Progress in the midst of frustration. At least they found something. That's positive.
Its time to get mercedes corporate involved. And if you haven't already, i would email the dealership owner, general and service manager explaining the situation and asking for resolution for their faulty product. Sometimes the higher ups dont know whats happening at the ground level.Wednesday I sent the message to the head service writer whom I've dealt with pretty much since day one, and I was nice about it asking when would be a good time to bring in the car to have it looked at again , and I received a email back stating " I will talk with Jeff and Ed then reach back out to you." Apparently MB doesn't care that you drive a car that smells of gasoline, that could cause potential health hazards.... ( insert sarcasm) because I haven't heard back from them.
I think the more frustrating part is I bought the car from another dealership ( Lexus) but it had 19k on it(35k now) and well within warranty range, and so I asked the GM if this problem can't be fixed then this car is considered a Lemon at which time MB has to do something since you can't obviously repair my fuel vapor smell. His response was " Well, you would need to take it back to the dealership where you bought it from to ask for another car. So MB doesn't Honor Warranty?!?!?! I can't make this **** up. pardon my cussing but seriously enough is enough with all the junk.
