My father's 1989 petrol, watercooled type 25 has an intermitent oil pressure warning light/buzzer problem. it comes on after a little while, but can go off when changing gear. Oil has been changed, oil filter has been changed, oil pressure sensors have been changed, coolant thermostat has been changed, but it still happens. if he stops and waits a little while it eventually goes off....
Our VW camper garage with 20 years experience can't find the reason.
Any ideas would be great thanks.
