The warning couldn’t be more self-explanatory, however it’s amusing I get this today at -12C (10F) and not on the -30 days! First time I’ve seen the warning all winter.
Thanks for this detective CRVW. I did take four days of short (under 2 miles) trips under cold temperatures before the warning came on today. A longer drive this afternoon turned the warning off. I’ll see what happens tomorrow. Appreciate you finding the Audi info.
