I have a 2014 TFSI saloon and when I looked at the boot around the spare wheel the other day and around the battery I noticed a small amount of water, with lots of what looked like condensation as well around the battery and spare wheel. I cleaned it all up but today, 3 days later, a small amount of water is back.

Any ideas where this water is coming from and how it should be drained? Are there drainage holes somewhere that might be blocked in the boot, or is this condensation just normal this time of year? Water is clean.
