mine worked out like this:
service labour 127.93
oil filter 7.99
pollen filter 13.57
washer 0.33
oil 82.80
-------------------
£232.62
plus vat on all of that: £40.71
£273.33
But included wash, good new courtesy car (new A4) for a day
I had a price of £230 from Ed at APS in Northampton which is an experienced independent that i would be happy to use, but by the time i factored in the convenience of the loan car and distance, the price from Audi locally is not too bad.
Also the applied some software fixes, including slightly incredibly a fix for a judder on the clutch- the clutch control unit, which even more remarkably seems to have made a big improvement. No doubt this would not be available from most independents.
If you are getting your own oil you need to make sure it is long life Audi approved as otherwise you have to go to 9,000 mile services or risk the warranty being invalidated.
