@Lordie; if you don’t carry rear seat passengers or any loads on the back seat, have you checked your headlining for water staining above the rear seat that had these white marks on? I’m wondering if the rubber gasket between the roof panel and aerial might have failed, allowing water in, saturating the roof lining and then dripping onto (and soaking) the rear seat backrest, although if it happened only once that’s probably not the cause.
With the staining on the front centre armrest; is it possible that a front seat passenger or driver could’ve had something damp on their sleeve that transferred to the armrest?
Condensation on the inside of the windscreen during the colder months may be a consequence of when the ambient air temperature drops below the dew point, causing moisture to form. However, if you’re getting ice on the inside of the screen and the car regularly steams up inside, ignoring the staining on the seats, these signs might be an indication of a separate water ingress problem. Check all the usual potential sources of water ingress and telltale signs;
- blocked pollen filter
- if you have a sunroof, blocked sunroof drain pipes
- failed door speaker seals
- failed or damaged rubber door and tailgate seals
- failed or damaged roof aerial gasket
- broken paintwork between tailgate hinges and hinge mounting points onto the bodywork
- failed seals between rear light clusters and bodywork
- perished grommet on the tailgate hatch handle drain tube (allowing water to drain into the tailgate cavity, which then empties into the boot)
- water in the spare wheel well
- damp carpets
- leaving wet or damp clothing in the car
Ignore the marks on the arm rest, they're just general marks that have built up over time. But the rest of the white marks were very strange and small patches appeared throughout the car dotted around on every seat seemingly overnight.
One thing you have to bare in mind is that a tree fell onto the roof of my car which could be part of the cause. Although the very thin layer of ice on the inside of the windscreen sometimes was happening before that happened anyway. And I haven't noticed anything worse than before it happened
I've also always had an issue where if I drive the car with the heaters on, park up, then come back an hour later and start the engine the windscreen goes from clear to rapidly misting up in 10 seconds. So I have to very quickly hit the Max fan button before the whole windscreen mists up and I can't see where I'm driving. Once I hit Max it clears in a few seconds. I assume that may be down to some air filter inside the car?
Thank you very much for the list!. I haven't noticed a single thing obvious so once we get some good rain I'll go out and check though everything you listed
