Does anyone know why it does this? To confirm - A/C was NOT on at the time. Neither were any electronics except the radio and fan blower on minimum setting. (No heated seats or rear windscreen or headlights/sidelights/wipers etc were on.)
Could it be that my battery is getting low and the car is trying to put extra charge into it? Or could it just be the cold weather? It was just below freezing today... (Car idles at 800rpms even when it's almost at full operating temp though.)

I bet you have DCT, right? There is a SW update to fix idle issues and trans gear selection issues for the DCT.
