- Lesson in doing your own work:
I've taken my car to the VW dealership / service center to have any scheduled maintenance performed as to not be held liable for my own work "voiding" any warranties. Now at 59,600 miles, there was barely any warranty to void so I decided to work on the car myself and upon doing that noticed the dealership never did the 30K mile Haldex Fluid service. I brought this up to them but had no recourse, they didn't bring it up and I simply went off of their recommendations.
As it's ultimately my responsibility to make sure proper service gets done on my vehicle, I decided to do it myself and film the process.
I believe this service procedure is also applicable to Audi, Seat, Skoda, and Volkswagen group products that utilize Haldex systems
Great video, shows all the steps and even the prime section at the end that most people do not mentioned.
Thanks
Thank you for the comment!! I appreciated it! Glad you found the video helpful.
Good tutorial. Thanks
Thanks for watching and leaving a comment! It's nice to know i was able to help somehow.
Nice work. cleaning the haldex screen is not even part of the vw service procedure, yet there's so much gunk in there.
This is beyond a late response but thanks for the comment!! Much appreciated. I was surprised by the gunk too, I’m even more surprised that some other cars I’ve seen have had even more buildup! Amazing unit though.
Even though you ‘have no recourse’, I hope you complained to VW corporate about the dealer not following scheduled maintenance. Two reasons: any potential future warranty-related issues, and to let corporate know which dealers deserve a reward and which deserve less love / future allocations. I’m not a fan of punishment but the dealer needs to do you better than that if you’re being diligent and using them for regular service.
I did and their advice was to take it up with the dealership in my area (which has not been responsive or ever gets back to me). Currently at 68,600 miles and all is well for the most part. Thank you for the comment!
Thanks!
Absolutely my pleasure. I have 2 more to edit and upload regarding DSG service and Engine oil change. I appreciate the view and comment.
Thanks for this video, it helped me a lot.
Just one thing, I thought there is also an additional filter, which looks like a small cylinder. Is there a reason why you did not replace this filter too, because it seems there have be a lot of contamination within the circuit.
Thanks for your answer in advance.
Phenomenal question :)!! So This was pointed out by another viewer (@graeme wilton) earlier (so keen eye to both of you). Honest answer is i did not have prior knowledge of that filter. Upon digging into it, it's not even listed as a serviceable part by VW. (I believe Audi, Skoda and maybe Volvo utilize this part as well). So I'll be doing that part of the service in 20K miles (which at this rate will be within 18 months). @sbcncsu did a fantastic video that includes that service

Thanks for watching and commenting! I really appreciate the engagement!
@@driven15 No problem at all :-), I believe if I would combine your video with the video of @sbcncsu, probably the best possible maintenance for the Haldex :-).
However, I have read, that it might be also about the question of the generation of the Haldex clutch. There are some, which do not have this filter. But again, thanks for all the information, because I plan a Haldex-Workshop on our Tiguan during the next months.
Cheers
@@gustirolli441 Cheers!! Good luck with the service. Again, i appreciate the audience and engagement! Makes putting this videos together that much sweeter!
If you allow me one more question. It seems that you are working very carefully and well considerate. I plan to change the fluids for the differential transmissions (front and rear end) the drain plugs as well as the fill plugs are the same as the fill plug for the Haldex (N-902-818-02). For the Haldex the Torque is 15 Nm. Do you know what Torque I have to use for the differential transmission. VW Switzerland nor google or Forums were able to provide me with an answer and my goal is to make it right.
Thanks for your support and my apologise for bothering you :-)
@@gustirolli441 allowed as many questions as you would like sir :)
SO the Torque setting will be roughly the same: 15Nm for the smaller diameter bolt up to 20-25Nm for larger diameter drain plugs. The main point behind torque settings on fill and drain bolts is more so to "deform" the new crush-washer to the mating surfaces (surface of "container / vessel" and bolt) than for bolt retention (making sure it doesn't fall out). So Torquing to 15Nm or 25Nm will deform the crush washer enough to ensure a proper seal.
I will give credit to the folks at Deutsche Auto Parts (shopdap.com) for helping with those answers for me too when i had those questions :)
When you said cycle the key, do you mean just to turn the key but not to ignition, then turn off, and repeat?
Good question! So if the car is push button start, just push the button with your foot OFF the brake. If it’s an inserted key, you cycle the key till all systems are powered (AC, Radio, Windows...etc) but the engine never gets power / turns over. You will hear a whine while the pump cycles.
@@driven15 Thanks! And how many times should I do this?
3-4 times should be fine honestly if you’re playing it safe. Eventually it’ll charge with enough fluid. Thanks for watching and commenting! I appreciate the views and engagement in the video :) good luck with the service
@@driven15 Thank YOU for making this video with all the details! Really helps with someone without vagcom.
Hello. Did you replace the filter altogether? Or just clean it? And had you lost rear wheel drive? Plus have you done any modifications to your car?
can you please answer me as I’ve lost real wheel drive and VW are telling me that I have to replace the whole rear diff for the cost of $7700 in Australia. Thank you
Although I'm not the guy replacing the oil in the video and not an expert on the subject. The problem you have can be due to a lot of different things. It could be the pump itself. It could be sensors. It could be the control unit etc.. It sounds a bit drastic with "the whole diff". You might want a second opinion at another shop. (I have the same Haldex system in my XC60 and reading a lot in a local Volvo forum. That and I have just ordered a T-Roc got me to this video as I'm interested in general)
Håkan Kristiansson ok. Thank you
Håkan Kristiansson it was a simple software update. VW couldn’t work it out apparently!
@@anto11b Happy to hear! Was that fixed at another shop then the one you first visited?
Hey Anthony, sorry for the late response:
I didn’t replace the filter all together, just cleaned it from the inside out with brake clean then allowed to air dry. It was not damaged or compromised so I didn’t seam it necessary.
I had not lost rear wheel drive and thanks priming the pump during the procedure, I didn’t when I started driving again. Winter in Wisconsin now has given extra changes to break loose and still performing top notch.
No modifications to the car. Although I’m a fan of performance as an engineer that works on Process Reliability and own Autonomous Maintenance for a large consumer products company I’m a DEEP believer in leave letting things be as the original designers wanted them :). I fully understand these cats can handle a lot, I loved it the way i bought it haha.
As for your issue with VW. Not sure the causes for loss of power to the rear. I can definitely try and help trouble shoot, I’ve kept good contact with folks at Deutche Autoparts here in the US. Can always put you in touch with some folks there as well.
I find it more "idiotic" to presume that changing your own oil and doing your own maintenance in any way jeopardizes your warranty, assuming you're in the U. S. I actually just turned 10k miles on my 2019 Golf R and will be doing my second oil change, as well as my first Haldex service this weekend. All parts and fluids ordered from DAP.
Ataratic Resonance ASMR Thanks for the comment. I see the light in what you’re saying but obviously made my own decisions on when to service my cars. Although I have full confidence in my thoroughness when doing services on my own cars, these are cars and things do go wrong with them. Having said that I don’t have full confidence in a dealership “trusting” my thoroughness. I’ve seen it require more than a good paper trail and thorough documentation for dealerships to uphold doing warranty work. They can blame the grade of fluid you used, the OEM-ness of a part, the WAY you did the service and hide behind you introducing external factors to justify why what went wrong was because of how the service was done vs a malfunctioning of the warranties components. I agree with your what you’re saying but factoring in the local dealerships / service shops in my area, I maintain my logic of why I didn’t service the car myself earlier.
Ataratic Resonance ASMR having said all that, I honestly do agree with you and will be doing my own services (with solid documentation) on all my cars new and old. I trust myself more than the dealerships. Good luck with the services and thanks for the comment man. I hope the video was useful. And enjoy the R dude. I absolutely can’t stop driving mine. 70K miles and 3.5 yrs. We need an extra fridge at home because I keep “needing to make a quick run to the market for milk” haha
@@driven15 Same. Love driving it. Had a 2018 GTI Autobahn for about 8 months just prior and it was also fun, but the R is amazing. Such a well engineered machine. I only wish I lived somewhere where inclement weather were more common. 🤔😊
Ataratic Resonance ASMR dude no joke, that’s partly why I haven’t wanted to move out of Wisconsin! LOTS of roundabouts here and in the winter it’s a state wide skid pad haha!
@@driven15 and you all have access to fresh cheese curds!!!
Did you use the same haldex fluid in the diff and haldex?
Thanks for the comment / question. I’m not 100% certain but I’m fairly confident they are both a single reservoir unit using the same fluid, yes. I only used one fluid (fluid as mentioned in the video). I hope this answer helps.
Did you end up doing the service? How did it go?
Differential has two different reservoirs for two different kinds of fluids the front part of the differential is the hell decks which is a friction oil and the rear part of the differential is gear oil obviously for the differential. Found out the hardway. Be careful!
Thank you so much for shedding light on the question! That’s why I love this community (collective knowledge). I didn’t end up draining the differential itself but did the Haldex fluid service. So I made the assumption, thank you for the correction there.
how much fluid do you use?
Ended up using slightly less than 5 liters (just under 5 of the containers the fluid came in).
could you post the parts numbers please
Absolutely:
Haldex reservoir bolts
Fill Bolt (5mm hex): VW 02D525729
Drain Bolt (8mm hex): N91082701
Fluid: G 060 175 A2
Pump & Filter assembly parts:
Bolts (T30 Torx) and the O-Rings come as a kit: VW 0CQ598305
The syringe I got from ShopDAP.

Thanks for watching and commenting, I appreciate it! Good luck with the service.
@@driven15 awesome thank you
Piotr Kozlowski hell yeah, happy to help! Cheers and thanks again for watching!
You know there is another filter just above the pump that needs replacing.
I was actually not aware!! I'll take a look into that and maybe tackle it during the next Haldex Service I'll be doing. Thank you for pointing that out :)
How did you find out about it? Bit bummed I missed that.
@@driven15
you can dislodge it by loosening the 2 screws then cycle the pump to build pressure to pop it out.
@@MrLooperg Looked at the link you shared. Thank you SO very much. After reading the comment I did some digging around and found the filter. However what drove me nuts was I couldn't find it in VW's exploded diagrams with parts listed. Thanks again, much appreciated. I'll make plans to address this filter in the next service and do my Homework between now and then on how to properly execute!
@@MrLooperg Sorry for commenting so much now! So with some further digging around and reading, I saw in the link's description and on a page I found that VW doesn't have this listed and does not "acknowledge" the Filter are a serviceable part. Interesting! Good find!!!
@@driven15 Hello. You golf r has a Gen 5 haldex. This means that you don't have the extra filter that is replaceable as the haldex gen 4 has. You only have the mesh grill inside the pump that you cleaned correctly. Thats why you can't find the extra replaceable filter in drawings. You dont have one.
