Purchased this x5 few weeks ago had no issues with it. I've been having some issues with smoke sometimes blowing out of the left exhaust pipe. And also while parked on idle for over 5 mins when pulling off there will be a cloud a smoke left behind. Car has great service history on carfax from same bmw dealer. Service due light just came on recently. Has 109k miles. Last service was done at 100k shows on carfax.

Anybody has any opinions on what I should do or service. Or anybody with knowledge on replacing the valve seals my buddy tells me that's most likely what it is. Thanks
