I've been away this week and the MK4 was used as a runaround for a few days by my brother. He last drove it on Wednesday with no issues and now there is nothing when turning the key (tried both).

The battery is fine, lights etcs work, but no click and no starter. The dash warning lights does not come on at all when turning the key.

Anybody have any ideas?

Ignition switch related? Loose earth? Anything?
