i get the red dash bord and showing my gas tank is open
did any body get this problen and any clue how to fix this stuff

 

You are probably missing a gas cap or have a bad gas cap. Soon you will get a check engine light. You need to replace a gas cap. Once you do, check engine light will go out...eventually. It seems to take 2 days before the light went out.

 

also check for disconnected hose such as the one going to purging valve.

it is the pressure sensor which detects it.

 

Same thing happened to me, have MB get you a new cap, that should fix, Pete
