As a mechanic and mot tester I've never had much need to go to a garage before but I replaced the engine on my a3 after cambelt failure and needed the radio code so I thought, instead of mucking about, I'd pop to Audi.
I went to Guildford Audi as I dropped my wife off in the morning at her work which is local.
The guy was very helpful told me it would cost £15 for the code and would get the car a free health check and check any outstanding warranty items.
I agreed and he got me a coffee and a newspaper and off my car went.
Best £15 I ever spent he kept me informed at all times said that the coil packs were part of a recall and changed all 4 for nothing, got my radio code and the car washed and hoovered. Also got a new tax disc holder!
As having never once been on this side of the counter I have to say it's been made very pleasant and comfortable, good coffee too.
I'm not normally one for praising people least of all faceless corporations but this is the best customer service I have ever encountered and I would recommend a visit to Guildford Audi any time.
