hi,it is not mine ,it is a 2003 td6 the suspension takes miles to get to ride height the light flashes but takes ages,it doesnt seem to want to rise when stationary or takes forever has anybody have any ideas as to what is up,it doesnt sink when left overnight.

Yes, try one of those bag piping andy repair kits.
worked on mine. There's a great you tube vid how to as well.

The compressor could be at fault but check for leaks from the airbags or elsewhere first. If the leak is tucked up inside the fold of the bag the only symptoms can be it just takes awhile to rise and may not even get into off road height if selected (that's what I had). It can still sit without dropping with a hole in the air bag if it's sealed by the rubber in the fold.
Get it in off road height and check all the air bags, you'll probably hear the leak before you see it but a small leak is easier to spot by spraying soapy water on the bags as you would for a tyre puncture.

This one..
