Timing belt broken, valves okay?

Hello,

This is about a friend's A4 B9 with a 2.0 TDI DTPA engine (204 hp, 4-cylinder). In a not-too-severe accident, the hood was pushed down onto the timing belt sprocket, causing the timing belt to tear. In many 2.0 TDI engines, this can lead to the valves contacting the pistons. Is this also the case with this engine? Given that this 4-valve engine has valves with less lift than the older 2-valve engine, and that the valves are positioned vertically (not at an angle) relative to the piston, I could imagine that this might be different in this case.Does he know that for sure?
And if there's a possibility of contact, has anyone had relevant experience regarding the consequences of this type of engine?
Letzte Frage klingt banal, aber ich hatte vor vielen Jahren bei meinem 1,9 TDI (2-Ventiler) Folgendes: gleicher äußerer Schaden, habe mühselig den ganzen Z-Kopf abgebaut - und dann war da innen außer minimalen Kontaktspuren gar nichts. Alle Ventile noch dicht. Lediglich 3 Stößel waren merklich eingedrückt und wurden erneuert. Und dafür hätte ich mir den aufwändigen Kopf-Ausbau schenken können... Motor lIt should easily last another 150,000 kilometers without any problems.
Therefore, I am hoping to find specific experiences here regarding belt failures with this newer engine type.

Hello.

Bei vielen 2,0 TDi kann es dabei zum Kontakt der Ventile mit einem Kolben kommen.

Diesel engines, due to their high compression ratio, are practically never "free runners."

The engine is likely scrap, especially if you don't have much time; it's better to get a replacement engine.

Look down and see.

Measure the piston protrusion.
