Any insight from anyone is greatly appreciated as I was told this is an $800 fix.
You will more than likely need to replace your CCV with the cold weather version and maybe have your VANOS checked. Those two have been common problems on M52 and M54 motors for awhile now. I had a similar issue with my E39 where it would stall and idle like crap until the engine reached operating temperature.
$800 sounds really steep. I have a good independent mechanic and I paid ~$450 for parts and labor.
