Finally got around to changing out my MAF this weekend. It fixed my CEL. My Error codes were P0170 and P0173. The job took about 15 minutes and no tools.

In trying to confirm that this was the problem I bought the Mercedes Card for my Snap-On MT2500 Scanner. I hooked it up to the ODBII plug and it said that now I needed Snap-On Part # &%@#&* adapter and Mercedes Part # **@)#^ Plug for the underhood recepticle. At this point I said screw it and just installed the MAF and called it good.

I am still curious about how much more info is available via the MB cartridge vs ODBII. I guess I will have to find the adapter and plug.

i use vag-com to scan my vw's, but it can be used for any VAG (Volkswagen Audi Group) protocol, i.e. vw, audi, seat, skoda, etc...
i know for volkswagen/audi there is a way to jumper two pins on the scan port and the cel will blink in a certain order to give you the P codes. actually volkswagen/audi sells a little plug you put in the scan port and has the literature explaining how to read the P codes, but it takes a long time and is a pain. best thing to do is buy a set of workshop manuals that describe how to pull codes and the dtc list.i dont know of any mercedes software yet, but luckily i have k-jetronic, so all i need is a gas tester.
i'll try my vag-com on my parents s-class the next time im over there and see if it works, but i doubt it will. i'll let you know.

actually there is a way to test your maf. i dont have the info in front of me, but it's an ohm test that you can do with your multimeter. if you call up a bosch shop in your area they might even be willing to tell you how to do it, or check it for you. also, the next time you need a maf or bosch part check out ecs tuning. jack gets me all my bosch stuff, and you save a ton of money.

And replacing the MAF, as he was advised, seems to have done the trick. [:D]
