easy job to get the damn thing out and look it over. They phoned up for a genuine Audi replacement just to get a price and they quoted me 281 +VAT. And then 2.5 hours labour on top so I'm looking at bill of around 600!!!! FML!

Has anyone else had similar issues? And does that quote for the part sound about right? In all fairness the garage did say it might end up that I don't need to replace the part, they will strip it out and inspect to see if it just needs a clean or if any of the wiring needs replacing.

Thanks in advance
Gary
