Cracked sunroof surround

[CookieMonsterGTi]

When I spoke to VW they said there was no special fix, just like for like replacement on the affected parts effectively.

Does provide much hope, especially when you hear of it failing for people a second time!

I would expect it to be covered by basic consumer rights (fit for purpose) post 3 years warranty period to some degree, but of course there would be no guarantee on that.

I am also interested to hear if anyone knows anything special being done as part of the fix to stop it happening again?

*Mine is currently awaiting repair.

Have a look at my post number 114 on page 12, that may help.

Thanks. I looked at that but for the life of me I cant see the difference between the pictures

From memory the original seal seemed higher up so I wondered if it wasn't allowing enough room for movement/expansion. The new one seems to sit below the panel and less visible. I may have imagined the difference but I noticed it the first time I looked at the replacement and the dealer did say they were being fitted wrong at the factory, how true that was though I can't say.

Mine is now booked in for Next week.

On a positive note they did the same job only a couple of weeks ago so know exactly what needs to be done and how.

The flip side is they said it was a nightmare of a job as its bonded in place and requires cutting out (as mentioned earlier in the thread.  Dreading it to be honest...

Great that it is booked in. I know it's difficult not to be concerned but it'll be fine.

I keep checking mine after reading all this as we have same TCR

It is a bit of a worry but I must say I really like having a sunroof.

At least VW are, at last, recognising it as a fault and replacing them under warranty.  A technical bulletin was issued to dealerships in February apparently.

Any ideas on what it said?

On a side note my booking may get pushed out as the parts are now on back order from Germany.

Seems like there may be quite a few with the issue maybe...

^^Something to do with the incorrect way the bonding adhesive has been applied, which is causing stress at the point where the cracks appear.

Edit.  With thanks to Mark Burgess on the MK7 facebook page:

"VW acknowledge this is a problem and will change the surround, as a bulletin was circulated by VW on 19th February 2021.
The problem has been the way the sealant has been applied, not fully constraining the surround, so with vibration, road shocks, torsion of chassis and thermal expansion the crack forms.
When it been replaced with the VW stated sealant will fully constrain any movement in the surrounding metalwork will be absorbed in the sealant, therefore distributing any stresses and strains evenly, therefore not forcing any cracks.
This is not down to 19" wheels, uneven jacking or hard acceleration, just sealant issue
Problem solved and now accepted by VW."

Thanks for that, appreciate it.

The guy who did one a couple of weeks back mentioned a lack of sealant near the corners but thought nothing of it. Maybe this was what he was referring to.

Either way it’s good it’s acknowledged by VW.
