I recently purchased my 11 E92 335XI CPO and have started to notice longer than usual crank times. The first one happened a week ago which I thought might be due to cold weather (28F), but I see/notice it happen more frequently now. Its 59F today and I am still getting longer initial cranks.
The first startup always takes longer, however if i turn the car off and back on the car starts up instantly. Waiting for 5 minutes and repeating resets the long/normal crank time cycle.
Before going to the dealer, I just wanted to be sure if it really looks like a problem? I am a little paranoid reading all the threads on the issue. Here are videos from two different days:
