Removing the "Drift Prevention Device" BMW Never Told You About
Vložit
- čas přidán 9. 11. 2020
- This tiny little CDV BMW installs (especially on your e36 and e46) causes premature wear on your clutch and makes drifting a lot harder. Let's see how big of a difference it makes getting rid of this thing on my BMW e36 M3 and why you might want to do it too!

About your sliding around on the seat, a trick I learned at BMW performance driving school may help. After assuming your normal seat position with the shoulder belt fastened, move the seat back a small amount then give the shoulder belt a quick tug to lock it. Now, move your seat back to your normal driving position. You should now be comfortably locked onto your seat. This may take some practice to get it right but once perfected you will not slide much if at all when cornering or drifting.
Never thought about that wow great tip 🙏
Sickkk tip I’m on break rn practicing and holy shit it works I always though it was more of a safety feature but great tip on using to lock the strap just need to find a more tight position
You're a BMW performance driving school graduate? I'm a bit jelly.
If you have good bucket seats you won't move even without seat belts.
Thanks for sharing that, very cool. I think I'll be telling about that to just about everyone who ever comments on sliding on their seat.
The video actually just answered a 3 year question I've had. I never understood why my e36 is so sluggish when I drop the clutch fast.
Every normal E36 and E46 models have it, didn't know the US M3 has one though
Omfg, i just sold mine after 6 years of wondering wtf that was xD
@@boonamai8926 do yk if the e34 (specifically 530i) has this?
Clutch delay valve. My E46 has it removed. Makes a decent amount of difference. Still have the dual mass flywheel though.
prefer dmf over smf for dailying
@@BmwMe-uh9sy yes
Is the CDV why my e46 is sluggish taking off from a stop?
One of the first “mods” that should be done on a standard transmission e90 335i if you are tuned as well,
335 is open diff 🤨

@@koppp_ sure you can, if you really try
@@kaelanburke2097 fr 💀
I think it would be nice of you to show us some of the steps on doing these mods. Great content but you can help a lot of e36 owners by showing the process.
Then someone screws up their car and now CZcams will hold him liable for telling you it’s 100%. As a car guy figure it out yourself?
I don’t think that’s how it works. He already made a step-by-step vid on how to change your subframe/diff bushings.
Just say a disclaimer before starting the process.
Thats not how it works bro
@@itzfreakinjamie wtf bro, CZcams is full of info videos. Just dont be a dick and take knowledge with a grain of salt.
That thing is too clean to drift imo
I refuse to believe he actually drifts.

@@nvl2691 what’s the difference
@@professorfinesser6374 not sure if you're being sarcastic or not...
but driving a car smoothly and efficiently puts a lot, lot less strain on the drivetrain than drifting
Weird, I just did this to mine last week! Completely agree, I wish I had done it a long time ago. So much crisper, feels like more of a sports car than ever.
The biggest "drift prevention device" in my E36 right now is the open diff :)
On lookout for a lsd but damn its hard in vancouver
Weld it ! 😁
Welded diff intensifies
@@maxwell5428 I am definitely heavily considering that option
@@isaactourand2562 get a welded and retain the stock open diff. welded is great but open makes a better daily driver. they can be swapped over in 30-45 mins for when you wanna skid/be sensible
@@grapeeater4000 that's what I was thinking of doing, if I can't snag a lsd before the end of the year I'm going to to just weld a separate diff
For people watching that haven’t done it. You actually don’t need a delete you can just bypass the part completely. At least that’s the case on an e36
One end just threads into the other without any changes
Same with e46
@@Ihatebmws so you can just take it out and put the 2 hoses back together without putting a new part in between them?
Well a delete kinda means bypassing the part completely 🤷

Homie looking blitzed in the first minute lmao. Love your videos, just discovered you yesterday been binging em since!
Welcome to the channel man!
I Remember believing the valve was a mod bmw made for americans. So They Could shift manual as well 😂. Cant Remember where it came from.
Think you are right. I never have seen it on a German E36.
@@janschonfeld1494 They are on all e46. Except euro m3 i think. Removed them from several. But no need for adapter. Just remove the sandwiched plate and Connect straight to nipple. But origin is interresting.
E39 got them
Well I am from Germany and can tell my e39 has ist
My old e46 didn't
Fortunat never hat an e36 tho
You didn't need to replace it with the UUC one! You can just remove the old CDV and thread everything back together without it in-line
Yeah, I did that too. Better to not run one at all if you plan to drift the car. Although, I really don't think he should be drifting this pavement princess.
@@tyler70878 does e39 540i has the same thing? Have the manual 6 speed..
@@tanelviljaste2509 I have one too, what a coincidence lol
Yeah it does, I removed it
@@tyler70878 Thanks man. Wait my engine back from rebuild. Have to remove that thing then.
@@tyler70878 Its a great modification for any BMW, I did it in my stock E36 vert- much better clutch response.
This man slides that thing like there aren't some grippy boyz on there. Fucken legend
I’ve got a BMW X3 this was the first thing I did when I got it, trying to drive fast and just getting slip every gear change
BMW Engineers spend so many hours making the car safe and in one little step you completely bypass it! Well done.
His car isn’t for safety. It’s for fun.
The Orpheus tube is for smoother daily driving engagement for a beginner standard trans driver and to help keep from stalling. Its just a luxury car thing.. all you need to do is pull it and drill the hole out to the line diameter or inbetween if you would like a little give on engagement smoothness to help keep from breaking axles..
This car is f reliable(unbreakable), I got one with 200000km and I drive it as hard as you, and still no problem (I have it 6 years and now is at 290000km ),this car is a legend that don't need a movie to become
lol
I have an e36 have replaced both cv axles, valve cover gasket, both tire rods are coming out bc they are stuck.
@@siennaracing638 yes so what?
My 130i has the coolerworks shortshifter pro and the clutch delay valve delete done and 2 of the best mods I've ever done,saving for a quaiffe diff now,enjoy the channel very much
1st drift event is a 1 way trip in to the barriers. Dont run your primary car.
Idiotic to drift this car.
My first time seeing your channel.
That E36 is so goddamn clean. The Halo's are stunning.
My first car was a 328i E36 lemon with no traction control. Really learned how to drive and such a fun car.
Welcome to the channel 👍.
FYI people asking why BMW fitted it:
To reduce torque spikes that cause movement and acceleration of the rear subframe.
Many BMW's, mainly the E46, suffer from ripping the subframe from the chassis.
By smoothing the clutch, it reduces the torque spikes.
If you plan on removing it and go full BRRRtt, consider reeinforcing the subframe mounts on the chassis by welding fitting plates.
MIG welding works best. I'd avoid MAG or electrode welding.
Wish i'd deleted the BS "clutch delay" POS when i got the car, or serviced the trans, and here i waited till the master cylinder went. You don't need to buy anything to replace it with btw, it just sit's in-line with the hose, just remove it, and reconnect the soft line back to the hard line without it.
Wow where is that e36 T shirt from.
I removed the cdv on my e46 m3... Massive improvement
Yes where is that shirt from?
What e36 shirt?
Look for Petrol Passion on Instagram or Facebook for T-Shirts :)
Just recently found your channel. I have a built sr20 s14 but have contemplated selling it to get another bmw. I've had a few e36 but never an m3. I think with the right mods, a na m3 would be really satisfying.
Welcome to the channel man! Obviously I support the m3 idea haha
@@TreatsOnTheStreets what differential ratio are you running currently? If you haven't tried a 3.91 yet I highly recommend it. It completely transformed my e36 when I was drifting it.
Look forward for what's next with your build. I need to start uploading. I have 100s of hours of queued shots, just too lazy to edit 🤦♂️
I bet that would help a ton! It is just the stock 3.23
I wonder if there's one of those devices attached to the indicators too
Get a CG Lock for your seatbelt. Then you'll be able to lock your lap belt portion down super tight to keep you from sliding around in the seat.
Literally just done this on my e46 m3,, its supercharged at 500hp, had problems with snatching 2nd and third gear, it would just light the clutch up straight away :(
Was going to buy a new clutch but removed the CDV and saved myself £800!!! Clutch doesn't slip at all anymore and the 1st to second shift is amazing now!! 😍😍😍
Pretty much my same experience, except I don't have 500hp 🤣
@@TreatsOnTheStreets its made the car sooo much better to drive. Its a animal now. Have a look. @e46m3s on insta. 🤪
About 10 years too late for me, wish I had known about this in college.
My E46 six speed needs this now! well that and a decent shifter stock shift knob loves to fly off haha 😂
Mine does too
Mines does too
go zhp knob fcp euro
God, I always hated that slippage going from 1 to 2 on my old E36 M3... thought it was a worn clutch, should've done this mod!
you have literally the best sound on a bmw video. play this video through sub woofer equipped stereo and you can really appreciate this car. which is also sweet looking by the way well done
Thank you for this video. Drove my new to me M3/4/5 200 miles home last night and was not happy getting on the highway. Clutch slipped into 3rd and 4th, to the point that I let off. I was pissed, because the clutch is supposedly only been on there for 30k miles or so.
Then I started reading about this CDV.... yea, I tried and tried to get the clutch to slip on the highway in various gears with just throttle, no dice. Slow shifting, held solid.
But that is no way to drive a "motosport" car. I am coming from a 700hp B5 S4 (coming BACK to BMW now.) and granny shifting because of a factory nanny just won't cut it. But, I'll pass on double clutching.b
Today I do now e46 yes! Also, that E36 is so clean!!!
Hate to break it to you, but you can do this completely for free. Just take the valve out and connect the 2 lines together. The UUC piece wont hurt anything but its an extra point for it to leak at
I recognize those mountains!! come out to the may event, I'll be there, black convertible 328i
Or just drill out the original one 🤷♂️
Lol or just take it off and put the line directly to the other side
Can't believe people spend money on this "delete"
That e36 m3 is way too nice to take to event yo I would rather you take my 328i ive been working on than tear up the m3 yo lol
Yeah, he needs to not try and drift that. Especially if he's an amateur. He's going to make one less good example of an e36 m3 in this world.
Hey me n my bf love your channel, we watched some of your videos and we recognized some of the landscape. We think you film near where we live! My bf has an E36 too and it would be neat if yall could meet up. Hit me back if you're interested!
Its just for comfort, bmw doesn't give a fuck what you do, its literally just to make clutch engagement smoother, therefore taking off and shifts more comfortable
Everyone who's has a 540i/6 knows this mod, not sure why it's "so unknown" in the e36 community
oh this is the reason the car keep accelerating for a second after i press the clutch
I think i got this on my car aswell. Not bmw tho
Interesting that this is removed when Clutch Masters actually sells a "dampener" to install on vehicles
Dragracers use it or some kind of valve alike. It's not always that if a part is on a car it has to be there in order to make the car or clutch in this case function properly.
The real ones know you leave this valve in your e36 to save the axles. My bone stock 250k mi 328is tandems with 265s on the back wheels lol
You can just remove it and screw the line back in you wasted ur money
True! The UUC CDV still has a slight restriction it is just a lot less than stock. I personally didn't want it wide open.
Its even better, if you just remove the thing and fix it back together
@@TreatsOnTheStreets I just replaced the whole line with a ss clutch line for 60$ and now I dont have to worry about a line breaking or overheating and bursting.
@@TreatsOnTheStreets how does a CDV cause premature wear on the clutch? Yes it is causing the clutch to slip a bit but it's also reducing the force/energy of an immediate engagement. Just curious I am not an expert.
@@scottmason1012 because it slips the clutch, sometimes excessively. It is especially bad when going from a stop aggressively or shifting while accelerating aggressively. It essentially rides the clutch for a small amount of time and the extra slippage wears down the clutch faster. If you do not drive your car hard it usually is not that big of a deal. If you drive like I do the slip is very noticeable.
All that power and still clutch kicking? a quick flick and i bet that would break traction easily? A great mod though, I did it to my E36 👍
Tnx for the info, I will definitely follow what you hav done to your M3.
Chasing for unrestricted control, sir this is what driving's about, subscribed.
Welcome to the channel man!
Duuuude! I got that retro wave e36 tee few weeks ago too! 🤘🏻😊
Where did u get it?
If I am not mistaken that CDV is not on Euro Spec models....I have checked the parts manual and its not on any S50 engine code models.
My e46 m3 doesn't have one of these and I know it because it didn't have a clutch pedal from the factory but it does now ;)
Literally no one cares
@@screekid hey Jake ever heard of ligma
@@iancook2921 sweet, made up words for absolute neeks
btw I live in utah and I drive an e36 m3 that I am almost done with a LS1 swap on it. I wouldn't mind riding with you at an event next season.
Where in Utah?
DON'T SLEEP!! I would say good luck but if you win it, I can't.
Denofa leaves the cdv in so not to shock the drivetrain.
The dual mass flywheel still dampens it somewhat.
Yup, without it those driveline forces get transferred to more expensive parts. Just ask AdamLZ
There's not much to worry about at near to stock power levels as long as you're not using a highly aggressive clutch. Mine is weak so I got nothing to worry about lol
Adam lz has way more power and torque where the CDV won't really hinder things too much. It makes sense to keep if you have much stronger power than stock.
I wonder if mine even has this. I've never noticed any issues with letting out the clutch. Feels identical to the e39 M5 I had which doesn't have a cdv. My M3 will definitely grab second without thinking twice about doing a rolling burnout.
Now I don’t drive a manual or know how to drive one but it seems as if the valve slows the disengaging of the clutch for daily drivers and new manual owners as to not stall
It's a BMW...is a luxury mod by factory for a super smooth clutch/over car feel.
Also that peice you bought isn’t necessary u can just remove the cdv and reconnect lines in same place
Why did I just lean about this today.
Nice locations you film at! :)
what was the e36 dash shirt in the first few seconds? its sooooo gooood
She passed the listening test.
This is crazy...never new this.
Already got an ls in mine. We good.
We need to do this on our E46 for sure.
Where do I get said valve? 😅mine needs this lol, followed on Instagram and Facebook✌️
If you don’t have that part you can make the little hole bigger with a drill
If you had EU m3 version you didn't need any clutch kicks to get start wheel spin 2nd 3th gears tho....
Is it possible to just drill the hole out on the stock one and send it?
Actually, a lot of drifters use a similar device to reduce shock on the transmission when clutch kicking! That thing is of course adjustable 👍🏼
exactly. my train of thought is if you're kicking the clutch constantly, would you not want to leave that part in? its going to prolong your clutch and driveline
It won't prolong your clutch it will make it wear faster. Slip and heat is what wears clutches. With the valve in, every time you kick the clutch it will slip on engagement. This valve is only useful in high power cars with weaker drivelines where they can not handle the shock of crisp engagement. Clutches will wear much less without one of these if you are hard on the car. For someone using the car as a daily driver it probably won't make much difference besides feel.
They put that in there to make the clutch engage smoother so customers don't complain. ...worked for 3 stealerships BMW as a Master certified tech for 18 years. It's not because "they don't want you to drift". They couldn't care less what "you" do. Most of the customer base for BMW is RICH people who just "want a BMW". Most of them are not into "spirited driving" and would absolutely complain about the clutch engaging too hard if they had put some thing decent in it. ALL M cars suffer from terribly weak clutches. Take any of them out bone stock and floor it and shift hard, it'll slip! ...and I hated it!
I want that E36 T-shirt with the interior/dash/steering wheel in the colours, where can I get one kthx
When you find it ...tell me aswell
Didnt know thet came factory with that...Hell us Honda, Toyota drag racing guys buy a valve to relase the clurch like that. Best way to launch fwd. But no not good for drifting, or road racing
I will always love a BMW e30 and e36
Jup, was tje first and best mod on my e60
Removed the CDV from my 01 325xi years ago... for some reason I still can't drift, lol. ;)
edit: I agree... having driven manual a long time removing it does make it feel more intuitive and natural again.
LOL OMG! I can't believe you waited so long to do that!
You absolutely did NOT need any parts. You don't have to replace it, the fittings are identical on both sides of the valve so you can (should) just remove it and put it in your personal BMW parts museum.
First thing I have done to every BMW I have bought is to replace the soft clutch line with stainless braided line, and pull out the "granny shift" valve.
I have 5 of them in the top drawer of my toolbox LOL. (but I only still have 2 vehicles, E83 and E36 M3... both of which have the stainless clutch line and no valve)
I will repeat... You do NOT have to replace the valve with anything. Just take it out and connect the flex line to the hardline. It screws directly together. (bonus points if you replace the spongy rubber line with braided stainless though)
Great insight and nice collection!
but ppl like making it look more legit
6:36 yea from what I've seen the cdv is vouched by drift guys running 500+ whp so that they dont rip apart their drivetrain. if you're near stock tho most likely you'd prefer it out
Exactly! I wish I could say I had 500hp and not have to take that out 😂. Maybe in 2021....
The only guy I've ever heard saying that is Chelsea Denofa, and while he's very knowledgeable, there's plenty of other people running way more power than he does with no cdv. I'm sure you watch Adam LZ and that's where you got it from but tbh I think he runs no Guibo and that's way more likely to be the reason why he broke a gearbox.
Edit: He had a guibo before because he was on a stock drive shaft but I'm quite confident he swapped to a single piece driveshaft with no guibo when he blew the 1j that was in it
@@imnota nah I've seen it being used in other cars not just e36s. high power drift/drag cars with expensive trans/diff setups that they'd prefer to not blow up. definitely a more niche use case but that doesnt make em useless.
@@paperboy725 It's used in drag racing, and the only use is for people that don't wanna slip the clutch by themselves, but Denofa is the only guy I've ever seen using a cdv for street and drift cars.
@@imnota okay cool... Whether or not the ones I've seen were "copying" denofa, I've seen instances of other people claiming to use it/discuss using it. not sure why you seem so eager to make using a cdv a thing by denofa
You need to learn more about cars. Its crazy that you're just learning about this now. You want to drift, there are things you need to know.
1.Weld your diff
2.Boost your car ASAP because those cars are DOG SHIT SLOW.
3.Get a bucket seat so you don't slide around on the leather.
4. Get a performance clutch to engage the way you need to in order to drift.
5.Get a short shifter for smoother shifting
PS. I was commenting on this before I heard you comment on getting new seats. But my point proven
just to note not all e36s have this valve. Only restyling OBDII models. Pre-rest and all OBDI don't have it. It's a simple job removing it and yes it is cheap and good 'mod'.
Gavin, you'd be stoked to have sintered clutch in your vehicle then.... my wheels spin even when starting out from the idle. :D Kinda hard to live with as a daily but it's awesome for actual driving. Btw now you can do proper clutch kick... you don't need handbrake at all. Let the car roll at 4k rpm in the first gear, then clutch out to second, rev to 4.5 - 5k and let the clutch out. That's for slow 'drifting' donuts etc. you can always go faster and clutch kick in 2nd gear but i wouldn't recommend that to you yet, i'd be so sorryto see this car broken... Also re that drift event... go but not with this car. It's like a diamond, perfect condition really, your heart would break evn to scratch some paint, let alone putting a bumper or a wheel into the barricade.
Nice videos dude! Subscribed!
Welcome to the channel!
If youre gonna pursue drifting to actually try and become much better, i would advise buying a cheaper 328 thats already rusty/beat up bc in drifting one way or another youre going to crash and ik youre going to beat yourself up if you mess up with the m3, i learned that the hard way too haha
I wouldn't do a ton of drifting with this. A little a probably fine but I don't plan on making this a dedicated drift car.
Where on my Touring do I find that sucker?
why not just drill a bigger hole trough the old delay valve?
You could do that
Why would u put something instead of cdv if you can just cionnect both together and not put anything in the middle? Because threads match lol no need to buy anything. Had the same valve on my e46ci , took it out, never looked back.
Amazing video, this guy needs moser credit
I used to have one 99 e36 m3 . The greatest car before I got the e39M5
Is there the same thing in the e46? Damn I hope not😭
My 1995 m3 doesn’t even come with traction control 😂 so nothing to remove
Question could you take the stock one and just drill it out you might as well try since you already have a better one
You dont need to buy that valve. Just removed valve and reconnect. First thine I did 15 years ago.
Please a link to buy the shirt you wear
Yes! That E36 shirt with the neon colours is dope AF, need it in my life!
The outro ❤❤🤩
I just took mine it everything still bolted together 😂
Didnt buy anything
Dropped that CDV like a bad habit almost right away. :-)
Is that only OBD1?
