Went to it to come home, very slow starter as if the battery was flat. Turns out the battery wasn't flat as jump leads made no difference.
Other clue was the glow plug light came on much shorter than usual.
Got it started this morning by using a screwdriver across the starter terminals. Since then it has started normally on the key several times with a few hours in between.
I'm thinking ignition switch or glow plug relay? Anyone got any experience of this issue?
Thanks in advance
