I don't want to start a new thread on this topic.

Can someone please confirm:

My engine went into limp home a few weeks back on cold start, and it happened again the other day. Same codes as the first time that lead to Idle Control Valve.

I bought a new fuel breather valve, but decided against buying an idle control valve figuring I can clean it out.

Back in the day when I owned an e36 m3 some 12-15 years ago, this was also a common problem however the solution was cleaning it out with carb cleaner or soaking it in sea foam - I forgot which product it was exactly. But you could clean it out, which would typically resolve the issue.

For the e92 m3, I searched the codes I was getting and from what I found - everyone that has had this issue has replaced the entire ICV unit. Why not clean it? Does that not work or am I missing something? Obviously trying to avoid spending $800 if I don't have to.
