There's a good thread in here about removing the instrument cluster...a search on it will bring it up. It also mentions how to make a tool to remove it.

I've had similar problems with gauges on my MBs (esp. fuel gauge) and have found that the cold solder joint in the back of the unit itself is usually a good suspect, esp. when a "tap" on the dashboard seems to fix the problem...
