One thing to look out for. The zips on the outside have flaps of material over them to stop water hitting the zip itself, which isn't watertight.
Sometimes these get "folded over" exposing the zip directly to water.
Has that happened on yours?
Thanks for mentioning this.
I spotted the material covering the zips and on one side the flap was folded over.
But the water was leaking through the seam higher up than where the flap was folded.
And on the other side, the flap was correctly positioned, but still the seam leaked.
As well as some leakage through the zip seams, there is also more leakage through the vertical seams that are slightly further back from the zip seams.
I am reserving final judgement until I can test the bellows in a reasonable downpour without having to use the hosepipe. There is a remote possibility that water from the hosepipe was being driven through the seams.
Meantime I have sent an email to the dealer with photos to register a formal complaint and included notification that rejection of the vehicle may be a possibility.
I am very conflicted on the situation :
On one hand, we love the van and are looking forward to many trips away in it. It is comfortable to travel over long distances in and ticks all the boxes for us. I'm not sure what we could replace it with.
On the other hand, having paid £77k I don't expect VW to be taking us for fools. They knew they had a problem so why didn't they thoroughly test the replacement to make sure it was fit for purpose? There are enough reports from new owners in this thread to convince me that there is still a serious design flaw with the latest version.
Pending further testing and the severity of the leaks, I am wondering if the best thing to do in the short term is to buy a topper for when we know there will be bad weather. Then wait until there is more positive news on a watertight bellows replacement from VW and get that fitted at a later date whilst still under warranty.
If the van wasn't new I would have no hesitation applying a water based seam sealer to the affected seams followed by a coating of Fabsil in an attempt to carry out a DIY fix.
I don't suppose there is much chance that VW would allow a DIY approach whilst honouring the warranty if it didn't work.
