Dear Charles, we NEED another series with Paul like the Scirocco one. Right. Now.

You seen like such a great guy, i can watch this forever. Bravo ! Greetings from The Netherlands

Great job. I repair haldex pumps, I'm not a mechanic but I occasionally worked in a workshop, very detailed work, all credit to that.

I was actually able to revive a dead pump by tearing it down and cleaning all the debris out. There was about 2/3rds as much debris inside the pump as caught on the screen. Going forward I will be disassembling the pump every time I do a haldex service. The internals are pretty simple, not many components and it only takes an extra 10 minutes. Just have to remove that last torx bolt on the face that the screen sits on. Be careful because there are some springs inside.

As a non VDUB driver I use this to perform the maintenance on my SAAB with a Haldex. Thanks Charles!

[antilogism]

It's been 3 years since I last changed my fluid so I'm here for a refresher. Thanks!
My manual on my 2015 A3 says 32 Nm on the drain and that both fill and drain plugs should be replaced.

Pretty scary the dealer has no seals! Reminds me of Ford, when I went to the dealer for the then exotic transmission fluid for a scheduled change, the lady at the counter said they have none, have never ordered it nor had it in stock.

Glad you covered the pump motor reset in VCDS! That was the magic sauce for my S3 Haldex service. Turns out my pump hadn't been primed after the previous Haldex service (before I bought the car) so I was running 2WD for a few years without realizing it.

Nice and clear video on Haldex Maintenance Charles!

The Pump basic settings is not to prime the pump but to calibrate the pump.
Without correct calibration the generated pressure scheme is not correct and you will have wrong pressures.
Always do the calibration when cleaning or replacing the pump.

Great Video.

I did my Haldex and DSG at the same time. Makes it easy to remember. My MK7R is also tuned and driven aggressively.

Hello!
I understand that in addition to oil and pump maintenance, this system has a cartridge-type filter and I don't see them changing it.
Because nobody changes this filter, I only saw 1 video that did it but did not do the maintenance of the pump.

Thanks for the video!

Man... 4K/60 videos like yours ... pure plesure to watch !

Great video Charles! The Haldex is one of the most neglected components in an AWD car, right up there with the differential and brake fluid.

I had the Haldex go bad in my Ford Five Hundred. Yes, you read that right - a Ford! Ford had partnered with Volvo in the late 90s, and the Ford Five Hundred/Freestyle both used the Swedish Haldex as the AWD coupler. I believe Ford still uses the Haldex all through Taurus and Explorer production too.

FYI - The reason the AWD failed on my car is the screen was completely blocked with particles from the wet clutch. When this happens the pump will eventually overload and short out, taking the differential control module with it. That's what happened to me. Luckily there were enough of these Fords in the wreckers that I got a replacement DCM, but I did buy a new pump. Ford says this is a 'sealed for life' system, which is a total crock of crap. It should absolutely be a service performed every 30K or 3 years, which ever comes first.

BTW - The Haldex service on that VW was a breeze compared to my Ford. On my car you have to REMOVE the driveshaft to pull out the pump, as the CV joint flange on the drive shaft blocks the pump, and there's no room to temporarily move the drive shaft up out of the way. Also, there's no drain plug! You're supposed to vacuum suck the fluid out the fill hole. I scoured the Ford forums, and although it was not recommended, many people drilled and tapped the case for drainage. That's what I did - no regrets!

As for the AWD fluid, Ford didn't have it in stock at my local dealer, so I went to the Volvo dealer instead. The Volvo fluid was half the price Ford wanted FOR. THE. SAME. DANG. FLUID. GRRR!!!

Regardless, the AWD 'wrench' light turned off after the service, and the AWD has been flawless since. So learn from me: Maintain your Haldex!

Thanks for the video Charles - cheers from Frosty Canada!

[Andrew-zvfm]

Not sure how I feel about the new style of filming with the camera moving around. But great that you are trying to something new.

[Wolfpack]

Wow your pump looks clean.
I have serviced a bunch of these and never seen one clean like this

[Kamukix]

Thanks for this, I always do my own work BUT decided I'd drop it off at the dealership to have the Haldex and both F&R diff fluids changed just to have a paper trail if I sell the car in a year or two.

They did the F&R diff and I said I didn't see mention of the Haldex service and they said there's nothing on the recommended service schedule because they're the same thing lol.

I didn't bother to press them and I'll just change it next weekend myself lol.

[FTG]

Dude, your delivery and editing is top notch. Amazing job!

[RandomYoutuber]

Great video. This applies to all newer 2016+ SPA & CMA volvos with AWD.

[quattrolheads]

Seeing the easy of service on the Golf R makes me slightly regret getting my B8 S4, regardless great detail in your videos and your car is still looking great! Good luck with the S4 you got btw!
