AO Service
I got a pop up message indicating AO Service due in 21 days. I have only 25,000 miles on my '17 S550. I know A is a simple oil and filter change.....what does AO include? I saw one Internet site says it includes transmission fluid change. Do I really need new fluid at 25,000 miles. This is my fifth Benz and have never had this message before.

Don't see it being more than an oil change and checks. BTW 222 should be posting here: https://mbworld.org/forums/s-class-w222-178/

Sorry about the posting....ironically, I phoned customer care at MBZ and they told me they have no information on what the services include. I find it disturbing that someone paying for a car like this cannot get a straight and true answer on what the service includes from Mercedes. I called the dealer and they told me it is an A service with fluid check and service.....for $320. Don't mind spending the money IF I know what I am getting before hand. I just had new pads at 22,000 miles which I found a little earlier than my previous cars, but this is a heavy car and I know it takes more stopping power to come to a stop. I love the car, and again expect to pay to maintain, but just surprised at some of the little things coming along. Had never heard of AO service since I bought my first Mercedes in 1978.
