I've found a parasitic draw on my 2002 Xtype, it's the 50amp fuse, that sends power to the interior fuse box, now that I've found the draw l don't know what to do next, any help would be really appreciated.

 

Welcome to the forums Tich,

TECHNICAL questions are best posted in the relevant MODEL forum. I've moved the other copy of this question to X-Type forum for advice from members with the same model. Here's the link to it:

As a basic next step regardless of model, you need to go to that interior fuse box and further isolate the issue.

Depending on your car this is possible by measuring voltage drop across fuses or removing fuses. The complexity comes in getting to its sleep state and how your actions might stop it getting or staying there.
