If it only happens with the AC on, try taking a look at the compressor. If it happens all the time, it may be the injectors... try adding injector cleaner and get back to us with the new mpg tankfuls! Hopefully that should improve slightly, more and more over time.

Other than that, it's great to see fuelly getting populated by Mercedes enthusiasts. Keep it up!
