Did the belt break or fail? It is an interference engine and there may be valve damage.

No I changed head gasket. I can see the mark on the pulley, but what does it align with?

There is no backing plate only a plastic cover with no markings this is different to the Jetta or Golf that is why I need advice.

The manual way is to remove the valve cover and look at number four cylinder. It has to be on valve overlap which means the intake and exhaust are open at the same time the exact amount of lift. You can use a level on the lobes to verify.
