Not good. For my reference do people lift the seal on a regular basis to check for rust i.e. annually? Is rust here a common problem?
Hi GG

I check mine twice a year since new and this is the third instance of rust, all in Different places!

The seals are not fit for purpose and should be checked regularly, interestingly the dealer would rather you left it !

When I pointed out, to the dealer, that this seal is Brand New ( 2 weeks old) and it has failed & if left the result would be a £4K warranty repair and a year long wait for said repair, I was met with Silence!

it’s a fact that VW have designed and continue to fit a part that is not fit for purpose, this site has been banging on about it since God was a Boy.

VW offer a one off repair!
when that fails, as many have (look on the forum) you are on your own or your left to argue with VW’s nominated repair co.
yes the repair compayny VW send you to but don’t warrant their work !
The repair company have no interest in doing another repair (the details of which are probably specified by VW) for free, particularly as the original job probably didn’t pay too well either !

VW knowing this, simply stick a bit of tape on three sides of the roof to slow down the process (Probably reduce the incidence of in warranty claims enough to justify VW doing nothing about the wider Known issue)
If your roof seal fails (becomes rusty) the chances of your roof getting the dreaded corrosion are very high if left for a period of time.

The front of the roof is at risk as much as the sides, two failures of seals along the front section have proved that.

Check and clean you roof edge and roof seal regularly, treat it as part of your maintenance regime.

Thanks @Perfectos will check mine on the next dry day. Is a smear of Waxoil or similar a worthwile precaution?

I can’t see that adding anything will effectively stop the rust particles from touching your roof, once the rust forms it’s able to penetrate the paint and react with the Aluminium which then corrodes and bubbles the paintwork and so the process goes on !
the method adopted by VW, create an impermeable barrier, appears to be the most reliable long term but does rely on you noticing when the seal fails and the rust form , then change the roof seal ASAP warranty of £75 per pop if out of warranty!

Today, I received a set of air vents for front windows. really look the part and I think they are much better than wind deflectors.05169B25-DF0B-4061-A98E-ED4C6BCCD3AC.jpeg

... and I think they are much better than wind deflectors.

Different use-cases:
  • you cannot have these fitted when in slow/stopped traffic and rain, you want to roll down your windows without the rain coming in.
  • deflectors are fit and forget and they stay on.
  • when at a site, these are good, but as mentioned, a faff to fit on.
  • you have to take them on and off when needed and also find place to store them when not in use.

Could you have both on, I mean you could take them of when driving and just leave on the wind deflectors

Do you think that part of the problem is people inspecting the seals?
If the seal has a thin coating of rubber over the central steel clip, surely pulling it on & off is more likely to expose the steel which will then rust.
The tape put on the edge of the roof should stop any rust coming into direct contact with the paintwork as it forms a physical barrier, unless of course the steel clip has scratched through the tape as a result of it being pulled on & off.
If I was pulling the seal off once a year to inspect, I would be thinking about a new seal every time as a precaution.

Good point @andyinluton but I guess the answer might be whether ONLY those who have removed and refitted the seal have been affected by corrosion?

Inspecting the seal should not cause an issue, the first time I inspected the factory fitted seal it was rusty !
the replacement seal was than found to be rusty after the second inspection
the third seal rusted after two weeks and was visible from the outside !
the amount of rust experienced will simply rise above the tape through natural process

the seal is not a water tight seal against the roof panel, Have you ever looked under a roof seal ?
the answer is there is a lot of crud and water accumulates in the recess, providing an ideal environment for rust to form on a faulty part

I don’t think merely pulling the rubber seal back in two foot sections twice a year causes the issue, I think VW provide sh ite seals that are known to cause a severe issue with their product and are unwilling to fix a problem they created & know fully the consequences (4K repair and a two year wait with no guarantee to fix the problem)

look at the rust carefully, this is after two weeks, the seal has failed on the out side and inside. Had I not requested tape to be applied to the front lip, the rust would be in contact with the roof panel, and bi metal corrosion will start very soon after. the tape is a sticking plaster (literally) it is not applied to the whole roof, you can see from the photo the rust will track along the rubber seal and as it grows it will breach the tape (where it is applied)

this is a case of poor product not fit for purpose.

why are the dealers told by VW via a work shop bulletin, to remove the seal and inspect for corrosion if the action of removing the seal damages the seal seal to the extent the problem would occur ?

7F35D3A9-2780-4089-B748-59AD50D68BBB.jpeg

The applicable Workshop action is 75A1 states that if the roof frame seal has damage such as corrosion or cracks then it should be replaced. Even if your vehicle is not due the workshop action and the seal has corrosion then it is a warrantable item and should therefore be replaced.

Those vans that have had The roof seal fail will never know it has failed until either it is visible outside the rubber or the roof corrodes !

I’ll keep checking the item that is known to be an issue, particularly as I have first hand experience of a new seal rusting within two weeks of it being fitted !

Checked mine today @Perfectos . The van is one year old and there was lots of crud (and some water) under the seal which I cleaned off but no sign of rust. I noted that mine already had clear protective tape wrapped around the roof edge as fitted in the factory. Still wondering whether a light spray of light Waxoil might be a good precautionary treatment?

Glad to hear your seal is all good
I cannot advise re wax oil, only to say that VW have not come up with a solution despite this problem having been present on all models to date from the T5

some reading 4300+ posts regarding a whole host of issues directly related to the roof seal failing !

Installed the Calitop Cupboard shelves in the hanging closet. This should be a Cali-option or even come as standard..View attachment 86871
I can see why plenty like them, but I would miss the hanging space. For us it's packing cubes in the rear cupboard and the wardrobe for hanging jackets. The space at the bottom for a dry sack for dirty laundry. But each to their own and these certainly look nice. Option? Maybe. Standard would be a disappointment for us.
