Try this link as a starter.

A split top inter-cooler hose is a favourite failing. after a clogged EGR valve.

google, x-type jaguar black smoke and see what else might be an issue.

Inlet manifold probably needs a good clean

As mentioned, EGR hose which sits between EGR and MAP may have split, remove using 7mm socket on jubilee clip and examime for splits, press hose all round as some splits are not immediately obvious

Alternatively, hose between MAP and Intercooler, jubilee clips corrode and break

Lastly, but least likely, check the boost hose between turbo and Intercooler for splits
