I have an '09 Jetta. This is the first time I am owning, rather than leasing, a car. I’m at about 50k miles at 40k VW’s manual and the dealership service center recommends a servicing that includes spark plug changing and checking various systems. I called a local mechanic, that was highly rated on this site, who told me that he had never heard of changing spark plugs so soon and I shouldn’t do it until more like 80k miles.
So my question is do I follow what’s in the manual or place my car in the care of this highly rated local mechanic and follow his guidance?
Also, how vital is it to have them do checks on the various systems if I am not having any issues and no lights have come on the dash?
