This is an interesting one. When my car went into the dealer for its leaking roof and door rattle to be fixed it was indicating that it would need the A service at about 12000 miles. Since it came back (4+ weeks later) it has been indicating that it will need the B service at about the same mileage.
The car only did 50 or so miles whilst in their care so I'd assumed the Dealer reset something by mistake while they had the car (they've messed most other things up!!). I've asked them to explain the change but had no response yet.
