To access the Live Data screen, click on your car on the main page and click on the three white dots at the top right of the screen. From the Misc. menu, select "Live Data" while connected to your car.
xDelete will now continuously read important performance information from your transfer case, including the following:

Torque

to Front Wheels

Shows the actual clutch pressure converted to the maximum torque that can be transmitted. This is NOT the actual torque transmitted, but the maximum torque the clutch can transmit at a given pressurewith the current pressure applied.

Thermal Stress Clutch Pack

As soon as there is a relative movement between the Front and Rear wheels, slip occurs within the clutch pack. This slip is converted into heat and wear. The xDrive ECU calculates the resulting clutch- temperatures and converts this into a maximum percentage of the permissible temperature. As a rule of thumb, you should not exceed 50% thermal load for extended periods.

When relative movement between the front and rear wheels occurs, slip occurs within the clutch pack. This slip is converted into heat and wear. The xDrive ECU calculates the resulting clutch temperatures and converts them into a maximum percentage of the permissible temperature. As a rule of thumb, the thermal load should not exceed 50% for long periods.

• Normal (0-50% Stress)

• Level 1 (51% - 80% Stress)

• Level 2 (81% - 100% Stress)

Temperature actuator

The spindle driven by the actuator is immersed in oil, indicating the temperature.
The temperature should not exceed 90°C (~ 195 °F).

• Normal (0-30% Stress)

• Level 1 (31% - 50% Stress)

• Level 2 (51% - 80% Stress)

• Level 3 (80% - 100% Stress)

Lifetime Workload Clutch pack L1/L2/L3

These are the lifetime workload counters for your transfer case clutch pack. The higher the workload, the higher the wear on your clutch pack. The counters are divided into three classes, which are counted independently:

• L1 (left) is the lowest power level and is usually where the most wear occurs. These slips and wear occur during everyday riding, turning at junctions, etc. (power class 0-200 watts).

• L2 (200 to 2000 watts) and L3 (> 2000 watts) are the high ones, which are increased when the thermal load on the clutch is already high.

• If the L3 value is high, this indicates heavy use in the past. The total workload is calculated by summing all three counters.

An oil service does not reset these counters as they reflect clutch pack wear, not oil deterioration.
A single clutch pack is good for around 100 kWh of workload on E-series cars and 50 kWh on F-series cars. For G-Series cars we are still collecting data and will release guidelines at a later stage.
