Audi 3.0tdi crank pulley failure

[Lotobear]

My pals Q7 suffered this last night - 2013 on around 95k miles.

I have a 2013 C7 Allroad with the same engine on 73k miles. Does anyone know if this model is vulnerable as well?

I've visually checked and felt the front of the polymer infill and it feels fine but I can't access the rear of the pulley.

Should I be replacing this as a matter of course?

Cheers

I've seen 2 or 3 go on that engine. Not "common", but yes it can happen.
