Today is around 20 degrees, very cold. 2006 300i auto, 38k miles now. I turned on the engine and it started slow, I guess it's the cold weather. After it warmed up for 1 min, the SERVICE ENGINE SOON light is on in yellow. The car also felt alittle jerky while rolling at 5m/h(automatic). When I put the car in reverse, the jerkyness was slightly more noticeable. This is the first time I have this problem.
I checked under the hood, I also noticed the Green labeled CAP, CHF1(powersteering?) fluid still has a slight leak since the last visit to the dealer(months ago). Does this have anything to do with it?

What could have caused this? I m planning to make an appointment with the dealer soon.

thanks
