My 1998 S320 seems to have a typical fuel gauge problem. That is when the tank is filled up, the needle shows as if it is 2-3 gallons short of full. It used to take about 220 miles before the needle reaches 1/2 mark but now it takes about 160 miles to do that.

I did a search on this forum and it looks like the fuel sender unit is bad. BUT when I tried to order this part from Fastlane or any other parts stores, there are NO fuel sender unit available for S320. I can see E320's fuel sender units available but it looks as if S320 doesn't have such units.

Any ideas?

Most of the later MB's have this fuel gauge level sensor problem including the 1998 S320. The part number is 140-542-19-17 & has replaced 4 different part numbers!! List is $ 226.

Great replies. Does Fastlane have this part? Research time again...

Thanks DOC
