Ayyyy! Don't confuse Rachel. Nanti she ask where's the choke button, and you answer: "Look in your iDrive", mine non-iDrive." 
Rachel, chokes disappeared from cars before you were born. That's when cars needed a 'warm up' after starting, before you release the choke and drive off.

faulty HPFP
U were right rastamarley bro
finally diagnosed the prob, its a faulty fuel pump. there is a loss of pressure after a while. so don't get a clean start until the pressure builds up again. getting a new one tomorrow.
so if u do hv long cranks and fluctuating rpm after an overnight there is something wrong !!! coz i never had it before. usually leave the car for a couple of days never start and never had such prob. always fires up instantly.
will know for sure once change tom!!! cheers

Unfortunately it not just a faulty fuel pump fuse... but glad to hear it's fixed now.
What was the mileage of the car when the fuel pump issue 1st occurred?

Wow... 9000 km only, what is up with their fuel pump supplier (VDO?) quality control!!
The cold start problem in my E34 case was just worn fuse issue giving intermittent connection when cold. Smooth start for 2+ more years with a new fuse before the pump totally KO one day. The E34 fuel pump lasted ~220,000KM. That's reliability and quality which is no longer around even since the E46.

I think after the start button is pushed its best to let the onbaord computer set in and fnish all diagnostics and startups before pressing the buttion again for ignition. It allows the system to set all parameters for proper functions and performance. always good practice to turn off all electricals before you shut the system down for a more propoer startup the next time. after ignition although no warm up is required give your car about 10 seconds to run before shifitng into gear and driving off. This is just good foreplay before having fun with the car. Since all off us see our beemers as our play thing anyway.

Hi bro... i am also facing the same problem with my 325 recently, but worst is, the engine dies off completely when i slowed down the car. imagine this... i had a few times engine died off while slow cornering and suddenly steering and brakes does't work anymore. with cars trailing behind me its very scary!!!
this normally happens during cold start. after i restart the engine, its ok... do you have the same experience?
did they managed to fix your problem?
