Is Haldex only on AWD?
Haldex is a part-time all-wheel-drive (AWD) system that automatically powers all four wheels only when necessary. It’s mostly used on vehicles that operate primarily in front-wheel-drive (FWD) mode. Haldex is a mechanical clutch coupling attached to the rear differential of a vehicle that allows a variable percentage of torque to be sent to the rear axle. The Haldex system was designed for transverse mounted front wheel drive vehicles in order to offer 4-wheel drive when required.Haldex is a clever, efficient AWD system that offers extra grip and stability without wasting fuel. Whether you’re driving in the city, cruising on the highway, or braving wet or icy roads, Haldex has your back.The term Haldex coupling refers to a multi-plate clutch according to the design of the Swedish company with the same name.

The Haldex pump provides oil pressure, which helps the clutches activate rear wheel drive when required. Without this, you could get into trouble off-road. If the filter or oil strainer clogs up, the oil could become dirty and ineffective.Regardless of model, your vehicle will require regular haldex oil and filter changes just like your engine does. As a general rule, your haldex oil should be replaced every 20,000 miles and the filter, if you have one, replaced every 40,000 miles.
What is Haldex in Audi?
The Haldex system automatically distributes power between the front and rear wheels depending on slippage, but normally sends 95% of the power to the front wheels. Haldex is a part-time all-wheel-drive (AWD) system that automatically powers all four wheels only when necessary. It’s mostly used on vehicles that operate primarily in front-wheel-drive (FWD) mode. Less frequently, it’s employed on rear-wheel-drive vehicles to send power to the front wheels.The Haldex limited wheel slip differential system may be largely inactive in neutral driving conditions but may activate when any wheel slippage is detected.The second generation of Haldex coupling is an electronically controlled permanent 4×4 system with a Haldex differential calculating how much drive should be directed to the rear wheels.At its core, 4MOTION is Volkswagen’s name for its all-wheel drive system. In gasoline and diesel-powered vehicles, it typically uses an electro-hydraulic centre differential known as a Haldex coupling.
