She, along with a few other service advisers, said only the catalytic converters, engine management sytstem, and a few other things were covered. Is there anyway you could post of send me a pic or scan of that specific page?

Hey Andrew, No problem, it's listed but they actually spell out the acronym and call it the mass air flow sensor, but it's in the 8 year 80k mile parts listed. There are a select few parts listed that apply to the California, Maine and Vermont cars but since you are in Mich. it should be covered. My warranty book is at home, but I can take a pic of the page and post it. I'd call back and have her check for a mass air flow sensor, it's there.

Intake Manifold Pressure: 10.9 in/HG
Intake Air Flow, MAF: 0.61 lb/min
Ignition Timing: -15.0 deg. BTC
Engine RPM: 537 to 549

I'll see if I can escape my wife's notice and get you the TB soon!! (In my house it is verbotten to spend money on anything other than shoes, boots, purses, lingerie or jeans and it is a capital offense soup up an AMG (assuming I have been forgiven for buying it in the first place)).

Update: I found a C55 throttle body at Potomac German Auto and am having it sent to Jeff to be bored out to fit the bored out elbow and MAF. The car has not stumbled in three weeks -- I still believe that by not properly snuging up all the various air delivery components I caused the stalling issues by creating a leak in the air intake system. Anyway, when I get the modified throttle body installed I will dyno the car and update everyone about the the benefits of these mods. Oh, with skinny winter tires 235 rear (235 front) my car can barely take off without spinning the rears -- my mods have overwhelmed its maximum winter traction on dry roads.

Also, I will research the federal emissions warranty covering the MAF.

Phil is correct. Please see p.37 (pic. 4, below) of the MB MY 2005 gasoline engine passenger car list of "Warranted Emission Related Components".

Wow thanks a lot Marc for the scans. I'm glad to see that it really does say "mass air flow sensor" there in print. There's no denying that once I show them. Should I call the service adviser back and tell him that it says it right in the manual that it should be covered?

I just looked at the PDF scans again and it says that the parts listed are only covered for 2 years/24,000 miles except for the parts with the stars next to them. Only the parts with the stars are covered for 8 years/80,000 miles.
