Saw this on eBay having read that it is a worthwhile upgrade so thought I would buy on to be fitted on my next service. Seems good value for money?

Hi Folks

Can anyone confirm please whether there is a difference in the hose required for Z3 2.2i (2002)? I've searched the other related threads about clutch hoses and am still uncertain

Despite the various arguments as to whether it does (or doesn't

) make a significant difference to the gear change action, I'm going to invoke the cosmetic argument that "it looks nicer"

So provided of course the hoses are a universal or compatible fit, I might as well do it at the same time as the fluid change (which is now due).

Thanks
Titan

Hi Soma

Earls said the hose should be the same across the model range.
I ordered one yesterday lunchtime and it arrived in the post this morning

I'm hoping to fit / get it fitted next week and will report progress back here on the forum.

Regards
Titian

The hose will fit both the regular and ///M versions, but there is something else to remember. One of the main reasons that the braided clutch hose help is that it removes a restriction BMW put in the hydrolic line to slow down clutch action. This was done to protect the drivetrain from people dropping the clutch at the local traffic lights grand prix. On the ///M this restriction is part of the hose. on a regaulr Z3 it is a seperate 'lock valve' installed on clutch line at the slave cylinder.

Item 21 here - http://www.realoem.com/bmw/showparts.do ... g=21&fg=10

Replacing just the hose will deliver an improvement, but removing the lock valve, often referred to as a "CDV Delete" makes more of a difference.

Pictures as promised

NOTE: This is Dot Com's 2002 model year 2.2i, not an "M"

However, the principles are the same. The Z3M's have the CDV incorporated within the pipe that is replaced rather than as a two-piece rubber hose and separate CDV as shown here.

1 Before - rubber hose

2 After - Stainless Braided Hose - £20

3 Configuration of Flex hose, CDV and Fixed pipe to Slave Cylinder - (Note this is not how it appears on OEM where the CDV is shown directly attached to the slave cylinder)

4 The older rubber hose and CDV after a dose of penetrating fluid

5 End result with CDV deleted

Verdict
The gear change is now much easier and distinclty less notchy. I also feel that the clutch action is lighter in terms of pedal pressure.
However, SWMBO (aka Dot Com) doesn't think so and wants to know what all the fuss is about..........

Many thanks to Simon for all the PMs and encouragement
Regards

Great pictures Titan, I did the same job on my S50 ZMR last weekend, it also made the clutch pedal alot less heavy. Couple of pictures, please excuse the quality (camera Phone)

Made a gizmo to keep the plunger held firmly in whilst the clutch was bled

I'm finally getting my fitted with new slave cylinder which had a slight leak. Will be able to test it out this weekend

I don't think the M has any kind of CDV fitted.

When I bled mine, I used an easi-bleed (tyre pressure) and compressed the slave cylinder by hand then undid the bleed nipple (yes it hurts a bit, not so much if you soften the arm digging in your hand with a rag!!).

AFAIK the whole pipe on the Ms becomes the CDV in that it has different size couplings at either end - see Simon's post above

Correct, the restriction is inside the hose on an ///M. See here - http://128.83.80.200/mcoupe/cdv.html

Oh my god

Firstly I have to say that I had the a new slave cylinder fitted as well as the new hose so not sure how much of an effect that has had but....

what a difference the car feels to drive. I was hoping to be able to notice some benefit but the clutch is sooooooooooo much smoother. I have only driven back about 5 miles in heavy traffic from the garage but I had a big grin on my face, from actually using my left foot (rather than my right!

)

The "holding" point feels so much easier to play with, my left calf is not aching and makes the whole car feel smoother.

My car has nearly 80k on the clock and the slave cylinder had a slight leak before replacement but if the difference is this noticible I really would recommend getting one. Cost me £20 for the part and approx £50 to get fitted at a specialist (actually cost me nothing to get fitted as I needed the slave cylinder replacing anyway and they charged me £0 extra).

To say I'm chuffed is an understatement.

Just need to see how it performs with an open road, oh dear icey tomorrow

Hello,

I'm having a slight issue with my Earls Braided clutch hose,

To be fair to Earl when I phone him and his mate Adam answered they said they would call back and indeed they did (twice) and offered a full refund.

I was delighted by their customer serivice.

In fact....

they search google for me and found this lot

http://www.uucmotorwerks.com/

who seem to see the product I need.

http://store.nexternal.com/shared/Store ... S=uuc&All=

Unfortunately my Clutch hose appears to be the same as the one in the link above and not the same as the one earls sent, maybe it is because mine is a left hand drive? I don't know.

Anyone off to the states soon and fancy picking me up a clutch hose?

Anyway if anyone else is struggling with their braided fitment please let me know as It's annoyed me!

Happy Zedding

Something wrong there because the same clutch hose is used on all M Roadstera and M Coupes for all engines types S50,S52 and S54 in USA, Europe and UK. The hose is also interchangeable with the standard Z3 hose as it has the same fittings and is of similar length.

I suspect Earls just supplied the werong part.

Si.

spurs fan in a coupe · Post by **spurs fan in a coupe** » Thu 06 Aug, 2009 17:36

I must admit that I was confued as everyone on here has said that the same hose fits all.

The problem was that one end on the existing hose didnt have a hew bolt on, the mechanic cautiously said that in the absence of a male end of the earls hose would probably cause an issue when the old one was removed.

I had a look and agreed that it didnt look like it would fit.

The one from UUC looks the right one.

The one earl sent was the same (as far as I can see) as the one shown earlier in the link, with the yellow earls plastic hoop.

The original hose should be female:female at both ends, the original hose does look disceiving; was the hose actually disconnecting off the car or just looked at?

oakley6691 · Post by **oakley6691** » Sat 05 Sep, 2009 14:26

Just done this hose change mod on my 2002 2.2i and have to say the difference in the gear change for 1st to 2nd is drasticly improved, this is probably one of the best mode you can do for a few quid and only took 20 mins to do (I used a lift).

Thanks alot for that Si. So would you say, i should just replace mine or get it modified as it states on the website. I would rather safe the money and time and just remove it. Would that be ok?

On a Z3 you can just remove it. Modding was really for cars still under waranty so the dealers didn't moan about midifications causing issues. I would replace the hose though as the CDV is really only half the problem. An old spongy hose is also an inhibitor to smooth gearchanges.

Naeem.m · Post by **Naeem.m** » Wed 09 Sep, 2009 10:12

Thats cool Si. I have ordered the earls braided hose so will have that fitted and the CDV removed. Got a quote from indy who i know and said he would do it for £25. which is pretty good.

Cheers for your help

I'm thinking of ordering the earls braided hose for my 2.8. I like to do as many jobs on the car as possible myself. Is it just a case of unbolting the old hose and installing the new hose then bleeding the clutch. Do I need to know any thing before I start

Cheers for any information

So..is this worth doing on the runt of the litter? The 1.9 M44 hehe. Or is this just for it's bigger 6 cylinder brothers?

Roadster22i · Post by **Roadster22i** » Sun 21 Mar, 2010 15:17

Just fitted braided clutch hose. It Does make shifts slightly smoother, the general drive is improved too. Worth £30 as it also makes you bleed your clutch. Gunson eazibleeder super useful.

Jonttt · Post by **Jonttt** » Sun 21 Mar, 2010 15:39

I've just had one delivered from Earls for my new ///M as it was such a good upgrade on my first above

On a recent fast road run you really noted the clutch feel deteriorate due to the OEM rubber hose

Holy thread resurrection...

I found this using the search but unsure if it's the most recent, at 4 year old I doubt it.

Since starting to use my Z3M I couldn't help but notice how heavy and low the clutch is on it, but reading here I'm starting to think a couple of things. Could it be, sitting for 13 years without use, the clutch may be needing bled? I replaced the discs and pads on it and mad sure I flushed the fluid through but made she I never let the reservoir run near empty.

The other thing is, the braided clutch like seems like a great modification. I will do this and then bleed the clutch. After SMG, maybe I've just got too lazy in my old age.
