We've just had the missus car done at Stafford VW, and to be honest the people there are really good and friendly. They don't like complaints so will pay attention to you to make sure it's done right, as long as you don't go in there demanding the world.
Best option is to give them a ring and see what they offer. Courtesy car, bit of discount etc. I would stick with VW for now if you have a FVWSH but if not, then a recognised garage can still maintain the FSH of the car with their stamp and you don't incur the cost of VW labour.
