Hi everyone I am new to the VW world and I recently purchased an 05 GLI with 105000 miles and I've had it for about 3 weeks and now my temp gauge is really acting up. When I first start it up in the morning the temp gauge is just fine and rises correctly but if i park it when its at operating temp then get back in before it totally cools off and then shut it off again the needle sticks in random spots. Most recently it decided to stop just under the 190 mark and then i turned on the car and the needle raises from the 180ish point all the way to the hot hot mark and i know its not overheating and I have replaced the Coolant Temp Sensor with the green top. So is my gauge going bad or something else??
