Full “recalls” are only ever undertaken, in conjunction with and direction of VOSA, for faults that are deemed by VOSA to cause the vehicle to be unsafe to drive. Anything else, either design or manufacture, is at the “discretion” of the importer, distributor and franchised dealer network to sort out. Often via service recommendations. Always non-compulsory. Hence why solutions can differ from dealer to dealer.

The dieselgate software fix was odd, in that it was a bit of hybrid. A non-compulsory VW/Skoda dealer “Service Action” that had some input from VOSA. VOSA’s only involvement however was to mail out the letters inviting owners to take their cars to a dealer. On VOSA headed paper. All paid for by VW (I was told).

Regular Service Actions whatever the cause, don’t normally get recorded on things like HPI checks either. Only full safety recalls.

Personally I think the pano roof is too large and has reduced the rigidity of the roof allowing it to flex. Then over a period of time and flexing things start to fail.

Coupled with the sealing between the pano roof’s frame and the opening in the bodyshell’s metal roof panel - going brittle over time and failing. That some more recent respondents and posts have pointed to. Then my guess is the two factors together combine to form perhaps 80% of the problems for those owners who’s cars have developed the issue.

Maybe half of the other 20% being cracks in the plastic areas of the roof frame itself? Related to to the same flexing and “plastic fatigue” (growing more brittle) over time.

With the final chunk comprising those cars with drain tubes issues that were identified by dealers while cars were still under warranty.
