I'm guessing you still need to depress the brake pedal at the same time?
Is this 'trick' in the owners manual or workshop manual?
I'm kind of having a similar issue at the moment but I am getting an audible 'click' when pressing the start button. Replaced the battery with a new H8 AGM unit which must have been on the shelf for a little while as was at 12.4v. LR wouldn't start so gave her a jump and after a couple of attempts she fired up. Just took her for a good drive to get the new battery charged up and just leaving her be for a little while.
Stupid question number one - Does the drivers door need to be closed to start? Reason I ask is that when I was jump starting she would only 'click', I then closed the drivers door and voila she kicked over!?
Sorry to hijack the post but similar theme.
