so i was checking the records on my mothers car, which has around 70-80000 miles and i couldnt find anything about the engine air filter being change

is this part of dealership A and B or C service

i know my car, e63 only gets A and B services, (oil change/cabin filter plus brake flush with B service) but i dont have a C , so i replace my own filters for engine

whats recommended for this car, the 5.5 NA engine, M273 i believe....Her car says its due for service c , shoiuld i just let the dealer do it or take care of filter myself, thanks

MB recommends every 40,000 miles/4 years whichever comes first. OEM part # 2730940404 see attachment for install.

got it ... will that be included in c service
