I put mine in after sending two and then receiving one modified valve back from zeckhausen. I got my CDV's in Germany, but they can't be much more here in the states ... around 3 Euro each. So, for a total of around 10 bucks including shipping, it is the only way to go.
Shifting is much better and unless the dealer cuts apart the valve, no way they can tell. Regarding not using a valve, my e90 looked like it had enough slack to do it but did not want to risk the whole dealer issue. |

A couple of guys have said that they suspect the difference is really more psychological than anything. I'd like to get more opinions on this if anyone else cares to chime in....
Also, is not having one in the first place as good as having the modified one? It's so cheap that part of me wants to try it just for the hell of it even though I'm a little skeptical.

ressurection time
i got my car and ive turned the DTC off a few times for some fun, but it seems like either A: everyone on this forum lies and the traction is wonderfull, or B: im burning clutch like there is no tommarow (though im not getting any of that wonderfull smell) im guessing its B, but at the same time, i feel like its not, normally if a clutch is slipping it will rev way up and then drop down real fast, im not getting any of that, but the lack of any wheelspin what so ever is really disturbing (im not dropping the clutch but im going WOT in 1st the second i i feel its engaged) ive even waited for a bit at 1k to be absolutly sure and then floored it, same at 3k has everyone just WAY over-exagerated the lack of traction? the question: could it be that the CDV is forcing the clutch to slip all the way up until i shift, (note that the car is still accelerating like a rocket though) maybe the new tires just have a lot of traction and will lose a lot once they wear more?

I did it today with a friend, and we pump the break padel to let the air out. He step on both break and clutch when i open the bleeder valve. We did it couple times, and it is all good now. Now I feel I can drive manual car again :-) (over 10 years experiences with manual cars).

ordered my modified CDV today...
hope its as good as advertised without the CDV... will need help in removing the old one and installing the modified one. ANY SUGGESTIONS WOULD BE GREATLY APPRECIATED. cant do it myself cause i dont have a lift of any sort plus i am not too keen on mechanical stuff... liitle angle eye mod or the rear fog light mod ... no prob. but i am weary of removing the wrong pin or not bleeding correctly.

If you are going to remove the CDV, and do not have someone to help you or even if you do I would recommend buying a brake line vacuum bleeder, it works better then pumping the peddles and you do not get brake fluid all over the place. Remember brake fluid makes great pain remover. I have seen where people bleed brakes and with hands covered in fluid touch the cars paint. Leave a nice permanent hand mark in the paint.

And I didnt read the previous page, so I just n00bed myself by repeating what someone else did. Since next week is my vacation, I think I will stop down in NJ and pay a visit to them and buy a modified CDV. |

The CDV is held in place only by clips and no tools are required to remove/install a modified CDV other than a screwdriver to remove the panel that covers the location? The 7mm box wrench is used to bleed the clutch valve...turning the valve until air/fluid drips out?

Maybe air is getting back in somehow. Double check it one more time and try again. Sometimes you just need time to think things over before re-attacking.
