I did the CDV about two weeks ago. I honestly had a hard time discerning a difference at first (I may have had thick sole shoes for first drive). After driving it for two weeks, with two track days, it's become apparently smoother shifting between 1-2-3 and heel and toeing. I noticed I can feel disengagement through the pedal with thinner sole shoes.
I will say the install was mostly easy. I had a hell of a time bleeding the clutch, though, making baby turns on the bleeder valve due to limited access ( it may be easier with some sort of an angled wrench). The other thing that made it difficult was that one of the release clips on the connectors was facing towards the top of the vehicle rather than towards the ground. |

Take your old CDV and use a 3mm punch to knock out the restrictor from inside the original CDV. Once you remove the restrictor... install it back in the car and re-bleed your clutch. insert 3mm punch or a small thin screwdriver... and give it a WHACK! cdv with restrictor removed... Good Luck, Dack

Just joined the modified cdv club!
Honestly, I didn't know what to expect driving, but I thought this might result in harsher shifts with the added flow-ability in the clutch lines. Man, was I wrong. For me it's so much smoother driving the same way I did before now that the clutch is responding to me. Took way too long before I did this mod and the hour it took (mostly setting up) was well worth it. |

huh?
I feel like I am missing something. I don't experience any difficulty driving the car. I can't detect a lag in clutch engagement.
I don't notice a difference between my Nissan '04 and my 128, 2013 when I drive them back to back. When and how in driving would I experience this CDV problem? Has this problem been eliminated on the 2013? I don't like the hill holder thing-feels unnatural- but that's another story. |

It is most certainly NOT a placebo! That "thing" in my hand is the restrictor from the CDV.

If one were to attempt to learn English as a second language from this forum, one would conclude that the word "performance" when attached to a modification meant "change for the sake of change". That is not a bad thing, because if that were not so this forum would be long cold and there wouldn't be a fraternity tinkering with their cars for the joy of tinkering. I have to say that I miss the passing of Larryn from this forum. He provided a lot of wisdom and he was motivated by actual performance, tested at the track and at the autoslalom. With respect to this mod though, I suspect it is better only because it is different. Question: with the CDV installed how fast does one need to release the clutch before the slave cylinder can't track the pedal movement any more? Arthur1920 is saying "the king has no clothes". He is wrong about hill hold though - greatest thing since sliced bread! Great thing about this forum - we get to disagree about things. Of course I will agree that your version of the CDV delete is the best. If I get bored and decide to try it, I will do it your way. |

Clutch engages just as one would expect. I see where, based on the pictures of the CDV, it would slow down clutch movement. It makes sense and is probably a good thing to limit clutch wear, but i just dont feel it. I will have to look under there to see if it was modified prior to my taking ownership, but i dont think it was. Nothing on the car looked touched. Intake, DPs, exhaust and DME box were all virgin when i got it home.
Strange. It may be the stock throttle mapping that is a little laggy on light application, but when i changed to LT map on my Cobb, i just had to relearn quickly the feathering. Still doesnt feel laggy.

I removed the CDV on my '09 128i two days ago. Thanks to everyone for all the instructions and recommendations! The whole process was very straight-forward and, apart from a bit of time spent bleeding air from the clutch, everything went swimmingly.

After driving my 08'135 for over a year I finally decided to try the delete. It took me a while to find a wrench to bleed the clutch but I finally got it done, I can feel a difference but nothing outrageous

Hey guys ... need some help! I just put the new CDV delete valve in and while I was bleeding the system, I lost all clutch pressure. Isn't the clutch reservoir reservoir the same as the clutch? Did I miss something here?
So far I can't seem to get any pressure on the clutch pedal ... stuck. |

OK - Figured it out... The clutch pulls from the back portion of the reservoir and it fills from the top. So you need to really keep the reservoir filled to the top or the small section for the clutch will drain out as you bleed. I was getting a lot of air and had to bleed it a lot which is why I lost fluid.
Anyway - as everyone else has said ... OMFG!! What a great mod, such a difference and it drives normally now. Also, why is everyone complaining about bleeding the lines? It was so easy (apart from running out of fluid) and the bleeder is easily accessible. Easy mod! Thanks! |

The CDV delete is a great mod. Now you need to get the Performance SSK for the total 6MT effect! Enjoy, Dackel
