Thanks Sally - much appreciated.
Hi I've posted on RS6.com. All the best with this. I sold the car to a fellow in Sydney who I think moved to Queensland. Audi Australia were very unhelpful in terms that they denied any knowledge whatsoever of a problem. I got it "fixed" to the best of my knowledge and sold it. Not many V8 RS6s came to Australia but the DRC is obviously a problem. I have a thing for the RS6, but would I buy any other Audi, an R8 for example, absolutely not given my shoddy customer service experience over the DRC. Sallyh
