Haldex Sealing Washer and Plug Set in OE Supplier

A four wheel drive part: the sealing washers, which are single use and which reusing gives a slow weep that empties a Haldex unit over a year.

We are an independent parts supplier. We are not Volkswagen, Audi, Seat or Skoda, and we are not appointed by any of them. Those are their trademarks and what we sell are parts that fit their cars. The useful thing about this group is that four badges share platforms and share parts, so the same component fits a Golf, an A3, a Leon and an Octavia and costs four different amounts at four different counters. We list it once, at one price, and tell you which platform it belongs to.

Specification and fitment

• Fits: Golf Mk5 Mk6 Mk7 Mk8, Passat B6 B7 B8, A3 8P 8V 8Y, A4 B8 B9, Leon 1P 5F KL, Octavia 1Z 5E NX, and the other group cars on the same platforms with four wheel drive, badged 4Motion, quattro, 4Drive or 4x4
• Platform: chosen above, and the Haldex generation matters more than the platform does. This part is shared across the group. The Volkswagen, the Audi, the Seat and the Skoda all take it, it is the same component in four different boxes, and the price here is the same whichever badge is on your car. Choose your badge above for your records, not because it changes anything.
• Engine: not engine dependent. This group changes specification mid production and does it on a platform basis rather than a model year basis, so two cars registered the same week can take different parts. Send us the VIN with the order and we check the part against the build data before anything is dispatched. It takes two minutes and it is the difference between a part that fits and a return.
• Production dates: 2003 to 2022 depending on platform and generation
• Quality: made by the firm that supplies the group, in that firm's own box rather than a dealer box. Same casting, same line, and on a group that shares parts across four brands this is where the saving actually is
• Part number: cross referenced to the group part number for your VIN and confirmed before dispatch. We do not print one number against a listing that covers several supersessions, because on this group the supersessions are the whole point
• The failure this addresses: Haldex four wheel drive is not permanent four wheel drive. It sends drive to the rear when the fronts start to slip, through a clutch pack operated by a pump. The oil and filter want changing every 20,000 miles and almost nobody does it, and when the pump then fails the car quietly becomes front wheel drive. Most owners find out in the first snow of the year, several years after it happened.
• Labour time: one and a half to three hours, and longer where the clutch pack comes out
• Coding: a basic setting or adaptation is required after fitting, which is a five minute job with a proper diagnostic system and is not possible with a generic code reader
• Also needed: the correct Haldex oil, the filter or screen for your generation, and new sealing washers which are single use
• Torque: the pump and filter housing bolts are torqued low. The unit is aluminium and does not forgive an impact driver
• Interval: every 20,000 miles on the oil, with the filter where there is one. This is the interval nobody keeps and it is why most Haldex pumps fail
• Weight: approximately 0.1 kilograms
• Warranty: two years or 24,000 miles, whichever comes first
• The silent failure: when the pump goes the car just becomes front wheel drive. Usually there is no warning light, it drives normally in the dry, and the owner finds out in the first snow, often years later
• Test rather than assume: a live data read tells you whether drive is reaching the rear axle. On a used four wheel drive car it is worth doing before you buy the car
• The right oil: Haldex fluid is a specific oil. A gear oil or an ATF will damage the clutch pack
• Generations: the earlier systems have a serviceable filter, the later ones a pump screen. We confirm which from the VIN

What arrives

• the part as described
• the filter or screen for your generation where applicable
• single use sealing washers
• the correct fluid where the kit includes it
• instructions with torque figures

Fitting

One and a half to three hours. Torque the housing bolts low, use new sealing washers, and afterwards test the four wheel drive function with a live data read rather than assuming it works because the part is new.

Which version to buy

Haldex four wheel drive is not permanent four wheel drive. It sends drive to the rear when the fronts start to slip, through a clutch pack operated by a pump. The oil and filter want changing every 20,000 miles and almost nobody does it, and when the pump then fails the car quietly becomes front wheel drive. Most owners find out in the first snow of the year, several years after it happened. So the question is what state yours is in. If the oil has been done every 20,000 miles, buy the service kit. If it has never been done on a 90,000 mile car, the pump has probably already failed and the service alone will not bring the drive back. We will read the live data for nothing and tell you which of those you have.
