What is mind blowing about it? Every single generation of VW/Audi 4 cylinder engines since 2001 have had a systemic issue which has caused premature failure.
2001-2005 A4 1.8T oil sludge
2005-2008 A4 2.0 TFSI faulty high pressure fuel pump design, camshaft failures
2008-2014 A4 2.0 TSI faulty pistons (oil consumption) and faulty fuel injectors which stick open (cracked rings).
Nobody will ever know for certain what caused the damage, but the probability is very high that a fuel injector was stuck open, excessive fuel was being compressed, piston ring cracked due to the pressure (hydrolock).
It is not very likely that the tune would cause the issue that you described.
