The Haldex All-Wheel Drive Coupling (also known as the AWD Coupling) is the heart of VAG’s 4Motion and Quattro systems.

Developed by BorgWarner, it uses an oil pressure activated clutch pack and electronic control module to send power instantly between the front and rear axles, providing traction, cornering stability, and improved handling in all conditions.

It’s also used in some Land Rover, Saab, and Volvo models, as well as the VAQ front differential (torque splitter) fitted to certain high-performance FWD VAG vehicles.

Benefits of a healthy Haldex system:

• Improved traction & stability

• Intelligent torque distribution

• Enhanced cornering performance

• Smoother power delivery under load

When VAG first introduced these systems, dealerships incorrectly marketed them as “sealed for life.”

In reality, the manufacturer BorgWarner recommends servicing every 20,000 miles or 24 months (2 years) — regardless of age or model.

Skipping these intervals can lead to:

• Pump or controller failure

• Blocked filters and strainers

• Overheating clutch packs

• Full differential or coupling failure

JCR Leeds follows BorgWarner’s official maintenance guidance, not the dealer myth.

Most main dealers only drain and refill the oil, that’s it.

On older systems (GEN 1–4), they’ll even deny the filter exists (it does, we fit genuine BorgWarner replacements).

On GEN 5 systems, they’ll replace the oil but won’t clean the strainer gauze on the pump, meaning they’re just circulating clean oil through a dirty filter.

It’s a bit like “going to the toilet and not wiping afterwards.”

Clean oil through a dirty filter means premature pump failure, something we repair every week.

At JCR, every Haldex service is done properly:

• Filter replaced or gauze cleaned

• System flushed

• Pump operation verified via ODIS/VCDS diagnostics

• Digital service record updated with Audi, VW, SEAT, Cupra and Škoda

Your AWD drivetrain includes three key components:

• Haldex coupling (rear differential unit)

• Front transfer case

• Rear final drive

While the Haldex requires servicing every 20,000 miles / 24 months, we recommend the front transfer case and rear final drive are serviced at least every 50,000 miles to prevent wear, noise, or bearing damage.

• OEM transfer case & rear diff fluid changes

• Magnetic plug (Racingline)

• Seal and breather inspection

• Optional combined service with Haldex for full system protection

As the UK’s go to Haldex experts, we offer:

• Live pump activation & Haldex data logging
