My temperature gaugee (which is the combo fuel gauge, and lube oil pressure gauge) is very speratic flipping around alot. I changed this whole gauge unit out, same thing with the replacement, Temp gauge bounces. A) next step (????) change out sensor at engine. ??? I am going to try this... is this the forward sensor or the after sensor on the left side of engine block. Has any one done this job is it in a "thermo well" or when I pull it does the sensor sit in the coolant and will leak. Any type of sealant when I screw it back in please Jimc answered your questions. Before you spend any money, I would like to reinforce making sure the connections are good. MB has a history of poor contact due to oxidation. Unplugging and replugging the sensor connection a couple times will probably fix your problem. On my 79 the sensor wiring passes through the connector on the glow plug relay and this is absolutely another connector that should be exercised! you will have to unbolt the glow plug relay from the fender to do this I think. Watch your gauge stabilize after doing this..
