I just checked the roof seal for the first time on my MY17 Ocean (delivered March 2017), which I have owned from new. I can't see any corrosion and after wiping with a damp cloth, the roof looks clean. I noticed two things though.
Firstly there is a sort of whiteness under the tape in places, which looks suspiciously like water trapped between the tape and the roof. Is this normal?
Secondly, the tape does not extend all the way round the roof. It runs all along the (UK) passenger side from the front corner around the rear corner, across the back and then forwards about a third of the way along the (UK) drivers door side. This means there is none at the front edge at all, and a large section of one side has none. The end of the tape is not "clean" and I guess either it has been partially peeled off by someone (not me), or was never fitted (eg the tape ran out whilst being fitted to the roof). Either way, I presume this is a fault.
My questions are:
1. I recently had the van serviced at a dealer and I know there is a recall to check for roof corrosion . Would they have checked the roof without asking telling me (because it is a recall)? I don't even know whether my vehicle was included in the recall (I assumed not, as I knew it had tape on the roof edge)
2. I would think it ought to have tape on it. If I go to a dealer, would they apply tape but then be obliged to glue it on (as I understand that this is required as part of the fix)? If that was the case, I think I would choose to obtain some of the tape and apply it myself, as I would like to be able to remove the seal periodically to check for corrosion.
