I have to agree with Ian, Harry.
I know you love all other aspects of the car and that trying to find the right A2 is increasingly difficult these days, especially if you want an approved used one.
However, if I were in your position, I'd be on to Audi UK and wanting much more than a bathrobe and a free service (which actually costs Audi about an hours labour and the price of 4 litres of oil and a couple of filters).
Ultimately, it's your choice and if you are happy then that's what counts. If possible, and you decide to keep your car, then try to strike up a relationship with a dealer (not necessarily your local one, although that would be more convenient, obviously). Look at the service awards in this months Audi Driver mag, and it's clear to see that there are some very good, responive and responsible dealers out there. If there's one in your area, get to know them.
Whatever you do, I wish you well with your new A2, and welcome to the A2OC - if the dealer can't solve your problems, we possibly can!
Cheers,
Mike
