The service advisor responds "The manual is created for all BMW M cars and for your car you don't need to do it unless the car tells you to." Now I feel like i'm losing my sanity as I respond "Well just do it.." I didn't feel like going into the fact that the CBS does not tell you when your spark plug change is needed and it is clearly shown in the manual that it is not displayed on the CBS.
Am I dealing with inept people or am I being too harsh?
You aren't necessarily dealing with inept people nor are you being too harsh. BMW is inconsistent between models, and your adviser just isn't ultimately familiar with all of the S65's intricacies. Your frustration is justified. I got both stories from my adviser on two different visits.
