Tamsinwonder Posted March 15, 2020 Report Share Posted March 15, 2020 (edited) Hi I have a vw lupo which is leaking through the passenger door. We've took the door cards off and poured water down the window and there's a lot of water coming through but we've changed the window seal and it's still doing the same. We are at a loss. Please help Edited March 15, 2020 by Tamsinwonder Edit for tags Quote Link to comment Share on other sites More sharing options...
LR5V Posted March 15, 2020 Report Share Posted March 15, 2020 Window seals are not perfect - there should be a sealing membrane behind the door cards that gets destroyed from maintenance - common VW problem not just on the Lupo Quote Link to comment Share on other sites More sharing options...
Tamsinwonder Posted March 15, 2020 Author Report Share Posted March 15, 2020 Thank you so much I'll have a look at that Quote Link to comment Share on other sites More sharing options...
C3peteo Posted March 16, 2020 Report Share Posted March 16, 2020 Butyl tape and a sheet of plastic make for a good substitute for the factory membrane. Ebay sell both. Quote Link to comment Share on other sites More sharing options...

Sausage Posted March 16, 2020 Report Share Posted March 16, 2020 Make sure the door drain holes are clear as well. Also if you park on a steep enough slope the rain pools in the door sill and gets over the rubber seals. Quote Link to comment Share on other sites More sharing options...
