Service
Hi all I have a GL450 2012 with over 138,000 miles today. I went for an oil change and now I’m used to seeing service A,B or C. Now for next service it says Service G what does that mean? What does that entail? What’s the difference between each service? Thanks

if you still have your service booklet in the glove compartment, there is a matrix in there which describes what is done at each service.

I found the booklet for maintenance, but there’s no distinction between Service a Service B Service, D and Service G
