E92 M3 cold start bouncing RPM

[Fearzzy]

During cold starts my idle have slowly been getting worse of the past few months, the RPM seem to bounce alot for a few seconds (sometimes worse than others, video is the avg). Recently it's also started to make this ticking noise that can be heard in the video, if that narrows down the diagnosis. It only happens during the first start of the day, and is basically unnoticable when the car has any heat leftover from the last drive. I also tried holding the throttle one time during the cold start (just 1200 rpm or as close as i could), but as soon as i let it go it just started bouncing again as if i just postponed it. Not sure if i should check the ICV etc. first as theres no fault codes given

Hi, look at mine thread: https://www.m3post.com/forums/showthread.php?t=1959589

In my case it was the ICV.

I had this the first couple of years. Did nothing and it eventually disappeared by itself, weird.
