Hi All,

I have a Golf Mk7 1.2 TSI from 2013, which
Started overheating. The gauge goes from 90 to 120-130 in just a few seconds and then goes back down as fast after staying there for a while. There's no pattern to it, it can happen after 3 hours of driving like after 4 minutes of standing still.
I have changed the water pump and Belt, there are no coolant leaks, I purged the coolant circuit and filled new coolant. I changed the radiator and the fan works just fine.
I'm afraid this could be the head gasket but I don't want to go down that road until I eliminate all other possibilities.

Thanks in advance for any help.
