[spoiler]Hey guys, new here signed up just so I could post this. I’m having the common coolant control valve issues on my 2021 3. Problem is, I can’t get the cel to go off/code p0126 to trigger. I drive about 25 minutes to work each day back and forth, on the highway doing at least 60mph for at least 15 minutes. Temps near me recently dipped, around 35°F-40°F. This is the third commute in a row where the car has not reached operating temp and the gauge has stayed in the blue zone or right above it. Dealer doesn’t want to mess with it unless I have the code, though I experience every other symptom. How can I get the code to trigger? Is my commute not long enough? I have my heat set to 80°, will that play a factor in having the code trigger? Thank you.
