Sorry if this is a duplicate from the ECU forum. I couldn't find a way to move the thread.

Hi. Thought I'd post this after not being able to find a thread on this issue. My Ms3's cruise control experienced something weird recently. Occasionally when I turn on the engine the cruise control light would turn on by itself and stay in yellow. It's always on a cold day and usually happens when I start the car the first time that day. I can switch it off and I don't think it has affected my ability to use cruise control, but I'm curious and have no idea what caused it.

Any Ideas?
