Your car can Say A A1 A2 or B B1 B2 or count down ABCDEFG ect, however dealers roatate back and forth between A and B services so it prob had a B service at its 20K so yet another A service would or should be due around 30K miles on your car since its first at 10K was an A and 20k was a B.
Always thought the services just counted up A1 A2 B0 B1 B2....etc....thanks for clarification.
