Thanks kev. Heard the 2.7 suffers from injector a d timing chain issues.
I've had a quote to rebuild my engine for £2200. But then I'd have to get a new turbo, injectors etc. This company:

Very tempted with this option but do a turbo upgrade from the 3.0TDI which can be converted to work along with upgrade (race injectors), FMIC, egr blank, aluminium rad, sports exhaust and then remap on the new engine.
Think this could give best of both worlds of new engine and extra performance.
I'd be adding a new clutch and dmf. Very tempted to fit a new injection pump.
