Door Lock Problem

[WorkInProgress]

I've got my drivers door card off and managed to bump into the door lock pin which snapped a small white clip. This clip I think locates the door lock pin into where it's meant to go, any ideas how I would go about getting a replacement? I assume Audi would want to sell me a whole mechanism

Apparently you can cable tie the rod/pin in place so I think I will give this a go
