Hi, My A4 2.0Tfsi went to the dealers today for it's 1st AVS service with 18.5k on the clock - They called me mid morning and said that the air filter needed to be replaced at a cost of £44 - Why would such an item not be included on the standard service ? ? Or are they just trying their luck - I was in a mad rush when they called so said "yes" but should I argue the toss tomorrow when I pick it up. They quoted me £272 for the service when I booked but this is now going to be nearer £316 !!!!
