I almost believed the old posts about not needing to bleed the clutch.
I did this mod yesterday and bled the clutch. It took longer, but I am glad I did it. I use a clear plastic tube to collect the fluid into a sealed bag, mainly to prevent a mess. It also lets me see what has come out of the system. I had fluid, then 4 inches of air, a little more fluid, then 2 inches of air, then fluid. The tube has a similar internal diameter to the clutch line. That is a lot of air. Also, the shape of the hard line into the slave cylinder would almost guarantee that some of the air would rise into the slave cylinder. |

Got it. I just sent you one back! lol
Basically... I re-bled my CDV twice when doing the install. Then a week later I bled it again. Its very hard to get all the air out of the clutch system. Dack

First did the brakes cause I wanted to flush all old brake fluid and fill it with new stuff (Super Blue DOT4), it was time do that anyway, the car is getting close to 2 years old (from day of production). So we sucked the old fluid as much as possible, put the pressure bleader and new fluid, bled the brakes and when finished with them, installed the modified CDV and bled the clutch. All in all we needed just a liter of brake fluid, I was expecting 2! I am sure that we bled all four brakes as well as clutch pretty text book way and saw the new "blue" fluid bleeding, still just 1 liter. Both brakes and clutch seemed totally fine on the way back home. 1-2 shifts as well 2-1 or neutral to 1 progressed neatly but I can't call it night and day since I was always quite satisfied with the stock too. This little mod cures the vague/blurred feeling and lack of control which used to happen in lower gears especially when cold and in slow driving. Gear changing and clutch feeling reminds me my first BMW now ('97 318 ti) and I say it as a compliment since that car's gearbox and clutch were simply perfect; light, sweet and very neutral which mostly disappeared from newer BMWs later on.

Egads! Not again!

It's really simple. If the brake fluid is exposed to air (other than at the filler) then the lines need to be bled. In cars such as ours (and especially yours, over here in the M forum) why would you want to compromise your safety by taking even the slightest chance? It's a closed pressurized system and it needs to be closed and pressurized when you're done. Why the fuss about it? Rant Over
