Audi Tt Temperature Gauge Reading High

Audi tt 1 8 225 110k intermittent every other day or so temp needle going in to red zone and high temp warning symbol.

Audi tt temperature gauge reading high. Eg cruising along on the motorway 75 mph in cold weather the reading fluctuates above 90 to the next marker point. What is the normal temp reading for this weather when warmed up. Checked fans via radiator switch jumper both work hi and lo speed. It is about 85 90 degrees outside and after driving for a few miles the temperature gauge jumps to the shown position.

Ok so my temp gauge is fluctuating sometimes alot more then some it goes all the way up to overheat then goes back down to normal i just replaced thermo stat burped the radiator then a little bit ago it started fluctuating alot more and now when i get done driving it theres alot of antifreeze in the overflow tank and i can see that it comes out of the top of it to. There is no other indication that anything is wrong. 2006 onwards test and rebuild. Audi tt 1 8 3 2 years.
