BMW 135i – CDV Delete & Oil Change

Since Memorial Day is on Monday, I decided to take advantage of the long weekend and do some maintenance on the car. She was due for an oil change so I picked up 7 quarts of Castrol Edge, fully synthetic 5W-30. I also stopped at the dealership and picked up an oil filter kit.

I saw a few posts online about people deleting the Clutch Delay Valve for a better clutch feel. Since I was already underneath the car, I figured I might as well try removing this thing:

I popped out the locking pins with a small screwdriver and pulled the valve right out. I quickly capped both lines with my fingers because I didn’t want to lose any brake fluid. After that, I simply connected the lines back together without the valve in place. Then I got to work on bleeding the clutch. The whole process only took about a half hour with the help of a friend. Look how restrictive it is!

This car has the best clutch feel out of any car I’ve ever driven. The CVD delete paired with the BMW Performance short shift kit and the BMS clutch stop really makes for an awesome driving experience.

  1. Hello,

    I live in Appleton and I think I’ve seen you driving around a few times. I have a white 135, actually a friend of yours with a 4 series took a few pictures of my car and may have sent them to you.

    I’m considering doing a few of the mods you’ve done, currently the CDV delete and then probably a tune and dp in the future. I was wondering if we could meet up sometime, I’d really like to see how some of these mods have changed the car before I end up purchasing them.

    Also I have the 2011 linear springs and koni yellow dampers with wider Michelin pss’s, if your curious to see how those mods affect the car. My biggest gripe initially was how unstable the car felt going over bumps at speed, and these changes have made the car feel much more planted and comfortable.

    Let me know if you’d be willing to meet up sometime.

    Thanks,
    Blake

    1. Hey Blake,

      My friend did tell me about you. He said your car was really clean.

      I just sent you an email with my contact information. Hopefully we can meet up!
