CDV (Clutch delay valve) delete mod

[Six6siX]

Saw this linked to the other day and been reading around as I have been jumping around slightly on the odd occasion from 1st and 2nd gear.

Has anyone here done this and felt any benefit - also advantages/disadvantages? I know there is a lot of info on other forums but thought I'd ask here for anyones 1st hand experience.

Its something I'm looking to do along with the exhaust flap mod.

(inb4 learn to drive etc )

I'd imagine it does what it says on the tin?

These are there to try and stop it being jump, so I'm not sure how far removing it would be.

Well from what I understand they delay the clutch engaging (slipping it effectively) by restricting the flow of fluid to try and give a smoother movement. But many have found, myself included tha it causes the judder and jerky gear changes as it makes the clutch action unpredictable compared to a 'normal' clutch.

People who have removed them say that starts from 1st and gear changes are much smoother without the valve but could put potential extra strain on the drive train if you dump the clutch at high rpm (which is pretty unlikely tbh.. )

And also increase the life of the clutch as there is much less slippage.

But I'm in two minds whether to just suck it up and try and get used to it or just remove it - hence wanting people's experiences.

It seems to be these purely to annoy people.

You mean the valve is an annoyance?

My car is currently having the CDV modified......will report back

Interested to hear your view post-mod!

I think on some models you can have it removed entirely as the pipes are flexible and so easy to manouver to compensate for the missing valve but some are not so easy to bend which requires modifying one for a better fit.

There is a guy/trader on one of the US forums I think who sells the modified PCVs for about $35, says they arent drilled out (as this damages the ends and could cause leaks) but uses a different method...or something like that.

edit:

Got my CDV removed on my old 320i E46. Was a massive improvement

Excellent to hear, have you had any issues related to removal? How do you find the gear changes and 1st gear moving off in comparison?
