Editor: "should we use stock pictures of cars?"

Nice
I know Haldex gets a lot of flak for not being as track performance oriented as some others, but boy is it excellent all-around system. Coming from a RWD + snow tires setup in the past, I now drive a MK7 Golf R + snow tires. Sunday we had 4-5" of snow here in MD and it still blows my mind how effective it is in the snow. I went up an unplowed steep hill with absolute ease, not even a hint of slippage, no flashing lights, nothing. As if I was driving on dry pavement. I've floored this car before in the rain and it hooks up no problem with just a hint of initial wheel spin, and that's with a JB4. And when you don't need it, you're enjoying all the gas millage efficiency of a FWD vehicle. No there is no drift mode, and it doesn't transfer enough power to make it feel RWDish. It's a fair compromise for my daily duty usage.
Its a good system, but just doesn't drive as well as the Torsen systems when you really flog it. Maybe if had gears ahead of it to provide more rear bias. (I've got both systems)
Because his split numbers are incorrect. Haldex isnt the same in all vehicles. Just because your vehicle has haldex 5 doesnt mean it has the same split as every vehicle with haldex 5
yeah pretty much awd for sissies.
99Lezard99 Just like Subaru. LBGT community favorite car
@@v60polestar88 haldex awd=handles like fwd. thats it
Thanks for mentioning the SAAB part of it :) I bet many SAAB enthusiast would love to know more about the actual generation used in SAAB vehicles, since there's not as much info on it as we'd like for sure.
Saab NG uses Generation 4 branded XWD en.wikipedia.org/wiki/Saab_XWD
The Haldex4 used in my XTS Vsport clawed like a scared cat. Turn off the TC a d stability a d it was power on slides. It also handled almost 600 lb-ft pr torque with a ecu tune.
Very informative video...but it made me miss my 2004 DBP R32!!! Nice respect at the end of the video! ❤️
I bought a clapped out 1G TT 225 and the haldex did not function. The wheelspin was epic! Decided to service and checkout the unit. There was NO OIL in it and it had the original metal filter. I replaced the filter and put new oil in. Amazingly enough it worked! The system was smart enough to shut itself down to save the pump! I could do a full on dig on gravel and it would just go. Amazing system!
Yes, just like most computers, when it overheats it shuts off to save itself.
Thank you for this and other videos Deutsche Auto Parts produced. I appreciate the time it took to do the research, draft a narrative that explain generational nuances in simple terms and the supporting graphics. I also like seeing your 2004 R32 and appreciate what it takes to keep this 15 year old car in top notch condition. I'm the original owner of a 2004 GTI VR6 and like to keep mine looking as good as yours and operating reliably well. Up to this point, I replaced worn parts with mostly OEM parts or aftermarket parts that perform like OEM but have better reliability... no high performance parts. Soon I'll give you guys a call to discuss some in-depth routine maintenance that I need to consider. I look forward to getting your expert advice.
That blue golf in the background is bloody delish.
Interesting stuff, thanks ! I always thought gen 5 could send up to 100% to the rear when needed , learn something new every day
I think the only full-time AWD system that can get even close to 100% to the rear is the ATTESA-ETS as it's a rear biased system. Most other AWD systems are front drive based as far as I can recollect. IIRC, Audi's proper quattro (not their Haldex systems, but their Torsen set-up) is still maxed out at a torque split of 30/70 FR bias, but with the advantage of actual differential torque vectoring (not using ABS to achieve a similar result). Certain Audi's have the Haldex while other Audi's have the Torsen layout. All of them will say 'Quattro', which I think is a bit misleading.
Really, Subaru's Symmetrical, Audi's Torsen (not their Haldex), Acura's SH-AWD, and Mitsubishi's S-AWC are the most...'versatile' AWD systems. The others are typically variations of Haldex with torque vectoring across planar axles via brakes.
There is a tweak you can make in VCDS on the golf 7 R to increase the drive to the rear.
1. AWD
2. Adaptation
3. Wiring logic
Standard setting is "Low Noise." There are the options for "Normal" and "increased traction."
In increased traction mode to me the car feels much more planted and really shoves you around the corners.
waste fuel.
Cyberdyne Systems yes I expected so as well but I’ve not noticed any substantial increase in consumption.
@@TH-camSupportTeams Still more efficient than a center differential
Thank you for all your hard and brilliant work Sigge.
The tribute to SIGGE was nice and touching.
Thanks for a good video. Recognizes me with patches on the chest. :-) Nice R32, I'm driving mk4 (VR6-T) 24v 4mo in Tief Blau (LB5R).// BW (haldex) employee.
I like the new style. Great video.
Haldex AWD is the AWD system that always mistaken as full time permanant AWD system because even if the clultch pack is unlink to rear axle, the rear axle still has torque between 5% and 10%.
Came for information on my gen 3 Haldex.
It was basically just glossed over.
Me too...How can you call this a history if 20% of it is missing? Can you please add something on the Gen 3.
So.When the Bugatti differential breaks, just go to junkyard and buy used one from Golf.
"bugatti" just another overpriced ponzi Volkswagen. Nothing special.
Only someone with a $1500 car would say some bullshit like that.
@@TH-camSupportTeams I take it you drive a spaceship then?
Although they're both made in the V.A.G. concern I sincerely doubt a standard differential from a Golf will take 1200 Hp from the Bugatti.
That TT looks clean 👀
I want your MkIV R32, they're so hard to find in good condition with no mods.. Very nice
Recently serviced my 2014 Tiguan based on PQ46 platform which is gen 5 haldex, which got rid of the filter.
Did you at least pull out the pump and clean the screen on its intake? I've seen some pretty nasty photos of those, and others that looked 100% clean -- that may depend on how the car has been driven.
Gen 1 also found it lots of other VW's that were not available in the US market, or UK market for that matter.
Notably mkiv Golf TDI's and the mkiv V6 4Motion, although the latter was sold in the UK...
and Europe's seat leon cupra 4
Great video!!! Keep up the good work! Big fan of the channel ;)
torsen 4 lyfe :) Great vid and thanks!
That r32 looks pristine
Very good video. I now know my VW has a gen 4 Haldex system.
Could we get a updated video of Gen 6 haldex?
Incorrect on the split on haldex 5. Haldex split is determined by the software programming by the manufacturer. My V60 Polestar is 70/30 split in normal condition and 30/70 with sports mode on and esc off.Unless the manufacturer gives you the split numbers your just assuming
On the gen 1 TT. The metal casing has “haldex” embossed on the casing
Much better than the 4 matic Mercedes system. My BMW X drive though was great in the snow.
I love this channel.
GM uses a similar system in their trucks but the clutch system is in the transfer case not the diff. When in "auto 4x4" it engages and disengages the clutch pack as it sees slip.
Thank you for this video it's helped me understand it a great deal more than I did and I found out I got the best system so far as I got a 2019 Golf R Mark 7.5
In addition to my great APR KO4 GTI MkV!😛
I have a gen 1 Audi S3 (210HP version when factory stock), which I’m guessing comes with a gen 1 Haldex. It’s currently modded to 350HP. I’ve been searching for docs for a while now on how to convert it to RWD for drifting, but haven’t found anything. I was toying with the idea of removing the front axles and then trying to electrically trick the rear clutch closed. Would that result in 100% torque transfer in the rear you think? Any pointers would be greatly appreciated.
So to get a 50/50 permanent split just remove the haldex rear diff assembly and then control power distribution with clutch packs?
Excellent info. Thanks!
An Audi service foreman at the dealership where I purchased my 2018 S3 said that when the Quattro mode is set to Dynamic, that there's always some power going to the rear wheels.
Is this true, or is it still 0% unless there's demand?
Thanks.
Excellent video. Thank you for the great content. I have seen you doing videos about the haldex system and I would like to know if you can make a video on how to troubleshoot this systems. One of my vehicles is a mk1 tt Quattro and I feel that the rear is not engaging as it should be (drove other haldex vehicles before). Thank you
Since a gen II and Gen IV are found in Audi 8P and TT, is there a vin # when they made the change?
So if the gen 5 haldex which is in the RS3 is predominantly 100 to the front but can send 50 to the front and 50 to the rear how is it that the RS3 can send 100 to the rear?
That comes from lack of understanding between static and dynamic driving behaviour. Static is 50/50, but car is a dynamic thing - there is changing coefficient of friction, there is transfer of weight etc.. Then almost 100% of torque may go to the rear.
2:35 AND WHERE IS SEAT LEON? IN CUPRAS WAS THIS HALDEX TOO!
Gen 4 gave me Gen 2 Deja Vu.
Great video.
I had a 2010 tiguan and now have a 2019 tiguan and I've felt front wheel slip, on dry road, in the 2019 that I never felt in the 2010. Haven't put the gen 5 to any real test yet but hopefully it does as good as the old one.
You may want to make sure your haldex is actually working. The pump failed on my 2016 S3 and basically turned it into a GTI. I started noticing that even with partial throttle it would spin the front wheels constantly on dry pavement which should not happen, even with 350+ ft/lb torque. I proved it by parking the front wheels on an ice patch and the rears on dry pavement. The car would not move at all, just spin the fronts. After the fix it is a rocket off the line. The gen 5 has no filter so it gets gunked up. My mechanic said he has seen a bunch of them fail at low mileages (30-50k).
Haldex Gen. 4 has also an oil filter. But in Gen. 5 they throw them out. And in different forum you can read a lot of fault clutches and pumps of the Gen.5
I think that was the bigest mistake they ever made.
Who cares? They're all shit.
It's also used in the Mk7 Golf SportWagen 4Motion.
Really cool video.
What I still don't completely seem to understand is if between the 90-10% and 50-50% torque transfer ranges there is a slip between the friction clutches in the Haldex differential or if it is achieved by fluid friction (ie: fluid coupling), since there isn't any type of "gearbox" to select how much torque is transferred to the front and rear axle.

This was awesome
MK4 R32 ❤️
Loving these videos.
Could you comment on whether the the Gen 3 Haldex unit (like in a mazdaspeed6) is a reactive or proactive model? From driving the car, it feels like there's times where the car just keeps the clutch packs engaged under spirited driving regardless of throttle input. Not confirmed but I've read that it is more similar to the Gen 4 unit (than the Gen 2).
Thanks for sharing
Hi there, with non permanent 4wd does the vehicle sense slippage on descelleration/ engine brsking in snow? I remember climbing well on a snowy road with a renault kangoo 4x4 but on the descent the rear wanted to overtake and 4x4 didnt feel engaged
Another great video guys! So I just picked up an 05 Passat 1.8T 4motion, is that considered a Haldex or does it have the Torsen From Audi?
torsen
B5 and B5.5 Passats had torsen awd because of a longitudinal engine placement.
Very informative and well explained video, thank you. What did the Audi A6s and A8s use during those years? They marketed them as Quattro AWD but you didn't mention them, were they on a different system?
Anything bigger than an A3 has/had torsen
Damn that R32 looks good
Hi I have a Mark 1 TT Quattro
I want to do a complete drivetrain swap and use the Helix on a Mark 4 Golf.
Will this be a straight forward Bolt on or is there a kit that I have to purchase
I think the way this should be summarized is, on VAG vehicles, it is referred to as a HALDEX, but is produced by BW. There is another example, mot very well know, on GM vehicles, dual wheel pick=up trucks, are called in sales brochures,. "dooley", after the person that patented the design, and when you look at other dual wheel p/u truck manufacturers it is spelled Dually.
so does my 2002 audi tt quattro uses a gen1 or 2 haldex? because the gen 2 haldex wasn’t released until 2001.
Great info!
Are you shure on passat b6 is gen4??? The parts inside the b6 are the same as golf5.
My haldex gen1 not work. Excludes my last drive. Replaced oil and filter, but she same is happening. I pulled the haldex, but i could not pull the valve out of it! Which is his purpuse ?
sooo gen2 or gen4 is used in Audi S3 8P 2007 and 2008 year models?
Can you make the video of Manga Powertrain's history?
Great information brother. Love from India.
So what was used in 8L and 8P S3s and the rs3?
Why you didnt mention other cars grom vag Skoda and Seat which use haldex ?
Love the Q3 with the boot, LOL
Is there anything that can be upgraded with the first gen system? We have an Octavia that uses it
You should do a video comparing Quattro Ultra in the new A4 Allroad and Q5 to Gen 5 4Motion in the MK7 Alltrack and MQB Tiguan. They seem to be similar systems. FWD based.
So my question is... Is there any way to hack the actuator to get 50/50 power to the wheel at all times?
There is a plug to replace the shuttle valve to lock in 50 50 split all the time. I dont recommend it except for off road competition...
Nice One! But pre 08 B6 passat uses the gen2 too.
Ok. I have a question. I have a Golf MK4 2.8 VR6 204bhp . From the video i'm getting that i have a Gen 1 Haldex. So can i upgrade it with the performance module?
MagnumBulletMatriX if your MK4 2.8 VR6 is a European spec and equipped with “4motion” Haldex system.. yes you can. I believe the only current upgrades that are available are HPA’s touch motion and United Motorsports tune.
i have the UM haldex flash on gen 2, the response is so much better along with cornering
It’s upgradeable if you can find a module (search haldex blue).
@@taiwilson8966 If its possible,drop me a link please.
@@JettaRedIII Thanks. I'll look it up.
What generation of Haldex would be in a 2008 8P S3 6MT? Gen 2 or 4?
Can you do one with Torsen
Hi guys
Has anyone attempted to repair a broken G5 Haldex? Is it repairable?
I have broken my MK7 Haldex .
If there is a video about MK7 R Haldex rebuild would be great.
Thanks
Maybe theres a place that can refurb it but I'd expect it to be a pretty specialized and complex thing to rebuild, have you spoken to any transmission repair shops?
I understand you're asking if there is a video but finding out if it's possible to rebuild and to get the parts would be a good idea.
Hi
I bought a used diff and it ceased up after two weeks without any abuse. I'm taking them apart tomorrow and see what's damaged. Probably jammed bearing.
Thanks for the vid. What system does the 2018/2019 A4 and S4 use?
VW Golf 3 synchro? Which clutch it have?
i Have a Seat mk2 Cupra. Is it practical to retrofit a Haldex system i wonder?
DAP Team? So does this mean the TTRS and the RS3 can't send up to 100% to the rear? when zero traction is detected at the front?
They can technically send 100% to the rear if the front wheels are off the ground. Really it's just the 50:50 split with the front unable to do anything.
do you know ford transik mk 7 using which haldex gen ? thanks
Does the 2015 Tiguan use this AWD system?
Not only the mk4 r32 had the gen 1, also ordniary 4motions
What website should I use to figure out all I need to know about my 2008 Passat VR6 4Motion wagon?....when I purchased front brake pads from Fields VW here in Daytona Beach he just ask for my VIN# to get the right parts... what resource did he use?.....yes,I made the mistake of going to AutoZone for brake pads for this car, will not do it again.
Lenwood Cruze shop at fcp euro. Good guys and have lifetime warranty on all their products.
@@stevanpopovic7459 yep, that site is 💯% useful,THANKS!.... Seriously,I appreciate the help!
No problem brother 👍
euro Passat also gets haldex gen5 now
So much hate for such a great system. I have had several torsen and haldex cars over 15 years, and the difference is negligible in street driving, even in deep snow. I wonder if the haters have ever even compared the two.
not much info on Gen 3 here
So could you put a gen 5 haldex system in a mk6 gti? 🤔🤔🤔 Or would that making things super complicated and it's best to just put a gen 4?
Awesome video indeed. Now with that being said, does the new Audi allroad use this type of AWD??
allroad uses torsen
@@trek3792 Right, I know they have always used Torsen. What I meant was, the B9 allroad is now configured to be a somewhat front wheel biased and system. For better MPG figures.
How does the latest Haldex do on the rollers?
th-cam.com/video/baIcx1cfXZE/w-d-xo.html
I'm pretty sure the Arteon is Gen 5 Haldex -- I'll look under mine when it returns next week.
Does anyone know what version of haldex is in the MK7 (2017) Golf Sportwagen?
He mentions in the video. Gen 5, same system as Mk7 R.
So 100/0 set up for flat towing the vehicle ? Anyone knows?
Haldex, is King
What about the new Audi A4 allroad?
Skoda yeti 2015 4x4 2.0 CR ,generation???
Hello. who read Haldex 5 system documentation?Who fast 4 or 5?What you think?
PS very beautiful Golf R32 mk4 on video.
I'm having Audi S3 8p , how can I check it is haldex Gen 2 or Gen 4 ??
Jackie Chun its gen 2
Actually I had a 99 passat v6 TDI 4motion with haldex and 99 golf v6 had also haldex r32 came in 2002
is sub awd the same?
Let's talk about other forms of "Quattro" now... Not just Haldex.
...Does quattro offer other patented designs other than Haldex?
