After many instances of battery drain issues on F-Pace/XE/XF vehicles JLR Canada has issued an update (SSM 74635) which is intended to solve this issue of vehicle controllers staying awake for a prolonged period of time after the vehicle is turned off.
Battery drain when dongle or any device is installed on the OBD port (with the exception of the JLR diag tool).
F-Pace / X761
XE / X760
XF / X260
JLR Canada has recently released SSM 74635 for the battery drain issue when dongle is connected in relation to the OBD devices. (See SSM notice below)
A simple update of the vehicle will allow you to connect your OBD dongle to the vehicle without any issues. If issues do persist, please let our engineering team know at email@example.com and also inform JLR Canada of the matter.
