I hope you're right. It's a big risk though.

Keep the old part and switch it back if you have a problem?

Well it's not going to completely void your whole entire warranty.
From what I understand it's only problems that may have been caused by the CDV, or whatever mod you did the car.

I'll have to consider it then.

I knew I joined this board for a reason - this is really great information! I too thought for some reason I just can't shift my E46 smoothly, especially between 1st and 2nd. But I thought it was my car, and not typical of all BMW's, and was hoping that my new car would not have the problem.

Some members have already replaced the CDV and have had good things to say.. I think it was wish1 that did it.

I'm ordering a mod CDV and will probably install stainless steel brake lines all at the same time....since they need to bleed the brakes anyway....thoughts?

Is there any futher feedback from somebody that has installed the modified CDV?

Hi Guys,

I have a UK E90 manual 318d and was wondering if I have a CDV too, or is it limited to petrol/larger engines?

Thanks

I HATED the CDV and did not enjoy driving my car. It was so jerky from 1st to 2nd. I had the modified CDV done a month after I got my car and it's a new car. The shfting is SMOOOOOTH as butter.

The best mod for the car and only cost $100 - http://www.zeckhausen.com/CDV.htm - that's where you get the modified CDV. $35 for CDV - $65 for the machanic.

Most people just remove / delete the CDV. But I choose to have it modified to look like OEM just in case BMW looks there. Although It's rare that BMW will need to look down there.

Just gave mine a test, and it seems to me that my car responds differently to a slow gentle clutch lift opposed to a swift release, therefore maybe the 318d doesn't have a CDV!

The only risk involved is that if you have a clutch or even trans problem, the dealer "may" void that portion of the warranty.
However, if you do the mod and you do have a trans problem, you should probably put the valve back in before going to get the trans looked at.

Also, if you know how a manual trans and the valve works, there isn't a reason why removing would cause any damage.
The valve is there to slow down the fluid to make for "smoother" shifts for those who can't drive manual properly to begin with.
I HATE it. I know how to modulate my clutch for smooth to aggressive action. The valve simply interfers with proper clutch operation in my view.

To E90Fleet.
In the US that mod can't void the whole warranty.
It can possibly void the clutch portion or even trans portion, but the manufacturer has to show that the problem being fixed was the result of the modification.

i think there was somebody on this board who did an update after doing the CDV mod install. at first he thought it was a better shift but after a month or so he said it felt pretty much the same. (with the 1-2nd shift). id do a search now but im lazy...
