VW Bora 4mo leaking issue

[forsakencrew]

Update: replaced oil pressure switch and dipstick tube o-ring and leak disappeared. Had to jump start it with the all mighty Toyota as the battery had died (she started first go), then the car cut power and turned off after idling for 5 minutes. I went out to buy a new battery, installed it and she wouldn't start. It turns over, but doesn't start. Any ideas?

Edit: started first go after checking the wiring for the crank position sensor. All running well.
