Tutorial: Clutch Delay Valve Removal. (Manual Cars)


Recommended Posts

This is just a quick guide on how to remove the restriction in the standard Golf R/GTI clutch setup.

The restrictor ring is found inside the bleeder block located under the air intake setup.

 

As standard this causes a fluid restriction through the unit which is there to dampen clutch engagement and soften clutch operation, leaving a wooly and slightly numb & delayed characteristic which is favored by the average driver. For those who want a sportier  more direct driving experience, the unrestricted fluid passage after restrictor removal results in, faster, firmer clutch engagement and disengagement.

 

This does not completely remove the 'lag' that can be felt when doing high rev rapid shifts from 3-4, 4-5 & 5-6 but does go some way to improving it. In all other circumstances clutch operation and power engagement is vastly improved.

 

The location of the restriction is directly below the intake setup and to the right of the block.

The piece you are looking for looks like this:

It is located here:

And closer in:

(Revo Intake Setup)

You will need to remove the airbox and intake pipe on the standard setup in order to access it. With the REVO setup and some others you can get away with just removing the filter to gain enough access.

 

Next you will need to simply pry up the two metal clips. 1 on each side arrowed here:

You use a small thin flat blade screwdriver to lever them up and they will pop up and unlock. They don't need to be removed completely.

 

Once they are up, its ready to be removed. You need to get ready with some rags to mop up/catch the clutch fluid that will come out when you remove the bleed block. There isn't much. When ready you simply pull the tube from the right hand side and then pull the bleeder from the block. It isn't tight and comes out easily.

 

You then have this:

The actual restriction is a small spinning ring of yellow plastic inside of the unit.

As you can see from this side:

And the other side:

Now the way i used to remove this is to poke a small enough flat blade screwdriver down one side of the unit to forceably break the restriction until it comes out in pieces. I had to apply quite a bit of pressure to do this. I then rinsed it throughly under the tap to ensure there was no debris remaining.

 

Once done, it should look like this:

And thats it!

Make sure you dry it off properly and then reattach to the block and pipe. Push down the clips to lock, and then bleed the air out of the clutch lines and you're done!

 

Good luck!

You can get it out without removing the entire assembly. BUT if you bobble just a bit you are removing the whole thing to fish it out of the assembly as it can be dislodged the wrong way fairly easily

To get it out without breaking it just remove the bleeder screw. That's what holds it in place. To reinstall it, you'd need to just carefully pop it back in - maybe use a wire to keep it aligned as you settle it back in - and then reinstall the bleeder valve.

 

Some folks have started running a drill bit through the block to open it up in the same manner as the ECS Clutch Bleeder Block. I went ahead and just installed the ECS version - wish I could get rid of all the el cheapo plastic parts.

 

When you reinstall don't forget you have to bleed the clutch - 5 ish presses on the clutch pedal with the bleeder screw cracked about 1/8 turn do the trick. And if you have the ECS it's a speed bleeder so it can be done without helpers. You'll need DOT 4 (in the US; not sure what it's called elsewhere) brake fluid to top up the reservoir.

Hello. Long time lurker here.

Great thread. Looking at the modification, if you just want to remove the yellow plastic disc thing, would it be possible just to remove the the bleeder screw and pull it out through there or even remove the larger nut (15mm maybe) below the bleeder screw and then pull it out? This would mean you wouldn't have to disconnect it either end and so not lose so much fluid= less mess and less bleeding afterwards.

Just wanted to add my bit to removing the clutch delay thingy.

Before taking it out my whinge was that it was difficult to change smoothly AND quickly especially going from 1st to 2nd and 2nd to 3rd, I tried to figure out what was going on and worked out that when releasing the clutch rapidly the clutch plate was slowed down just a bit by the fluid restriction but my left foot was telling my right foot to give more throttle just as it's done for years.

Problem was that left foot was telling right foot to get to work before the clutch was fully engaged to flywheel. Result, lumpy changes.

 

The faster I banged the clutch out, the bigger the delay between clutch pedal being fully up and clutch being fully engaged.

 

Release clutch s-l-o-w-l-y and no problem because your left foot is keeping pace with the speed at which the fluid restriction will allow the clutch to move towards the flywheel.

 

So whipped the little yellow thing out and bled the clutch.

 

Drove the car out the garage and instantly noticed the difference. Clutch is lighter ('cos no fluid restriction) and my left and right feet are back on the same wavelength. No more lumpy changes from traffic lights.

 

Why do VW do it?

Beats me in a car like the R but apparently it's to make gear changes smoother. Maybe as a nod to people who don't have much experience with manuals; is Americans or to make you drive slower :grin: .

 

Bottom line IMO best no cost mod you can make to the car.

On the plus side there is no need to force out the valve! Simply release the metal C clip under the bleeder screw, pull the bleed screw fully out and the yellow delay valve will now fall out. Check the O ring and refit the bleed screw.

I also tested putting the yellow delay valve back in and it's a doddle!

 

I would definitely recommend for anyone looking for a bit more clutch feel and if you don't like it, you can always but it back!

      All,
       
      I recently had the clutch replaced on my VW Golf R 2015,  Xtreme Clutch, I have done just over 1000kms and it has started slipping again.
      The oil indicator light also came on at the same time. There are no visible sign of a leak.
       
      Are these related?

      I've have a (2012 Volkswagen Golf R 4 Cylinders F 2.0L MFI Turbo DOHC)(MK6 Golf R) that I've been having some serious clutch issues with. It's Stage 2+ with a turbo-back exhaust, upgraded Powercore intake, Haldex controller, and custom tune (350hp). With this much power, the original owner put in a FX400 8-puck ceramic clutch kit and lightweight flywheel (single mass).

      I had the misfortune of the slave cylinder failing 7 months ago, which got fluid on the clutch disk and caused it to slip. After contacting CM and following their guidelines, the clutch was cleaned and the flywheel was resurfaced. I prayed this was the end of the clutch issues (since clutch slips in VWs are something way too common for me ) but a week ago I had a slip in 6th, then 5th, and finally 4th.

      I've read online that the FX400 only lasts 20k miles on average. I daily my Golf R and seldom get the chance to track it. Though I'm sure this is one of the most common threads seen on this forum, I wanted to ask for suggestions on a new clutch kit and flywheel. I want to have something that's reliable and good for a daily driver while still being fun and performance-based. I'd say I'm on a tight budget, but I'm willing to put out the extra penny for something that is quality and won't fail.

      Thanks for the help guys

      Hi lads, seen a post a while back with regards to the RTS and didn't look like anyone had tried one. 
       
      I currently have the Sachs sintered and was looking for anyone with first hand knowledge if these two are any friendlier? Thinking of a swap.
       
      Does the helix judder or squeal and is it as on off as the Sachs?
       
      Anyone with first hand knowledge of both?
       
      Cheers

      Hi guys,
      New to the forum and I have had my (totaly stock) Golf R for just under a month. Looking at making my first mods. I’m adding a Racingline Filter to the stock filter box and having a Res deleted. I have a Manual so I’m unsure as to what difference it will make to the sound?
      My question is, will I see a noticeable difference in the sound of the car? Also will it add a few more pops and bangs? I know the DSG it makes a big difference but not sure what the difference on a manual will be.
      Thanks.
