Cheers Beech. I already do that process :( I only ride one or two days a week- but so do most s1000 riders. I too am a believer in not using the kill-switch :)

Having the same issue intermittently with my bike, 2017 with 8000km. Took it to the dealer and they scanned it but couldn't find any issues, they reset the ECU adaptations to see if that would help.

Hi all, I've got a 2017 S1000R Sport - purchased new in December 2017, ~2,000 km. I pull clutch in and have in neutral to start, am using 98 RON fuel (as per the 2017 owners manual) and am getting the cold start issue. Bike fires up strong, then rpm drops and engine stalls. Until today had always remained running on second start, today it took 4 starts to stay running. Bike had latest firmware installed a couple of weeks ago when I first reported the issue. Dealer service seems unsure of cause or what else they can do - no error codes etc. Anyone had any luck with this as I'm heading into first winter with the bike and expecting issue will continue to get worse. Cheers.

Did this resetting of ECU adaptations work? Thanks

Yep it seems to have solved it, I have done 14,000km now and it hasn't happened since they reset the adaptations.

@ Matt

I'm in the same boat, 2017, 98 RON, would fire up, then cark it. Took it to the dealer and they updated the ECU, reset the adaptions, and it starts a bit better. I find if you pull the clutch in on a cold start that improves it slightly. If after going to the dealer, getting it updated and reset, etc, the problem continues, ask for a fuel pressure test. There have been some fuel pressure problems causing cold start issues, and that requires a new fuel pump under warranty - BMW is  aware of the issue.

I found the clutch in on startup made no difference for me. I wondered about a fueling issue but thought it would cause issues at other times and not just cold start. Is the issue re-occurring for you?

Yea still idling a bit too low, then slowly works its way up. It's either fuel pressure or poor mapping. I shall continue taking my bike to the dealer - over and over again. If it can't be resolved, then:

Have any of you tried switching from 98 to 95 RON? It worked for me, it starts up perfect every time since switching.

Yup, tried 95 RON and it does start better, but these Euro 4 bikes are tuned for 98, and the manual only recommends 98.
