Water in spare wheel well?

[pesa1]

I recently found some water in the spare wheel well on my N16 but can't see anywhere it could've leaked, the boot mat was dry so I wondered if anyone knew places underneath where it coud've leaked?

Most probably from around the rear lights.

Sealant around the rear lights where they meet the body should cure the problem mate.
