I've posted on this subject many, many times before. I even contacted VDO about it specifically - they denied a problem with the gauges and blame it on the sending unit. Every Mercedes I've ever owned has had this problem - from all the feedback about it, it seems to be a very common problem. From a 1971 250 sedan to my present 300E. I think the basic design of their sending units has remained the same and hence the recurring problem. You'd think the engineers that designed such fine cars could fookin' design something as simple and crucial as a fuel gauge properly!!!!
Very annoying problem.
Hell, every old and dying P.O.S. American rustbucket we have sitting up at our family's farm has a perfectly accurate fuel gauge. Even our 1967 Chevy truck has a steady fuel gauge...
Get on it Mercedes!!!!
