Driving around in the old 300TDi D1 these past few days I just noticed that when I pull quickly left e.g.exiting side road, the temperature gauge drops to 0, then as the vehicle straightens out rapidly ascends to the middle of the gauge again.
There is also a slight dipping and then it pops back midway as you drive along.
The coolant is correctly to the middly of the expansion tank, I also popped out the radiator and thermostat housing plugs and there are no air gaps. The system is pressurising fine and Anti Freeze up to date.
The cable from the wiring loom looks good.
The engine is a healthy 120k with the pump turned up slightly.
I replaced the serpentine earlier in the year when I put a new alternator on.
In general the car doesn't do many miles these days, but as the 110 is off being fettled I am running it around at the moment
Any ideas?
