Service on 2010 Mercedes GLK 350
1 Answer
It's an "A" service, plus additional work. I haven't gotten a clear answer from anywhere as to exactly what the extra letter means, but it may be some sort of guide as to time to be expected. Check the maint. book for more detail, but my guess is the the minder hasn't been reset properly, as "N" would indicate several hours of additional work. Sorry to be obtuse, but this issue always comes up and I have yet to find a straightforward explanation
