Haldex service for VW & Audi vehicles

Volkswagen and Audi vehicles are known for their quality, performance and innovative features. One of these features is the Haldex, an integral part of VW and Audi’s 4-wheel/all-wheel drive technology. It’s important to make sure your Haldex is serviced and here’s why.


The Haldex is a coupling system attached to the rear differential of a vehicle that allows rear drive to be brought in when needed, enabling all-wheel drive. This system is designed to improve traction, handling and stability to ensure a safer and more controlled driving experience, particularly for off-road driving. If your wheel starts to spin or understeer, Haldex will kick in to provide rear wheel drive. It is a remarkable feature that sets many Volkswagen and Audi vehicles apart in terms of performance and safety.


The Haldex system works by monitoring various factors, such as wheel speed, throttle input and steering angle. It uses this information to determine when and how much power should be sent to the rear wheels. The newer Haldex versions can even anticipate when they’ll be needed and to what extent, all thanks to the data they’re getting from the vehicle.


Servicing the Haldexi is essential to maintain its performance, safety and reliability. When four-wheel drive kicks in, the clutch engages causing friction. This friction gradually builds up small particles over time that contaminates the fluid and blocks the filters and strainers. Contaminated oil and clogged filters/strainers can result in overheating or clutch damage, eventually leading to complete failure of the all-wheel drive system.

Regular maintenance ensures that the system functions as intended, enhancing your driving experience and preventing more significant issues that could be costly to repair in the future.


The specific procedures and requirements for a Haldex service can vary depending on the Volkswagen or Audi model and year, but here is what a typical service includes:


Skilled technicians, like us, use advanced diagnostic tools to check the Haldex system for any issues, ensuring it functions as it should.


If any components of the Haldex are found to be faulty during the service, they will be repaired or replaced to keep your VW and Audi in excellent condition.


The Haldex system relies on specific oil to function correctly. Over time, it can become contaminated or break down, reducing the system’s efficiency. A clogged or dirty filter can also harm the flow of the oil. Regular oil changes using genuine Volkswagen Group Haldex oil and filters helps to maintain the all-wheel drive system.

For Generation 1 and 2 Haldex systems, it’s recommended to change the oil at 20,000 miles and perform both an oil and filter change at 40,000 miles. This should then be changed at every 20,000 and 40,000 miles going forward.

For Generation 4 and 5 Haldex systems, they don’t require an oil filter change and, currently, only need an oil change every three years.

Can you use any oil in the Haldex System?

No, you should stick to the genuine Volkswagen Group Haldex oil recommended for your vehicle. Haldex oil isn’t designed for lubrication, it’s meant to create friction for the clutch plates. Using any other oil could cause a complete loss of rear-wheel drive, essentially turning your car into a front-wheel drive.

How much does a Haldex oil change cost?

The price depends on your vehicle’s system. In most Haldex systems, there’s a filter to catch particles, but newer models use an oil strainer at the pump which requires different maintenance.
