Audi Quattro & VW 4Motion: A Guide to Maintenance and Common Issues

Quattro - Maintenance

The ultimate all wheel driving experience can be found in Audi’s legendary Quattro system and Volkswagen’s cutting-edge 4Motion AWD system.

Proper maintenance is essential since with great power comes great responsibility. In this post, the experts at Reflex Tuning explain how to keep your Quattro AWD system in top shape, as well as provide insight into Volkswagen’s 4Motion technology.

When combined with the vehicle’s anti-lock braking system (ABS), the Quattro and 4Motion systems provide the highest level of handling and control possible. This is why Audi and VW are at the top of the list when it comes to vehicles that offer the safest winter driving experience.

Stay on top of servicing your fluids 💧

Drivetrain fluids need to be changed regularly. The recommended interval will depend on which AWD system your vehicle has. Typically the service interval will range from 25,000-40,000 miles or every 3 years. For the AWD system to work as intended, the fluids must remain as new as possible. Because most of the drivetrain systems only hold between .8-1.25 liters of fluid, the fluid become contaminated rather quickly. Friction and wear are negatively impacted by cleanliness and fluid levels, respectively.

Tire condition and tread allowances 🚗

Keeping your tires in good shape is essential for the best possible performance from your AWD system. Make sure the tread on all of your tires are within 2/32nds of each other. If the difference in tire measurements are vast;y different, then the rotation of each wheel will not be the same. This can lead to premature failure of multiple areas within the drivetrain system.

Although all-season tires are okay for most people who live in NH. Dedicated snow tires coupled with the power of all-wheel drive, are the safest way to travel. We offer seasonal tire and wheel storage for those who change their tires seasonally.


Straight and True Wheels 🔧

For the best tire life and AWD performance with both Quattro and 4Motion, regular wheel alignment and balancing are musts. Uneven tire wear and AWD system problems can be avoided with routine maintenance checks. Tires should be rotated every 5k miles. Tire balance and wheel alignments should be done every 15k miles or annually.


Common Problems of the Quattro and 4Motion 📝

The most common failures we see on the Audi and VW AWD systems are rear differential failures and Haldex pump failures. By properly servicing your drivetrain fluids, you will avoid costly repairs down the road.
