Hello , i bought an audi a4 2014 2 month ago . When it’s cold outside -18 degree to -40 degree i got a light who say « Stop vehicule and check coolant level » . The problem is that message only appear when temperature are really cold , the coolant level are almost at the max. I’m from quebec so it’s that temperature 3-4 day a week. When it’s -10 degree outside the light didn’t appear . When it’s -20 degree outside and i put my car to the sun light , sometimes light don’t appear . It really seems to be a problem that appear with cold temperature . My car are Audi a4 2014 premium plus s-line . I really need help with this and i don’t know if i can still use the car . The temperature always stay at 190 and never go upper than that . I tryed to plug OBD2 and there is no code even if the coolant temp light are on . Sometimes light disapear while driving the car but it is rare . I really need help with this , if you guys have any question to help me solve that problem you can ask . Thank you for your help .
