So, I take my wife's Passat to VW for an oil change. When I call to inquire about final cost they say 40 something. The oil change is 30 something so I ask what they charged me. They said the changed a rear brake light for me. So I go and pick up the car and tell them I am not going to pay for the light cause I did not request for it to be changed. They say as a courtesy, they check all lights to make sure they are functioning correctly. I don't think it is a courtesy at all, looks like a way to miilk the customer out of a few bucks. I don't know much about cars but I can change most bulbs myself. Needless to say, they didn't charge me.
