Has anyone changed out the CDV on the 135 yet?

I checked with my parts guy today and he says the 135 has the same CDV as the E90 - part no. 7674872 in case you are interested. I plan to but one from Zeckhausen tomorrow and put it in ASAP. Will let you know.

I did mine today. Car feels way better. I feel like I can drive again hahaha.

drmacole · 03-25-2008, 08:05 PM

Was it the exact same procedure as in the E90 DIY? Did you bleed the line and/or use a clamp? Did you replace it with a Zechanhauser(sp?) product or just take it out of the line?
Thx Mike

I replaced it with a modified valve from Riss Racing. We bled the clutch. Whole thing took about 10 minutes.

i did the cdv this past easter sunday with my bro using it from zeckhausen racing.

Can you just connect the two pipes together? Is there enough slack?

beyondriddick · 03-27-2008, 07:44 PM

Maybe a noob question but I need to know; wtf is CDV?

I believe they are talking about a clutch delay valve - it prevents you from engaging the clutch too quickly and potentially damaging the clutch/drive train.

larryn · 03-27-2008, 08:06 PM

I did mine this afternoon too. The pedal take up is much easier and the clutch seems to grab smoother now. You can also let it out quicker if you give it a bit of gas, which was slightly delayed before.

Can someone post a CDV-delete in the DIY threads please?

We have installation instructions with ever purchase of our modified CDV. Takes about 5 min. for the install. Its different that eliminating the CDV because dealers can see if the CDV is not there, but cannot tell the difference from the Riss Racing Modified or a stock CDV.

Adam - are those instructions specific to the 135i? i know that it is relatively identical to that of the 335i process - but having an apples to apples instruction would be best for first-timers.

BTW- i just placed an order with you for your modified CDV - didn't specify for 135i though.

Its in the same location. Instructions are universal for 135i/335i.

i'll +1 for posting instructions, they may come with the part, but some of us like to know what we are getting ourselves into BEFORE we order the parts.
