Got a Golf GTI and noticed tonight that my rear carpets and front passenger carpets are wet .Any ideas where this might have come from I know we have had a lot of rain lately but ?
Most likely suspect is- Damaged or missing door membranes -is yours a 5 door? Pop your door cards off and have a look If they are OK look elsewhere- Failed seals on your tail lights -do you park on a slope ar$e up? VW apparently still do the seals or silicon seal for a quick fix. or Blocked sunroof drains -Do you have a sunroof? This can be a bit of a pain, carefully clear out the front & rear drains with speaker wire I would recommend doing a bit more research especially if its sunroof, apparently its a world of pain if you slit or disconnect a drain tube.
