A pillar water leak

[NeillyG]

I don't want to redo the entire seal. Do you know where the leak in your roof was located?

I went up on a ladder and looked around the seal. I could see a split up above the passenger door. To be honest filling it with clear silicone stopped the water getting in but the sealant was looking a bit tired and cracked in lots of areas.
I’m still getting water getting in the toilet cassette area but no idea where it’s coming from… possibly from the flush rather than the roof or brake light?

I ordered 3 tubes of Sikaflex 522, and I'll be using them to rework the seals with another fine layer over the existing one, including those around the antenna, roof brake lights, and other areas. I've had a California Westfalia hard-roof for 14 years battling leaks and it is a real pain.

I ordered too a "Black RV Rain Gutter PVC Plastic Drip Irrigation Track" to get the water away from the back doors and perhaps the sides. Will see.

Wieczór wszystkim,
Od miesiąca lub więcej, za każdym razem, gdy padał ulewny deszcz, woda dostaje się do słupków A. Materiał nad plastikiem nasiąka, a woda kapie z uchwytów i wypełnia uchwyty na kubki. W nocy uchwyt na kubki może się zapełnić, jeśli jest naprawdę mokry. Jeśli vany są lekko pochylone na jedną stronę, to problem leży po tej stronie. Oczywiste jest, że woda musi dostawać się wyżej. Czy ktoś jeszcze miał ten problem? Mam nadzieję, że to nie jest trudne do naprawienia. Czekam 9 miesięcy na nowy stopień i zlew. Zaplanowałem wiele podróży, więc nie chcę, żeby van zszedł z drogi, podczas gdy oni próbują go naprawić, ale nie chcę też, żeby w dłuższej perspektywie pojawił się jakiś problem z wodą lub pleśnią.

Hi it seems as the vans age we are all going to have to watch the white seal between the metal and fibreglass raised top. Gabriel suggested Sikaflex522, this might be the factory equivalent.
Does anyone know what the factory product is or what a dealership would use if you went back for this repair under warranty ?
Thanks

I wondered if it was the aerial at the front. No sign of water getting in anywhere further back. I felt up in at the insulation infront of the top shelf and it was either a bit damp or just cold. Other than the step most things have been behaving pretty well for the last year. I still can’t understand why the step is such an issue. I see so many other vans with the same or similar step with no issues. Mine is totally unpredictable. Never fully works but sometimes it puts on a half arsed show for a few days. Usually when you don’t need it then nothing when you do. Is it a software issue? Hoping step 3 will be better but the second only worked for 6 weeks.

Black seals in my case.
I used some aluminium foil tape around the base of the aireal until I re-do with sikaflex and so far so good, but the rain last few days is not that heavy.

My reseal seems to be failing after only 16 months. Water in the cup holder and dripping off the grab handles again. Had a look and seems to be coming away again. Actually if I rub the sealant with my finger a white residue comes off. It was resealed at a body shop VW sent it to so maybe they used the wrong stuff. Pleased to have taken out extended warranty as looks like it will need redone as well. Also been waiting since August last year to get the black vinyl replaced as bubbling, the hob igniter replaced (never worked since hob replaced) and now the truma boiler faults on diesel mode.
In general all works fine but annoying to think that the roof may need re sealed every 18 months. The time it takes VW to get parts and book you in is so far over 5 months. A lot of chasing up required but at least can use the van in the meantime. Shall just add a bit of clear silicone in the gap in the short term.

Anyone had the roof seal redone or done it DIY with longer success?

You need to use sicaflex,

Thanks.
If I can get it done under warranty (which I am hoping I can) then I will ask them to use sicaflex. Not sure what they have used but doesn’t seem to be coping with the climate.

Our sealant joint is going black
I think cutting it out is doable DIY
Do any switched on GC owners know what brand/spec the sealant is?
I have done a couple of local ( possible holes ) repairs with an anti mould bathroom sealant- but aware that was just a temp fix.
Thanks Paul

Lightly sand with medium-grit sandpaper (120–180 grit), then clean with methylated spirits (or acetone) to remove dust, grease, and residue. Let dry fully. The joint may looks big but it is quite thin/shallow, so it won't take much sealant.
