Took the car to Audi yesterday they did try to tell me it was normal, however the technican who serviced the car was in and said he had only reset it to fixed servicing and not variable.
I'll see what happens when the computer comes back to life over the coming weeks.
my concern now is that if the technician who serviced it set it to fixed servicing he might have been under the impression that he carried out a "fixed service" although I was re-assured this was not the case I imagine ill be fobbed off again with some story if and when the service computer does start giving me information.
thanks again.
