Ok guys,
I have a problem, Over the last couple days after a journey I park up do what I have to do go back to car then It wont start. There is no ticking over nothing, battery light and EPC light comes on. I turn off take the key out try a few more times and after 4 trys or so It will start as usual The car drives great so I have no idea

Any suggestions? This dosent happen everytime I restart the car. Maybe once or twice a day over last couple days.
This is a golf mk4 1.8t btw.
