It's time to change or repair the high pressure fuel pump.

Thanks for your reply Ife
Is it very difficult to remove the Fuel pump from the car?
I've found someone who will refurbish it for around £140.

It's not difficult, I did it.
You have to remove the pipes that go to and return from the air filter.
Better also remove the battery.
To remove the fuel inlet tube you just have to press on the plastic clip, not pry it out like they do in some videos!
Make sure no dirt gets into the fuel tubes.
It is held in place with 3 torx screws.
