I am now 100% sure that my MAF is acting up and throwing the P0170 code at me. The dealer told me that I have a manifold leak, which is highly unlikely. Do you think I can demand the MAF to be cleaned or replaced? My car is under warranty, 08 CLS63 with 30,000 miles on it...

What do you think? I hate when dealers just nitpick different parts in order to solve a problem.. They think replacing everything around the problem will solve it. I hate this trial and error approach....

There was a bulletin on the manifold leak should be replaced under service bulletin. I had mine done last year. CEL goes away. I think it was a manifold gasket that is faulty on the 63's

LOL! I would have done the same!

Thanks, for the info. My dealer actually did look at the MAF and replaced it, however, the leak is actually there. The part is coming in tomorrow, so I should be back on the road by Thursday for sure!
