hello so I have a e30 with m30b34 so I guess it's best to post it in this section, well I have a little problem it's about -20 celcius in finland at the moment and its a bitch to get my m30 started, it will start after cranking it for ages and usually the battery runs out of charge before it will start. once it does start up it runs completely fine no problem whatsoever it will idle at high rpm for a while and eventuall drop to around 600. so any ideas where I should start checking? could it be that the cold start valve is working improperly? however the Cold start valve is put in a place that is almost impossible to get to without taking whole intake manifold off

Could be the cold start injector or that sensor that controls it. Here's a link to help with diagnosing

The Bentley manual also has good info
