Hey

Any advice will be great

After 7 attempts of my car going back to the garage my temp gauge still seem to go into the red The garage have said they have replaced the sensor, even put in a brand new gauge, still it remains to go into the red, While driving the car this morning i noticed the car was warm inside (heater) even tho the dials where on the blue(cold) hmmmmm

thanks

Perhaps it actually is overheating, maybe a faulty stat I.E stuck closed one minute (The overheating) and open the next hence the gauge showing lower and heaters working?

by "dials in the blue" i presume you mean the heater control dial? This sounds like a classic example of the very common heater control valve (HCV) failure. They fail so often its untrue, and the last one that failed on me casued a blockage in the coolant flow - meaning overheated. It falls in line with what your saying too, as it controls the coolant flow into the heater matrix - so if it was messing around when ur telling it to be cold in the car it was opening and malking it hot in the car.....
