Battery draining on T5

[Jimmi]

My friend has an 04 T5 she bought while renovating her house to move stuff about and still has it 5 years later. Apparently it keeps draining batteries, a local guy told her it’s the interior light causing the problem and “fixed it” but the fault has returned. Any ideas what this could be? I know this is pretty vague but wondered if someone had come across it before?

Not one I have seen could maybe consider putting an amp meter inline on battery to see if or where the current is being drawn from. If found to be a larger than expected current draw you could then remove fuses one by one to locate which circuit is in fault and trace the drain from that point.
