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. A Haldex oil change/service should be carried out every 20,000 miles for best results. However, this can change depending on the model and age of your vehicle. For vehicles without a filter, this may mean booking a Haldex service every 10,000 miles.The Haldex oil is a non-lubricative oil to promote friction of the clutch plates and using any other oil can result in a total loss of drive from the rear effectively converting your car into a front wheel drive.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.When it comes to maintaining your VW, SEAT or Audi, Haldex oil changes are essential. Consider them to be an investment in the overall health of your vehicle. By preventing oil contamination and maintaining proper lubrication, you reduce the risk of costly system repairs or replacements.The manufacturers recommendation for servicing is oil change every 20,000 miles & filter change every 40,000 miles however, in our opinion, this should be done on an annual interim service depending on your driving style and which generation Haldex System is fitted to your vehicle.
Which Audi cars use Haldex?
Haldex is used by Audi on the quattro versions of the Audi S1, Audi A3, Audi S3, and the Audi TT. The Haldex Gen 5 all-wheel drive coupling is featured in most high-performance VAG vehicles (Audi, Skoda, VW) produced between 2012 and 2021. Q3 (2012 – 2018). S1 (2014 – 2018). A3 (2012 – 2016).Volkswagen uses Haldex AWD on its Tiguan and Golf R, and corporate cousin Audi fits it to some of its smaller cars, including the Q3 and the TT. Other brands that have used Haldex AWD include Cadillac, Ford, Saab, and Volvo.Audi employs the Haldex-based Quattro system in a range of models, especially those built on platforms shared with other Volkswagen Group vehicles, such as the Audi A3, TT, and certain Q models.First generation – 1998. The Haldex Coupling made its first appearance in the Audi TT, Audi S3 8L and VW Golf with an electronically controlled hydraulic-mechanical all-wheel drive concept. This system attempts to engage the rear wheels when the front wheels start to slip.
How often should Audi Haldex be serviced?
When should I book a Haldex service? A Haldex oil change/service should be carried out every 20,000 miles for best results. However, this can change depending on the model and age of your vehicle. For vehicles without a filter, this may mean booking a Haldex service every 10,000 miles. Improved Performance A fresh Haldex oil replacement enhances your vehicle’s all-wheel drive system, resulting in improved traction and drivability. Whether you’re cruising down the motorway or manoeuvring through challenging terrains, you’ll experience a smoother and more responsive ride.The Haldex oil is a non-lubricative oil to promote friction of the clutch plates and using any other oil can result in a total loss of drive from the rear effectively converting your car into a front wheel drive.What happens if you don’t service Haldex? 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.A Haldex oil change/service should be carried out every 20,000 miles for best results. However, this can change depending on the model and age of your vehicle. For vehicles without a filter, this may mean booking a Haldex service every 10,000 miles.
Is Haldex a good brand?
The Haldex system appeared in the late nineties, remaining a reliable and effective all-wheel-drive form. Its continued success stems from an effective design, but its many updates over the years have kept it competitive and ever-improving. 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.Some Haldex rear wheel differential systems are also engineered to send power towards the back wheels when the vehicle first gets underway. Many drivers prefer this setup as it helps to give additional grip, but the power will generally be diverted to the front in normal driving conditions.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.In the event of front wheels losing traction, Quattro or 4-motion activates and commands the car to apply clutches in the Haldex system to drive the rear wheels. The operation of this safety process is done via hydraulic pressure supplied by a pump called Haldex pump.
Is Haldex the gearbox?
Unlike gearboxes and independent differentials, a Haldex system features a proprietary form of lubrication. In fact, this liquid may be just the opposite of a standard lubricant in that it’s designed to promote a certain amount of friction instead. MOTION is Volkswagen’s permanent all-wheel drive system, which offers great grip on the toughest roads and in the worst weather (through rain, snow and hail).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.Unlike traditional AWD systems that are always running, Haldex activates only when necessary, making it more efficient and fuel-friendly. In simpler terms, it’s like having a “smart” AWD system that steps in only when it’s needed, saving energy without compromising on control.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. Under normal driving conditions, most of the power is sent to the front wheels for efficiency.
