vw polo 1.9sdi 2005, water leaking in from the rear area

[pauljsmith123456]

Hi, just had to take one of the rubber bungs out from the spare wheel floor to drain water from it, it was a good 3" deep of water, also the boot area floor is damp and also the rear seats, roof lining dry and everything else till you get to the floor area, i've tried sitting in the boot and someone with a jet wash spraying but that didnt show anything, any help muchly appreciated thanks, paul

A smoke test is the preferred method to accurately diagnose where the water is getting in

If you have a sunroof then this may be the cause if the drain bungs and tubes are blocked
