Hi there,
Can anyone tell me what is involved in disabling the Clutch Delay Valve on a 2008 Z4M Coupe please? Is it DIY?
Thanks for any help.

Very DIY, from the amount of members who have done it. Here's one of many YT videos of it - I'm sure there might be better ones out there

Strangely I couldn't find a 'How to' on this forum, only one about modifying it rather than replacing it...?

I have a 2003 2.5 and removed mine about 5 years ago.
The job itself is very easy, unbolt either end of the CDV, remove and then reconnect the parts you're left with. Bleed the clutch for a few pumps of the pedal (that's what I did) and you're done. It has been a number of years since I did mine, but I'm pretty sure that was all there was to it.
If you have a ramp, it's a 10 minute job. If not it's a bit of a PITA accessing it from under the car, awkward not difficult!
Good luck

Thanks Enzed and Lance. Looks like my delay valve is coming off. I learned to live with it but don't like it. I'm sure it will be better removed. I can get it on a hoist so should be straightforward.

The following is from an old post when I did mine -
A ramp or pit would be perfect, if not, lift from passenger side (UK spec car) remove front wheel, only for extra space and stand placement. Get under car between wheel and jacking point, CDV is sort of directly under the front of the passenger seat, next to the gearbox.
It really is a very straight forward job, but do pinch the clutch hose otherwise it will pi55 fluid.
IIRC, 11mm and 17mm open ended to loosen and remove the CDV which actually sits in little bracket thingy, undo the smaller end first and it'll just spin off by hand. Same spanners to connect the ends you are left with.

It's a must to do it! A clutch which you have control of!
I clamped the hose and then just undid the CDV at both ends and reconnected the line, then took the clamp off and gave the pedal a couple of pumps, my son's girlfriend tried it and guess what my next job was? Same thing done on hers and no need to bleed either system, very easy and well worthwhile if you like a faster gear change.

Done mine over the weekend and noticed the difference. I did drive my 1998 E36 Compact in between though so not sure if that made it feel even better!
Worth doing!
