Good afternoon, I looking for some advice, I am the very proud owner of a 2015 B8 RS4 which i bought from my local Audi dealership. Love the car to bits whoever recently it seems to be smoking (white) whilst everyday driving. there is not plooms of it just wen your tottering about and certainly when you stop, even when the car is running at normal temperature. I always look for other cars to see if theirs are smoking due to the outside temperature, however theu never seem to be. Should i be worried ?
