Interestingly, my issues with cold starts (stalling, rough idle) seem to have went away last weekend. I got an oil change, put in some BMW fuel system cleaner (essentially rebranded Techron), and reset all my adaptations through the MHD app. It's been a week and a half with no issues.
When was your last oil change? What fuel do you use (I use Ontario Esso 93)? Perhaps it may have been some buildup in the fuel lines mixed with the cold weather.
