Hi,
First, this vehicle isn't offered in the US, so I have no technical information. However, I will try to help.
Has the fuel pressure been checked? Low fuel pressure can cause symptoms like this to occur. Also, even a plugged fuel filter.
Here is a link that shows how in general to check fuel pressure:

Check the pressure and see if it is within spec.
Let me know what you find.
Joe
