Hello everyone, first post on Briskoda.
Bought a 2004 Octavia Mk1 a few months ago and whilst the car is mechanically sound, there is an issue with rainwater leaking into the car on the passenger side. After a heavy bout of rain it's a literal puddle. Thankfully the shop vac came in handy to suck most of it up.
I looked through the forum and have already checked the sunroof (drains free running via testing with a Fairy bottle) and had a look near the pollen filter (no debris or damage to the grommet).
Using the trusty watering can to try and establish the cause, it appears (hopefully) to be the rear passenger door.
It looks like the door was taken off at some point (prior to me owning it) and it's not been tightened correctly. I've added some pictures below show what I mean, and the mildew/mold along the seal suggests water is getting in where it shouldn't.

How would I go about fixing the door so it aligns properly?
Thanks!
