In an Audi S3, one of the most frequently encountered issues with the haldex system is typically the complete failure of the pump. If this occurs, you will experience a loss of rear wheel drive capability in your vehicle. The haldex system in the Audi S3 functions by transforming the front wheel drive A3 platform into an all-wheel drive system through a combination of a computer and pump mechanism that directs power to the rear wheels. Any malfunction in either the pump or the computer will result in a loss of all-wheel drive functionality. Moreover, the haldex system is prone to understeer problems due to its slower responsiveness compared to a standard all-wheel drive setup.
