thanks for your reply, the car was 3 years old when i brought it, 2009 plate, Mercedes gave a limited costing warranty for the first year and I took out the Audi extended warranty last year, just for such thing! Audi warranty have offered to refund me the policy cost, how odd?? but I have declined this, I have taken this up with Audi UK and put in a formal complaint against the dealer.I did question them why they had not informed me at the service intervals that the gear box oil change had not been carried out and it is surly a reasonable expectation for them to have brought this to attention,they said their system is not computerised in this section so they would not have known, yet they did at the service at 36500?? I will be naming and shaming them shortly but I feel I should wait for Audi UK to respond to my complaint first then look to use another dealer in the future. As a by thought I have just found paper work from when i had the brakes changed 3 months after buying the car with 40500 on the clock and still no warning or mention of this then, again the same dealer.
