Volkswagen Haldex Service Kit (GTI Performance Pack, 40 Years, MK7.5 GTI & MK8 GTI)

Maintain your Volkswagen's electronically controlled limited-slip differential with our complete Haldex Service Kit, designed for GTI models equipped with the factory VAQ differential.

Regular servicing is essential to maintain optimal locking performance, prevent contamination, and maximise the lifespan of the Haldex clutch pack and hydraulic system.

Please Note: Only some late-model MK7.5 GTI vehicles are equipped with this Haldex system. If you're unsure whether your vehicle has a VAQ differential, please contact us with your VIN before ordering.

Kit Includes

• Haldex Filler Plug
• Haldex Drain Plug
• 850ml Febi Bilstein Haldex Gear Oil

Why Service Your Haldex Differential?

Over time, Haldex oil degrades and becomes contaminated with clutch material. Replacing the oil at the recommended intervals helps:

• Maintain consistent differential locking performance
• Protect internal clutch packs and hydraulic components
• Reduce wear caused by contaminated oil
• Improve long-term reliability

Service Interval

Volkswagen recommends servicing the Haldex system approximately every 3 years or 45,000 km, whichever comes first. More frequent servicing is recommended for vehicles driven enthusiastically or under demanding conditions.

⚠️ IMPORTANT FITMENT & COMPATIBILITY NOTICE

This service kit is designed specifically for Volkswagen GTI models equipped with the factory VAQ electronically controlled limited-slip differential (Haldex).

Correct Fluid Selection

The included Febi Bilstein Haldex Gear Oil is formulated to meet the lubrication and hydraulic performance requirements of the VAQ Haldex differential, ensuring correct clutch operation, smooth engagement and long-term component protection.

Why It Matters

The VAQ differential relies on specialised Haldex fluid to lubricate and operate the internal hydraulic clutch system. Using an incorrect oil may result in:

• Reduced differential locking performance
• Increased wear of the clutch pack and hydraulic components
• Poor torque distribution under acceleration
• Premature differential failure

Before Ordering

Please ensure your vehicle is equipped with the VAQ Haldex differential before ordering. This kit is not suitable for standard open differentials.

If you're unsure, contact us with your VIN or vehicle details and our team will gladly confirm the correct service kit for your vehicle.
