2019 Volkswagon Tiguan
My digital speedometer stopped working, it usually shows 0 with a line through
it, but every once in awhile the speed will go up to 25 or 35. We recently went
through a cold spell where I am and the weather was -35 every day for a week.
Wondering if that has anything to do with it.
You probably turned on the avrg miles/galon instead of the speed. Try cycling through the menu to set it back to current speed.
