Why not simply change glow plugs and clean turbo geometry? All DTC's should be gone if car is running original software on ECU.

Then i guess DTC removing is not the way, you still have a problem there, you should not simply ignore it. At least is what i think. ;)

Glow plug dtc's are usually caused by wrong glowplugs (only fit NGK) The wrong plugs will blow the controller. you probably need new glowplugs and a new controller. Have you stripped and cleaned the turbo. It must be stripped. Spraying cleaner in to the turbocharger is a waste of time.
