Torque Max. to Front Wheels
Shows you the actual clutch pressure , converted to the max. transferable torquemaximum torque that can be transmitted. This is NOT the actual torque transmitted, this is but the max. maximum torque the clutch can forward transmit at a given pressure.
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.

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

Lifetime Workload Clutch pack L1/L2/L3
Those These are the lifetime workload counters of for your transfer case clutch pack. The higher the workload, the higher the wear in on your clutch pack. The counters are split in 3 divided into three classes, which are counted independently:
L1 (left one) is the lowest power -class level and is usually the one where the most workload happens in. This is slip wear occurs. These slips and wear occur during normal drivingeveryday riding, turning at junctions, etc. (Power power class 0-200 Wattswatts).
L2 (200 to 2000 Wattswatts) and L3 (> 2000 Wattswatts) are the high ones, which get upped are increased when the Thermal Stress thermal load on the Clutch clutch is already raisedhigh.
If the L3 value being is high, is an indication for this indicates heavy use in the past. The complete total workload is calculated by summing up all 3 three counters.
Those counters do not get reset with an oil-service, 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 total workload on E-Series series cars and 50 kWh on F-Series carsseries cars.
