New to the forum and new to Audi and require some help.
Car reaches temp fine after approx 2-3 mile (90 degrees) and sits there firm.
Heater blows cold all the time. Temp gauge shoots up to the red, alarm bells go off saying check coolant level and switch off engine.
Switch it off, turn it back on temp reads 90 degrees again, warning goes off, no loss of coolant at all.
Only had the car a week and it's already doing my head in (new heater motor/resistor, new ignition barrel, radio switches itself on and off, central locking playing up on key)
So a nice simple fix would be good before I decide it goes back to the dealer permanently.
