The dealer does skip some of the works in FSS A and B service. For example, my spare tire was 10 PSI lower after my last visit. The dealer should have performed all the inspection listed in the service booklet. That makes me wonder "how much" inspection was done. Perhaps MB issued a new service guideline to exclude inspection of spare tire.
I still go to the dealer for A and B service. I have the MB extended warranty. I don't want give them any reason for not covering any claim because of lack of maintenance. However after the warranty, I will be doing all the maintenance work.
