My Skoda Octavia has had multiple issues since the emissions fix - is it related?

My 2010 Skoda Octavia 1.6 TDI has had numerous faults after the emissions fix. Erg valve has been replaced, injectors were replaced. The light has come back on now and they say the turbo and intercooler have failed, but I must pay. Is this linked to the fix?
It's normal for a worn EGR and for worn injectors to fail soon after the fix. The injectors have to do 50 per cent more work. They are related failures, but the turbo and intercooler aren't.
