So after the untimely demise of my much loved 2012 Westie, I have entered into the world of L405 ownership with a 2015 4.4 VSE. First impressions very favourable, one owner car with 66,000 miles from main dealer with 4yr warranty at a lower price than other non main dealer garages were offering. Prices appear very random at the moment ! Anyhow a lovely thing to drive and a pleasant update on the L322 very spacious and airy cabin with the pan roof and Ivory leather. Only slight niggle so far is the electric tailgate that seems to have a mind of its own sometimes opens all the way, sometimes halfway, sometimes won’t close all a bit random, guess it will be my first warranty claim. 2015 L405 Range Rover 4.4Sdv8 Vogue SE, Baltic Blue, Ivory

Look in your handbook it may just be its lost its memory

TAILGATE OPENING HEIGHT

The maximum opening height for the tailgate can be set as required. Setting a maximum height is useful in parking areas with very low roofs, or just for ease of use.

To set the maximum opening height as required:

Open the tailgate to the position required as the maximum height. Press any opening or closing button to stop movement at the required position. The final position can be achieved manually, if required.

Make sure the tailgate is stationary for at least 3 seconds.

Press and hold the close button for 10 seconds to set the required opening height.

Press a close button to close the tailgate. Open again to check that it opens to the required height. See OPENING AND CLOSING THE POWERED TAILGATE.

The maximum opening height is now set.

NOTES
If, after performing step 3, the tailgate closes automatically, the required height has not been set. Repeat the process, making sure that all steps are adhered to.

To reset the maximum opening height, repeat the process, but fully open the tailgate before pressing and holding the tailgate close button.

The powered tailgate may lose its position memory if there are multiple object detections, or if the battery voltage is low. Powered operation may be inhibited.

To reset the tailgate's opening height:

Manually close the tailgate.

Press a release button.

Allow the tailgate to power fully open, or to the previously set position.

Press and release the close button.

Allow the tailgate to power-close fully.

The position memory is now restored. 2018 SE SDV8 4.4 Byron Blue
