The sensor I'm talking about is a grey two-pin one that tells the engine ECU the coolant temperature. The coolant thermostat is different, non-electrical, and regulates flow through the radiator, it is in the same black plastic housing as the coolant temperature sensor on the side of the engine head.

I'm suggesting the grey one may be causing overfuelling if it is reporting a very low temperature.

Okay I will check both because I also had an overheating issue with an Octavia MK2 where the engine thermostat was not allowing proper coolant flow through the engine so the coolant was boiling out in the filler tank while the coolant temperature sensor was reporting a low temperature and failing to trigger the radiator fans.
