about a week ago the visit workshop light came on for the airmatic. The car is also stuck at its highest level. I had left it out in the cold for a couple of days. After I realized that the S430 was almost as high as my ml320 I put it in the garage for 4 days. After it had plenty of time to warm up it still didnt go back to normal. I even unhooked the battery and let it sit over night. No fix, still the same code and 4X4 look! Please help They know me by first name at the mercedes dealer.

Believe it or not about a month ago I started smelling gas in the S430. I washed it and looked for leaks. nothing. The seam actually failed on the gas tank and started leaking gas into the trunk and back seat! $1680 later and now the air issue. im open for suggestions.

thanks,
