I've a 2.0TDi C6A6, according to the service manual the the intervals are 19k or two years. When I bought the car it had 53k on and was service 12/6/15 it was serviced 10/5/16 at 63k then 4/2/17 at 74k and is not telling me it needs doing again at 81k. Is this right or is someone having my pants down and not properly resetting the service counter?

Surely a car that runs 95% of it's mileage in 6th gear on a motorway shouldn't need servicing THAT often and with such low mileage intervals.
