Is it normal for the cooling fans to be running when you've been driving the car normally? It's done this last couple of times i've driven the car. I know it does it when i've been pushing it hard but its not done it after just driving it normally It's like it has a DPF!
I get this with mine when have been driving in slow traffic, don’t think it’s anything to worry about.
My '97 Volvo S40 did this so it's nothing new. Every Audi I've had has done it since, although none as much as my 2.0 TDI A4 ;-)
