I've not seen boiling points given for CHF11S or the newer CHF202 (which supersedes 11S).

That being said, I've never had a problem with the 11S or 202 boiling over at the track.

bringing back old thread, does anybody know if the system self bleeds any air out ? or is there a process? I recently changed mine and I can hear a noise when i turn the wheel all the way to either side. I was thinking maybe caught some air in the system.

Me too bringing back an old thread. I had the same issue as the OP and was low on power steering fluid. Added some to top off and the noise went away. My whining sound would come when turning left hard and last night I turned left hard and the sound stayed for a while even when parked or going straight. Today topped off power steering fluid, went for a drive and made hard right/left turns and no sound!

Just wanted to update everyone, hope it helps!

I hear a sound too when turning the wheel ALL the way but it goes away once you release it just a bit from max wheel turn. Hope this helps, not sure how loud your sound is?

I want to flush and refill on ps fluid, however, i see two types of ch11s, one is ch11s synthetic and one is just ch11s. I cannot find any differentiation on any of the forums. Anyone know which is correct for e9x m3, ch11s or ch11s synthetic?
