[Crafter daua]

I have a vw crafter daua
Sometimes it starts, sometimes it doesn't
Code p0562 appears
I've changed the battery and it's still the same
It works then when I stop the van and try to start it again it doesn't start and it can start in 3 hours or 2 days.
What could it be? I'm going mad

Have you checked the earth connection between the engine and chassis?
I had a similar problem with a vehicle many years ago because the chassis connection had a ton of corrosion on it

When you say it doesn't start - is it completely dead, does it crank but nots start, etc?
