Technical product information
Bentayga Hybrid - Distance covered when in electric mode is not as expected

Transaction No.: 2061044/4

Customer statement / workshop findings
Customer reports the Hybrid E-range (Electric Driving Range) does not achieve the expected distance.

Technical background
VERY IMPORTANT: Please ensure all guidelines within the repair manual are strictly followed before and whilst
conducting any work on vehicles with a High voltage system
Electric range can depend on multiple factors, e.g. driving style, road gradients, ambient temperature, use of heating / cooling functions, and the
use of other electrical consumers on the vehicle
The tests within the Measure section should be carried out (Subject to a genuine customer complaint) to check/confirm that the vehicle is
operating correctly and being used efficiently
By completing the checks within the Measure section, it should then be possible to determine that the vehicle is operating correctly and within
specification
The customer’s Home charging equipment should be used when conducting the Measure section checks

Production change
Not applicable.

Measure
1. Check the Intelligent accelerator pedal settings (Driver assist systems > Accelerator feedback) and take a photo (see Figure 1)
TIP: Ensuring the visual and haptic assists are ticked/checked encourages efficient driving

Figure 1
2. Check the Driving statistics (EV Drive menu > Statistics) and take a photo (see Figure 2)
TIP: This shows the visual indication of the proportions used when driving on zero emission in relation to the use of the Com bustion engine

3. Check the long-term memory driving statistics in the DIP and take a photo (see Figure 3)

Figure 3
4. Carry out a full diagnostic sweep and clear and resolve all DTC’s if necessary
5. Check that the High Voltage charging system is operating correctly NOTE: The customer’s Home charging equipment should be used during
the testing of the charging system
VERY IMPORTANT: A check should be made that the Home charging current is set to maximum.
6. Referring to Figure 4 - Read the following measured values in the Gateway (address 0019) using ODIS: IDE09075: Calculation, basic average
values
IDE09076: Calculated filtered remaining ranges internal

Figure 4
7. Reference the highlighted values, the ‘Range average consumption, electrical value’ is the average electrical range is miles, and a figure
above 24 miles is expected. NOTE: The Electric Range WLTP test figure is 39 km or 24.23 miles.
NOTE: The ‘Average current load profile provided’ is used to predict the available energy of the battery and can vary depending on driving
styles.

Warranty accounting instructions
Should the vehicle be found to be operating to specification, warranty claims must not be submitted
