It was a fuel evaporator valve or "mott "valve as they call it. Mercedes fixed it under warranty.
Also, there was some dead pixels in the display where the clock is. Mercedes replaced the entire instrument cluster. Under warranty!!wooohooo!!!!
They also fixed that funny sqeak in the steering wheel. All under warranty.
I figure my bill would have been $1200.00 easy, considering the instrument cluster alone is $1000.00 retail.
Even got a 2007 C280 4matic as a loaner.
