Mine went at the weekend. Took it to Audi today and the condenser has no gas in it and the air con is not working. Turns out a stone has damaged the radiator, same as others on here. It's remarkable they have such a huge gap where stones can get through. It's a design fault for sure. Awaiting the dealers reply to see if they will cover any of the cost for the repair. They have already said straight away its not covered by warranty so I've not got my hopes up. Will push for the work to be done FOC by Audi UK but if can't agree that with them then I'll be selling my car and ditching Audi completely. You can't charge £40k for a car and have something like this wrong with it. My concern is it goes again within a week it gets fixed. The cars only 6 month sold. How many times am I expected to shell out for the same repair during a 3 year ownership due to this design fault. Once a month, once a year, once a week!! It's not acceptable. I was going to order the new RS3 but if this isn't resolved sensibly then they forget it and I'll go an buy an A45 AMG instead. Not happy today.
