Many thanks gents – it was as you said. P00PB code and limp mode sorted. The problem is chassis rubbing through the intercooler hose. It will happen to all vans eventually….
To guide others this is the location of the hose and rubbing point. Check yours now. Mine went at 130,000 miles

This is the hose. Almost £100 (yes really) from Ford. I managed to get one for £30 on Fleabay
It is a very simple DIY repair with no surprises using only a flat blade screw driver. Unscrew the two jubilee clips and ease both ends off. The turbo one is fiddly but just needs patience. Cleanliness is vital. Anything left in the hose will go straight into you turbo….
Top tip. It will go into limp mode on a Saturday or Sunday when Ford are shut. Take the hose to your local tyre repair depot and ask them to glue a puncture repair patch over (not inside where it can be sucked into the turbo) the hole. It works. I’ve currently done 500 miles whilst I wait for the hose.
