Hello.
I have a 2016 825i, 400 hours, had it about a year, lives in the middle of nowhere, so far no major rodent invasions. The thing usually starts and runs fine. Recently, it was fine during a chore run and then abruptly began to start in the following way, never again to start normally:
Starts with little cranking
Idles low, about 900rpm
Sounds like it's missing, starved for air or air/fuel mix issue, maybe on 2 of 3 cylinders.
Will seriously bog down or stall with any throttle (pushing on the gas.)
After about a minute or 90 seconds of this struggling, begins to idle normally (around 1100rpm) and sounds
like it's running properly, and then will allow acceleration and normal driving.
BUT if you shut it off, even when very warm, the whole nonsense to start it is repeated.
Sometimes I've been able to 'skip' this 'waiting' by (on the throttle body itself) opening up the throttle
very quickly over and over, to trick it into higher rpm until it sort of clears, but this wastes gas and probably
spews a bunch of unburned fuel all over. This doesn't always work either. One time yesterday, it wouldn't restart at all when very warm, until I waited for a bit; I was likely being impatient.
The system is pretty immaculate; the throttle body looks brand new inside. I've yet to pull the plugs, or get into tearing the fuel system apart. Pulling the air cleaner does nothing to help, nor does spraying CRC stuff into the throttle body.
The situation smells to me of dead sensor/haywire computer control. Don't get me started on that...
Thanks for your comments in advance,
