I noticed a few weeks ago that my rear passenger footwell was soaked - not so much a puddle, but when you pressed it water came to the surface. After a few days, the driver side and passenger side front were both also a bit damp.
The spare wheel well in the boot also showed signs of water.
I dried it out, put some dehumidifiers in there to double check I hadn't forgot to close my windows or sunroof or something - a few days later after some terrential rain, it was back soaking again.
It's a MK5 GTI with a sunroof. Worst part is the rear passenger footwell, but then seems to spread. Where's common for these to leak? I thought potentially sunroof but seems more further back...
TIA
