Re: Remove CDV
I echo Steve G's comments. I thought it was just me making a mess of going from 1st to 2nd.

Remove CDV
I've had CDV removed and changed gearbox oil to Redline MTL and Redlline ATF4 in a 50/50 mix as recommended by Opie Oils.
Vast improvement, do it, you won't regret it. Smoother, easier and nicer gear change, my mechanic who is into motorsport (Fords) was sceptical but agreed afterwards.

I'm glad I ran across this topic. Interested in doing anything to improve driving performance. New to the group and I'm really enjoying having this form to learn from. My 03 Z4 2.5 has become the new love of my life. You know you got it bad when you find excuses just to get in the car and drive anywhere.

Removed last night and at first wasn't too impressed as the car jumped forward when I raised the clutch. After a few minutes though I realised why people do it - you can essentially "feel" the clutch more now so you can launch it better.
I literally clamp the flexi hose, removed the CDV, reconnected it and drove away

Trouble is Mat, is slows down engagement of the clutch, masking the bite point and causing slippage that wears the clutch prematurely. Also when you are going for it, it hinders smooth changes.Machine monkey wrote: ↑Fri Apr 04, 2014 1:56 pm Ok i dont have a full grasp so this might not be 100% correct.
But my understanding the CDV is to prevent harsh and sudden shocks causing damage to the DMF. From surges of power from say the clutch being drooped or poor gear changes. Its sole purpose is to protect the DMF from shock.

I think that part is unnecessary as you can just discard the cdv & reconnect the hydraulic pipe without it?Boris wrote: ↑Sun Oct 22, 2017 4:36 pm Someone has cottoned onto this I've just seen this for sale https://www.zeckhausen.com/catalog/prod ... cts_id=273

Yep ditch the CDV and the sh***y dual mass go single mass if you want clutch feel.
