Wasn’t there was some chat above about new bellows (potentially not the C) as well as a version in Germany with taped seams? Although none of it is very clear nor convincing.
The manual roof has original version 'B' and variant 'E'.
The Ocean original version didn't have a letter and the newer variant is 'C'.
I think the 'C' and 'E' versions were in production late June and into July. That's the date on the little white QC tag.
I believe also that the 'C' and 'E' versions had some kind of seam sealer tape on them.
Where this get's interesting is VWCV (UK) Customer care were saying last week "There's a completely new version available". Now, I'm unsure if VWCV (UK) are in catch-up mode and think the 'C' version is watertight, new and our saviour or whether there's actually a newer version of 'C' which maybe has some different seam sealers or additional QC etc but has not had the version revised.
My dealer told me good news after pulling the bellows apart, "There's a new product code out there with a 'C' in it". Now they clearly weren't aware that 'C' has been around since early July or they would have known this. I suspect also I'm their first bellows replacement.
The only other bit of news I can glean is that these products have been unavailable to order for a number of weeks - I'm guessing but I think from circa mid-August they went un-available. So far as I can tell they have only just got back into stock for delivery in October.
Maybe that's good news in they've been working on a watertight version for a month or more but it then begs the question, what is the pedigree of the bellows installed during August and September??
