Hi All - first post here, as I have just become owner of my first mercedes, a 1993 300CE-24V in sportline guise (quite rare here in the UK)

Really pleased with it so far - there are a few small things that need sorting to bring it up to standard. one of these items is the temp gauge does not work.

Looking at the thermostat housing there are 3 possible sensors - looking from left to right there are :

large single pin sensor, smaller single pin sensor, and multi-pin connector.

which of these is possible culprit for temp gauge issue, and if not sensor is the gauge easily testable/repairable ?

many thanks for help

regards - Tb
