how many of u have removed the CDV? i've read about people removing the clutch delay valve but i'm not sure what the pros & cons are. will the car drive better? will it do any harm to do car by removing it?

I was thinking about having it done before I took delivery on my car but a mechanic suggested that I drive the car first and then decide if there was some problem I was trying to correct. I don't drag race my car and honestly don't the ability to do very rapid shifts so have seen no useful reason in the world to do it.

Many of the former 4um fellas were sans CDV. For many, the CDV creates an artificially long delay in clutch engagement which throws off your natural sense of timing. The CDV does not affect disengagement. I removed my CDV and repacled it with the 'gutless' version from Zechaussen Racing. You don't need to replace it, you can simply remove it. But the Zechausen one retains the factory look. For me, this (along with the ZHP Short Shift Knob) produced a much improved experience.

The other thing that greatly improved my shifting was learning to pre-load the shiftlever while still under power.

Done it on my 06 3.0i....would do it again in a heartbeat.

Once you get the hang of it...it's not an issue. At least not for me. It's just like learning any other stick. Just takes some practice and patience.

[BimmerZealot]

But then when you drive a non-BMW aren't you messed up all over again? Makes more sense to go with the general consensus right?

[Dammmittt]

Wait...you drive other cars? CHEATER

[jadam]

I put the modified one in.

[sixspeed]

Modified CDV here also - could tell the difference within 3.5 seconds (or however long it takes to get up to speed in 1st... )

[BimmerZealot]

Ordered mine, cant wait to get it and install it. I'll let you guys know the results of it.

Bimmerzealot-Who are you having install the CDV? I also live in sd and have the exact same car as you, but its a coupe. I want to do the same, so let me know.

As an FYI, it's literally a 15 minute DIY...

As another FYI, don't try to have this done at the dealer. I'm sure it's not "warranty compatible".

[BimmerZealot]

My buddy works at a local car shop he is helping me with the install. It seems like a pretty straightforward DIY and shouldn't be that hard. I've just never bled the fluid lines so I'm going to leave it to him because he does work like this on a regular basis.

Been giving mucho thought to the modified CDV, just too much going on right now however to get to it.

[Dammmittt]

I think I'm so used to the CDV now that if I changed it...it would throw me off. I'm so silky smooth I dunno how I could go without...

[BimmerZealot]

Got it done today, one word WOW. It's like night and day no more chatter backing out of the driveway or starting in 1st. 1st to 2nd is way easier to do now with much less jerkiness. I now have to re-learn how to drive my car (any manual car) now that I have the delete. Before I had to let the clutch out super early and also wait till it engaged before I could give it gas. Now I can modulate the gas/clutch like a normal stick shift. Totally recommend it to anyone that is considering doing it, worth every penny. Also for any of you wondering how hard it is to do, it is a very simple job, with bleeding the clutch probably took right around one hour, I picked up 350 mL of Dot 4 BMW Brake Fluid from the dealer at 4$ for one bottle.

I have a Cdv sitting on my desk, too lazy to install........

[BimmerZealot]

With the right tools it takes almost no time at all, it's very simple and straightforward.

Jack up the car, put it on a jackstand, I didn't even need to use two I just jacked one side up and it was plenty of room. Remove the metal cover that isn't directly covering the CDV but it gets in the way of the job. Clamp the rubber tubing that comes FROM the brake fluid reservoir, unbolt the CDV from the metal line that leads to the master cylinder, the master cylinder line is a 11MM use a flare wrench to hold it, and then a 17MM to unscrew the CDV. Install the new CDV screw it back onto the metal line, bleed clutch. Done

It threw me off at first because before with the CDV I was so use to letting the clutch out as soon as I got into gear because the delay meant I'd have to wait for the actual engagement to occur. So now with the CDV delete if I drive the same way the car will essentially mini launch now I have to drive it like a normal manual car and ease it into the engagement rather then "dropping" the clutch.

Did it. Preferred it.
