GLC Service Question
I am wondering given the CarFax details attached, what service (A or B) should I do next and at what mileage?
A and B services every 10K
At the end of the maintenance book, there are a few services by mileage and time:
Every two years regardless of miles you change brake fluid.
I don't remember trany service, I think its 60K
Every 100K coolant

MB recommends brake fluid at 2 year intervals, and that would also be due this fall. I will defer to you if you want to follow that schedule as it’s a bit conservative unless you live in a very humid place (brake fluid absorbs water from the air, so it doesn’t wear-out per se, but rather the increased water content is the reason for the change). I’ve tested mine in multiple cars with an electronic tester and it’s never exceeded 1% water content with 3 year change intervals (which is the cadence for our Acura, though BMW and MB recommend 2-year intervals).
