Haldex servicing for VW & Audi vehicles

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

What is the Haldex system?

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 4-wheel drive. This system is designed to improve traction, handling and stability to ensure a safer and more controlled driving experience. If your wheel starts to spin or understeer, Haldex will kick in to provide rear wheel drive. 

How does the Haldex system work?

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. 

Why do you need to service the Haldex? 

Servicing the Haldex system on a VW and Audi is essential to maintain its performance, safety and reliability. Regular maintenance ensures that the system functions as intended, enhances your driving experience and helps prevent more significant issues that could be costly to repair in the future. 

What is involved in a Haldex service?

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:

Oil and filter change

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 system’s performance.

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.

Diagnostic Check

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

Repairs and Replacements

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