I'm thinking of buying a 1 or 2 year old S3.

Can some one give me an idea of servicing costs?

I can only get the servicing prices of Audis over 3 years old off their website.

Thanks in advance.

Hi, and welcome to the forum

As a rule of thumb, I would definitely advise taking the car back to the dealer for the first few services as they can carry out updates on the systems with software downloads from the manufacturers which you may get from some specialists but cost wise probably wouldn't be too dissimilar. After that, you fall into the 3 years + category and then you are free to choose where to go then.

I just got an S3, they told me that service at least once a year or every 10k or long life 19k they said if I do every year it's about £399 and naturally the longer life one will be more

Ouch!  thats rather a lot for a service....I would get a quote for fixed price servicing from some other dealers just to be sure thats not their own price

Of course you'll have to find somewhere prepared to write you a quote - I suspect most places these days will know why you're asking...
