I've got an 225 S3 which I serviced at 49K on 21/03/2010, changed all the relevant parts with genuine audi items and the correct castol oil. I then reset the service display to what I thought was 8000 to next service.Now on 52,500 its saying service in 100 miles? Is this display calculated on time and number of hours driven aswell as miles. Its always warmed up and cooled down and as its done relatively little mileage in that year (second car) i'm unsure whether to service or not?
What do you guys think?
