jaycraven94 Posted December 2, 2019 Share Posted December 2, 2019 Hi everyone. Can anyone help please? I'm having trouble with the coolant temperature of the car not reaching 90 degrees.. I have recently noticed that my car takes a very long time to warm up, it will only hit 90 degrees if going up a hill for a long time, but if i drive across the flat or down a hill, it will drop its temperature to around 50 degrees very quick (a mile or two). I have also noticed that its using a lot more fuel recently, and if i switch the climate control completely off, it will warm up normaly, but drop back down within a few minutes of turning it back on. I have had the thermostat changed and still no joy! Might be worth mentioning that its a 62 plate 2.0 TDI A5. If anyone has got any suggestions to identify my problem either mechanically or with VCDS ill be very greatfull, thank you Quote Link to comment Share on other sites More sharing options...
Magnet Posted December 3, 2019 Share Posted December 3, 2019 Hello Jay from the Homeland, Until I read down to ‘....had thermostat changed...’ this was pointing to a a barn door thermostat issue. What else could It be? Before we move on Jay, was the replacement a VAG or aftermarket make? Kind regards, Gareth. Quote Link to comment Share on other sites More sharing options...
