Hi Guys

Im a first time poster, Ive recently bought a 2002 B5 130BHP TDI . I noticed the rear lights fogging in addition to excess moisture ont he rear screen and back windows. I investigated and found water in the spare wheel well, -i dried out but the problem is back-can anyone please advise?

-can it be coming through the boot seals or maybe a leeking bung?

Cheers
Mark
