Starting Issue
Discussion
I have an E85 3.0i with a FSH and 75k.
I went to use the car this morning (2.5 deg C) and it did not start. Turned over at the usual speed but did not catch. It sounded like it might occasionally. It started on the 3rd try and you could see the rev counter needle fluctuating slightly on fast idle.
It has since driven fine. I have used it recently in colder weather and started straight up as you wod expect.
Could this be a temp sensor not providing the info for a richer mixture or a crank position sensor?

The previous time you used the car did you by any chance start it, move it a short distance on the drive and then turn it off? BMW 6-pots love to flood if you do that - especially in winter. The mixture is very rich from the cold start and when you switch off raw fuel can lie in the cylinders. This also washes oil off the bores causing loss of compression and making the flooded engine even harder to start.
I got caught when I moved a car to wash it. Next day it was a devil to get started.

No, I am really OCD about that!
If any of the fleet is started from cold then they are driven until up to temperature before switching off. Makes the quick trip to the shop less than quick but rather that then have issues!
Thanks for the reply though as it may be the problem if someone else has an issue.

It really could be any number of things. My suggestion is get a code reader on it.I went to use the car this morning (2.5 deg C) and it did not start.
