Well I'm 500 miles overdue, and that is going to be 1,000 by the end of the week. Due to the dealer booking me in for the wrong day this week I now have to take it elsewhere, and hope I can get it done this week. However, even though I've done 10,500 miles since the last service the service light hasn't come on, meaning that it was reset wrong the last time! So time-wise it won't be overdue as the light isn't on, but mileage-wise it will be.
