Start the engine, press and hold the trip reset button until the display shows "test 1". Release the button then immediately press again and keep pressing repeatedly until it shows "test 19", release the button. The display will alternate between "Log 1 -on" & "Log 1 -off". While it is showing "Log 1 -off" press the button and press repeatedly until it shows "7" then release the button. This will give a live and accurate reading of the coolant temperature.

OK, even more confused now. Ran the engine (stationary) up to about 80 degrees, then took it for a run. The temp then fluctuated between 97 and 104 degrees, averaging around 99.
Switched off and checked the top hose and it was rock hard. Left it for 6 hours then opened expansion tank. Slight hiss then nothing. No coolant left in tank though. Sniffed expansion tank and could smell petrol but not exhaust.
Like I said, I'm perplexed.
