Definitely a vacuum leak some where in the intake tract. Check all the hoses, remove air box and check the rubber hose by the fuel rail inlet.

 

Sometimes, the simpliest fixes are over looked. Just replace your gas cap!

 

ok i took the car mercedes specalist today and they run some tests and diagnose says its gas pedal censer, but they told me they not sure yet maybe there is another problem ,they will be done on Friday , i will let you guys know ,thnx for replay

 

looks like a simple vacuum leak....but the "stealer" looks like they are about to give it to u in a big way...hope u got vaseline...

 

I had a check engine light come on. I took it into an INDY shop and they told me MAS sensor was bad. So they reset and I was on my way. Later in the evening I gave the car a WOT pull and bling light appears again. When I pulled up into the drive way I opened the hood and heard a hissing sound coming from the rear driver side in the engine bay. Since it was dark and the car was hot I left it for the morning. First thing the next day I went back for a look where the hissing sound was coming from and Low and Behold a loose rubber tube. I connected it back to a steal tube that it got loose from, did the sneaky ecu reset...bingo light gone. I ended up buying a small clamp and that resolved the issue.

 

I thought the E55 don't use MAS?
