febi released another technical video, this time related to the Haldex Coupling Oil and Filter Replacement for Audi TT.
In this video we replace the Haldex Coupling Oil and Filter on an Audi TT equipped with the first-generation Haldex coupling using febi Kit 181845. This Haldex coupling is also used in different Volkswagen Group vehicles.
The Haldex coupling is an electro-hydraulic system attached to the rear differential which allows the vehicle to switch between front and all-wheel drive as required.
This process creates a high degree of friction between the metallic components within the system, which degrades them over time. Therefore, it is recommended to replace the oil and filter at regular intervals.
