2005 645ci with dual back boxes fitted
I need some advice please-my 6er simply is a nightmare to start in the COLD weather mornings, in fact I have to engage the 'cold start' simply to fire it up for the first time that day. If I then drive to warm and leave it for an hour it will splutter for at least a dozen times before it fires up again after keying for a bit!! then no probs, no stalling, no revs up n down...drives fine, itís driving me nuts, it's almost as though it does not reach the correct revs before dying on me in the cold. Any ideas- only one we can suggest is cam sensor???
