Clutch Delay Valve(CDV) swap

shortseller · 02-01-2012, 08:08 AM

Looking to delete my CDV on my 2010 335i coupe but want to replace rather than stretch the line. I have searched and found the M3 CDV(#21522283914) is identical to the 335i CDV(#21526764872) except it does not have the restrictive valve inside. Is this correct? Anyone swapped these out and had any issues? Thanks.

Changed my cdv 20k miles ago. No issues at all. The clutch engagement it is a lot smoother.

Buy an aftermarket cdv. After you install the new cdv make sure you bleed the line.

It's been done before; you can use the M3 CDV which is half the cost of an aftermarket one.

Hi,

I swapped out my 335i e91 6mt to an M3 CDV and also fitted BMS clutch stop.

Much much better.

Worthwhile mod

Cheers,

Dave
