Information
- Currently, the Porsche Doppelkupplung (PDK) is increasingly being replaced together with the transfer case.
- When checked by the supplier, the Porsche Doppelkupplung (PDK) is found to be "OK". It was mainly only the transfer case that was defective.
- => Before doing any other work, the following test steps and procedures must be observed.
Information
The "transfer case" is designed as an active all-wheel drive system that is dynamically adapted to the respective driving state.
Power transmission between the front and rear axle is controlled electronically via the "all-wheel drive servo motor (transfer case)" and the multi-plate clutches integrated in the transfer case.
=> On all-wheel drive vehicles, the drive train can become strained at low speeds and when the steering is turned sharply when "Off-road mode" is activated, depending on design.
- Under extreme conditions, the drive train can also become strained when "Off-road mode" is deactivated.
- Customers with little experience with all-wheel drive vehicles can interpret this behavior as a fault, which in turn can result in incorrect diagnoses in the workshop.
