If your VAG Group vehicle has four wheel drive it's likely the real wheels are driven through a Haldex coupling located alongside the differential, depending on your exact model. Whatever the model, it will require regular oil and filter changes; just like your engine does.

Haldex oil should be replaced every 20,000 miles and the filter replaced every 40,000 miles.

Unfortunately it was too late for this customer!

The Haldex Coupling is a very sophisticated piece of engineering and it needs to be looked after with regular oil changes.

The coupling is a submerged, multi-plate, wet clutch system that engages upon slip and transfers power to the rear final drive. The Haldex Coupling is a separate component to the rear final drive, but is directly attached to it. The system is computer controlled with very fine engineering tolerances. If the Haldex oil is dirty, it can damage other components and affect performance.

Dirty oil can overheat the coupling or cause the clutches to burn out. It can also burn out the Haldex Pump and will lead to loss of rear drive and eventual failure.

The Haldex pump pre-charges the oil inside the Haldex assembly to allow the coupling to engage faster. This part is prone to failure on higher mileage cars, or if regular maintenance in not performed. If your pump is faulty you may experience loss of engine power to the rear wheels due to the pump becoming contaminated with old fluid and no longer activating.

The Haldex 4WD system is currently used in the following vehicle models:

Audi A3 quattro
Audi S3
Audi Q3
Audi TT quattro
SEAT León 4
SEAT Altea Freetrack 4
SEAT Alhambra 4
Skoda Octavia 4x4
Skoda Superb 4x4
Skoda Yeti 4x4 (Haldex Fourth Gen)
Skoda Yeti Outdoor 4x4 (Haldex Fifth Gen)
VW Golf R
VW Bora 4motion
VW New Beetle RSi
VW Passat 4motion B6 Platform
VW CC 4motion
VW Sharan 4motion
VW Tiguan
VW Golf IV 4motion
VW Multivan 4motion
VW Caddy 4motion
VW Transporter 4motion

Hi,
I changed oil in diff and Haldex (4gen) on my Freelander 2 just yesterday.
Today I went for a longer trip and I’ve got a bad pulling/tuging/jerking behaviour when I drives about 70mph. It’s happening from time to time. Single pull, like slipping clutch or something or like something is pulling me to the back, but just for a single second, It’s hard to explain. When I drives slow it’s works normal.
When I was changing oils I removed the pump out and spray it with a bit of a brake cleaner, I took filter out but only clean it and I put it back because I had wrong filter wih me (3gen). New one should come tomorrow. I used recommended geniune Volvo oils.
Please help.
Many thanks.

I have VW Tiguan serviced from new at same VW main dealer. Last service Feb 2019. (104000) approx.
Returned car last week for water / roof problem and VW service asked about Haldex oil and filter.
If this requires oil and filter ay 20k & 40k would this have been included during service. This is first time I have heard about Haldex.
Please advise.
Thank you.

L.R seem to be blind to the haldex, they say it’s a sealed for life unit and dosnt require servicing,,,,,,,I can understand why they might say this if they have ever tried to service one on a post 2010 vehicle,It’s a wonderfull design,(not) the pump is so close to the drive flange that you have to drop the propshaft and remove the flange to get at it
