How to repair crack on the roof
« på: Torsdag 30. Mai 2019, klokken 20:24 »
I found two cracks on the roof. See attached photos.
I drilled hole to stop the crack (maybe I a bit bigger than it should have been) and am now considering how to repair the cracks. I have come up with 3 options:
 - ABS gluing - there are these ABS sticks and a heatgun at the local Hornbach
 - Marine silicone -
 - Marine 1 component polyurethane -

Ultimately I should remove the roof and re-enforce the panel from the back with a steel grid and then fill it with something... but this is really not something I have time for. So what would be the next best thing?

Am I really only delaying the need for removing the panel and fixing this properly?

You need to fix the crack from inside because it goes under the sun roof. It’s fairly easy to remove the inner liner. I used Tec7 glue and reinforced with somthing i had at hand (dried out wet tissue). Has kept the water out for nearly two years until now.

You should also make a hole in each roof corner, when taking down the inner lining. [ You are not allowed to view attachments ]

How do you take out the inner lining?
I can not seem to find that part in the repair manual.
There seems to be a reference to a screws for the lining in the repair manual.

It’s may not needed to remove the headliner completly. Start in the end where you have the crack.

Thank you for all the advice!
I am attaching some photos.
There are 3 cracks.
It looks like I need to remove some of the rails to be able to get to the whole crack.

I am not so sure how to drill at the corners that do not have cracks without removing the sunroof arrangement - any advice?
Maybe a dremel it instead?
Also one of the crack is under a GPS antenna that is stuck with a black glue and it looks like it will break before it will give... I will try to remove it with a string tomorrow.
