I've got a 2001 (51) S3 on the long life service plan.
Has just done 53,000 miles, and had a service on 45,000 last December.
The computer is telling me it's another 10,000 miles to go before the next service. I had planned to get another service done in December, but that's only about another 1500 miles.
Is it "safe" just to go by what the car tells you as the service interval on the long life plan? I went to an S3 from an old TR7, so I'm still stuck in the "better safe than sorry attitude" towards servicing, but would rather not have to spend the money if I don't have to.
