I recently posted a thread on this topic with a response I received from VDO regarding fuel gauges on MBs. I'm convinced they have an inherent fault.

It's one thing, as Dennis mentioned, to have an asymmetrical tank which produces a non-linear reading past the 1/2 mark as the tank's shape and volume changes. That's all good and fine as long as the gauge is working properly.

The main problems with Mercedes is that the gauge seems to have a demented mind of its own past the 1/2 mark, as someguyfromMaryland put so well.

VDO of course denied any defect in their gauges.
