T6 Cali On Order
Yes, I would fix that myself. Just save the inconvenience of being without my van for a day+.

Oh really? How would, say a DIY averse (read incapable) chap, go about that?
All the best
You can purchase the 3M "Bicycle Tape" from Viking Tapes. Wait until the warm weather return.. pull off the seal from the edge of the front cover, remove the old tape, clean up with isopropyl or similar them apply the new tape and replace the seal..

After 18 months of trouble free ownership I noticed this last week. Worth checking yours if you have the protective strip installed from the factory which I think is most T6’s. It’s in with Tonbridge (who have been excellent generally) for warrantee repair. They have advised that it needs to be sent to a body shop. Does anyone know which body shop in the south east has the best reputation for fixing roof issues?

Ditto same thing has happened to our Cali . Sticking out on the passenger side.
Looks identical to Aca-chap photo.

Dont think our 2016 Cali had the protective tape . This appears to be under the front panel Still not sure we have the protective strip under the elevating roof trim.

Can’t find the 3M bicycle tape on Viking tapes. Must have sold out.

Husband will do a self fix. Thanks Loz.

Finally able to get roof and have a look at the tape sticking out.

The tape is 12 mm wide. Can only find 3M tape 25 mm,so will need to use a craft knife to cut it to size. Not much needed.
Husband happy to do this as per Loz instruction rather than let a body shop mess with the roof.

Why cut it down, just fold it under. It might sat put if you do as the seal will hold the back edge on.

Thanks Stoneybroke on no. 3 That final sentence is a cause for concern - is there an expected time that a vehicle is expected to last then do you think?

Anyone able to chime in on no.s 1 & 2?

Hi Everyone,
On hearing of the recall recently announced on the roof issues, I booked my two and a half year old Cali in to be checked and have tape applied if no signs of corrosion.
Low and behold.. a couple of spots were found so booked back in for repair. I was told it’s a local touch up if corrosion can be dealt with below the seal line. If not it’s a specialist job???
I have now been told that it is possible that mine is possibly ok for a local fix and is now booked back in.
Over the weekend I completely removed the rubber seal and checked to found several tiny bubbles starting all around the roof. Not just outside of roof but a couple of places inside. All within an inch of edge I think.

It raises more questions with me now.....
The tape is that, just tape... there are areas not showing any symptoms of the fault but being a design or production fault.. the fault still lies beneath, it may be delayed a bit now with tape.. but still there to break thru as and when, maybe 5 years down the line.

I am no metallurgist or out like that but when you use electronics to apply paints you create charges to attract the paint powders. Introduce alloys with steal and you have now built one dirty grate confused capacitor that may not be too happy with its new coat...

Something like that anyway...

I will keep all posted as it goes on.....

Prospect of 'local touch up repair' sounds alarming as alloy corrosion needs to be cleaned/neutralised and an etch primer applied prior to to top coat application for a complete cure.

As far as I am aware most problems are with the elevating roof not the main van body or cab cap section, if you add the 3M tape yourself it has to cover the inside and outside of the elevating roof edge.

Just read back on this thread and see this is a separate issue, just ignore this.

Hi Everyone,
Just had recall done on my roof. Very pleased with results at first sight.
I was shown the tape and the process explained to me before work was carried out.
The tape was manufactured by ‘Tesa’ it was Vw bagged but looked like a small half inch in width.
After the small blisters that had been found near the edge had been dealt with the tape was then fitted and rubber seal replaced.
All in all a very neat job done locally.
The tape pertudes above the rubber but really is neat and is difficult to see. All completed in just a couple of hours or so.
I did notice in the tape kit two shaped pieces of tape which were obviously for two round corners at rear.

I was a little apprehensive as to what it would look like on completion. But after chatting with the technician first and then seeing the results I realise my concerns were unfounded.
The technician really did do a great job in apply the kit.

How good is this solution?... only time will tell I guess.
On my return home it hammered it down with rain and the rubber seal had taken a lot of water and to my eyes it has nowhere to go?.. (unless roof left open for gravity to help).

I will now write to Vw and ask where I stand regards warranty for this repair.

I see this as solution for the symptoms caused rather than a solution to the manufacturing or deign fault.

Fingers crossed.....

My suspicion is not eating at me and as I am one of the "don't look" until nearly 3 years has passed I will not confirm or otherwise that suspicion.
My T6 was the same build date as your,s They have told me when I collected from my 20.000 service that it has to be in for new tape to be fitted as it is a recall job. they need it for 24hr for the adhesive to cure

Hi, I'm thinking of buying a secondhand camper, is this corrosion problem only on VW's conversion, Is it the case with third party conversions?
I also have the Cambee conversion on my radar would this still be a problem/

The converters all use GRP, that material is invariable quite thin to keep the weight down so can suffer from cracking/delamination and other faults, you pays your money etc.

VW may have this cosmetic Galvanic corrosion but at least the seats and roof etc: are properly tested and engineered for safety even in major rollover crashes - as has been shown by at least 1 Forum member.

I’m aware that there are seats not crash tested and aware there ones that have been, not sure about roofs, I’ll look into that.

Hi Shadrack.

My March 2016 Ocean goes in for MOT in Feb and will have the roof check carried out. I know there's a few bubbles and so keen to understand more about the 'repair' that was done seemingly quite quickly to your van versus the 'take away to a body shop option' - VW seem to be treating the 'quick fix' and the 'full repair' as differently in terms of warranty.

Se below the response I received from VW (I have the extended 5 year warranty on my van)

Dear Sir

I appreciate you have some concerns regarding roof corrosion for your Volkswagen California.

This repair is covered by each vehicle’s three-year paintwork protection warranty, to which the factory has added three years of goodwill. It is not possible to extend this goodwill beyond a vehicle’s sixth year.

If you see any signs of corrosion, we would recommend having your vehicle checked as soon as possible to ensure the repair can be organised in an efficient and timely manner. However, you can have the vehicle checked at any point for corrosion within the first 6 years of the vehicle being registered.

If corrosion is found and repaired, the repair will be covered for three years, regardless of your remaining manufacturer’s warranty period.

The tape method is a recall and would not be considered a repair so will only be covered until the end of your manufacturer’s warranty, which is 5 years in your case.


Did you receive anything back from VW from your letter?

Many thanks
