Hi, Sorry about the late reply. If you haven't got it sorted yet can I check, when you say it blows faintly are you referring to the strength of the fans air flow or the heat temp? The Heat Sensor informs the Onboard Computer about the temp of the engine so it regulates fuel/oxygen mix etc whereas the thermostat just opens and closes to regulate the flow of water/coolant through the engine, depending on the water temp flowing through it. Is this of any use? Seán
Hi mate. My Mk5 1.4 blows hot air but faintly would the heat sensor be the problem? Also the temp sits at 90 doesn't over heat or anything like that
