Disco 4 P1247-00 low boost pressure

Over 200k miles now. Previously had secondary turbo actuator faults, ‘fixed’ with replacement diverter valve and poking at the secondary turbo actuator itself (last year).

Now has a pronounced hiss on acceleration that sounds like it’s from the air vents, smell of exhaust gas in cabin, some exhaust visible seeping from back of engine on start-up.

With this is an occasional restricted performance condition. Nothing picked up by GAPIID, but oddly the Foxwell NT680 shows P1247-00 low boost pressure.

I assume this is a leaking EGR crossover pipe, and a body off job. Could anyone confirm this/suggest anything else, and could @disco_mikey fit this in sometime if not?

Cheers
Andy

thats what my disco turned out to be, main crossover pipe and whilst they done it change one of the EGR pipes, they didnt remove the body either! the cost was expensive £1950, 8 hours labour the parts were just over £700
