xDelete - xDrive Live Data


To reach the Live Data Screen, click on your car on the main page and click the 3 white dots on the top-right of the Screen. From the Misc. Menu select “Live-Data” while being connected to your car, via the same supported hardware connection being used for flashing.

xDelete now continuously reads important performance information from your transfer case, including the following:

  • Torque Max. to Front Wheels

  • Thermal Stress Clutch Pack

  • Temperature Actuator E-series only

  • Position Actuator:

  • Vehicle Speed E-series only

  • Lifetime Workload Clutch pack L1/L2/L3

  • Engine RPM E-series only


Torque Max. to Front Wheels

Shows you the actual clutch pressure, converted to the max. transferable torque. This is NOT the actual torque transmitted, this is the max. torque the clutch can forward at a given pressure.


Thermal Stress Clutch Pack

As soon as there is a relative movement between 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.

E-series Delivers exact values.

F-series No precise value available, but 3 states.

  • Normal (0-50% Stress)

  • Level 1 (51% - 80% Stress)

  • Level 2 (81% - 100% Stress)

The App will flash yellow and red, when reaching Level 1 and 2.


Temperature actuator

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

E-series Delivers exact values.

F-series No precise value available, but 4 states.

  • Normal (0-30% Stress)

  • Level 1 (31% - 50% Stress)

  • Level 2 (51% - 80% Stress)

  • Level 3 (80% - 100% Stress)

The App will flash yellow, orange and red, when reaching Level 1-3.


Lifetime Workload Clutch pack L1/L2/L3

Those are the lifetime workload counters of your transfer case clutch pack. The higher the workload, the higher the wear in your clutch pack. The counters are split in 3 classes, which are counted independently:

  • L1 (left one) is the lowest power-class and is usually the one where the most workload happens in. This is slip and wear during normal driving, turning at junctions etc. (Power class 0-200 Watts)

  • L2 (200 to 2000 Watts) and L3 (> 2000 Watts) are the high ones, which get upped when the Thermal Stress on the Clutch is already raised.

  • L3 value being high, is an indication for heavy use in the past. The complete workload is calculated by summing up all 3 counters.

Those counters do not get reset with an oil-service, 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 cars and 50 kWh on F-Series cars.
