Think you are right @SusiBus posted the letter from VW.
VW's actual wording was,
" As such, repairs are covered by the 3 year paint warranty policy. In an effort to offer our customers peace of mind we took the decision to offer an additional 3 years goodwill, extending the terms of protection from three years to six ".
This makes no reference to any model or expiry date.

We now have the issue of the Warranty regarding to the application of tape under the elevating roof seal which appears to be open-ended.
So where does this leave us, with 3 years, 6 years, or open-ended warranty?

Given that they didn’t specify any model or date, I would think any owner having roof problems with T6 and later would be in a good position to expect the same 6 year cover. On the basis that it was/is a known flaw in the design which VW have acknowledged. What’s good for the T5 should be good for all!
I have a copy of “your“ letter in readiness!

Just a quick word of warning for anyone whose van is due to go off to a VW bodyshop to get the roof repaired....
My van went off in February to have this "2-3 week" job done - and I only got it back just over a week ago :mad:There was only a tiny patch which needed sorting on my roof - I certainly wouldn't have spotted it!

In the four weeks after it was dropped off at the dealers (the perpetually useless Snows in Plymouth), I had endless calls with Snows, VWCS and Marshalls (the VW bodyshop doing the work at Greenham) - just trying to get the work approved. There seems to be a massively over-complicated approval process involving VW and both dealers. This, coupled with Snows' patchy and unreliable information sharing, meant the van was sat for four weeks waiting for work to commence...and you can guess what happened afterwards in late March....

Getting the van back after lockdown was equally painful and involved even more chasing. The dealers need to raise invoices, get them approved, paid, cleared etc - which added over a week to get the van back after work had completed. And the icing on the cake were the 182 unexpected additional miles on the van when returned. Snows' service manager told me he had no explanation for these, that he'd only driven it a mile to fill it with petrol. When confronted with the fact that it's about 182 miles from Plymouth to Greenham, they came clean (via email - I'd driven home by now), and said they'd actually driven it because they couldn't arrange transport. Given the current situation, there's a massive difference between someone driving your van to get it onto the transporter, and someone sitting in it for 4 hours, then purposefully not telling you about it :mad:

So my advice to anyone who needs to pack their van off for this work would be: arrange it directly with a dealer who has a body shop. From talking to Marshalls (who were great, incidentally!) it sounds like most of the delays and bureaucracy can be cut out by only involving one dealership, and they'd have been happy to do this. Oh, and don't bother with Snows for anything.

In that way, you may get your van back in a shorter time than 4 months I waited for mine...

Land Rover never sorted it with the Defender and its predecessors all the way back to the Series 1 first produced in 1948.
Yes they did sort it out. They got rid of the alloy door and rear door skins and fitted steel instead. I had a 2004 Defender for 11 years and had no i metallic corrosion.

I had a 2010 Puma, and it had it. So you were lucky, as I’ve been on my 2014 California.
Front Panel clear, as it should be being a MY2015 and the elevating roof section clear at 5 yrs when the tape was applied.

After 2 years, I took the roof seal off my MY17 ocean and discovered the tape was not applied to the whole circumference of the roof. It took two visits to the dealer to get that sorted. No evidence of corrosion that I could see. I’m glad my seal was not glued on after this, so I can check every year or so.


I just checked my seal last night. Found that front edge of the roof was missing. Which section did you find missing?
I have a 2019 Beach. There are two sections of tape applied to the front cap, where the roof closes down onto.
Just worried that this front edge is likely to see the most movement and is where most corrosion seems to begin!

Hi Mint stuff,

the tape “missing“ on the front lip of the roof is normal, VW do not apply the clear tape to the front edge.

It was one of the long edges. IIRC I was told it’s normal fit it not to be fitted on front edge

I haven't read this thread in its entirety so I'm not sure whether this has been suggested elsewhere already:

( Galvanic Corrosion:
When two different metals or alloys are immersed in a corrosive solution or regularly connected by moisture, each will develop a corrosion potential. If the conditions for galvanic corrosion are present, the more noble metal will become the cathode and the more active metal will become the anode. A measurable current may flow between the anode and the cathode. If this occurs, the anode's rate of corrosion in the service environment will be increased while the cathode's corrosion rate will decrease. The increased corrosion of the anode is called "galvanic corrosion" )

My thinking was that aluminium aka the roof panel and ferrous metal aka the reinforcing strip in the weather seal can coexist happily without the aluminium being corroded but only in a moisture free environment. It is the presence of moisture that creates a situation in which galvanic corrosion occurs the roof panel aluminium being the sacrificial anode in this scenario.

We had our 2012 California repaired in October 2014 under warranty (front section replaced and lifting roof panel repainted). We then moved to France where in April of 2015 I noticed a few tiny bubbles reappearing under the weather strip where it had been repainted but only over an single 5cm section Knowing that dealing with VW Commercial in France was going to be another challenge altogether I decided to pack the weather strip with a good quality clear silicon grease that would be inert to paint and rubber but would keep any moisture out and reduce the chances of more bubbles appearing.

Well I am pleased to say that now after removing the weather seal and and residual grease the very early corrosion is no worse and is confined to the same 5cm area. I have repacked the weather seal with the remainder of the tube of grease and will check again in another 6 to 9 months. I am confident that this is a less than elegant solution to a problem which otherwise won't go away. BTW the front panel thankfully still looks OK.

I was wondering if this worked longer term ?

T6 march 2019, can anyone confirm what tape there should be on the roof edge ?
I just cleaned under the seal and the seal groove, there is tape all round the roof edge apart from the front under the seal area.

I also found a small circular raised "pip" on the edge, looks more like debris under the paint than corrosion.
Any thoughts ?tempImageGj1XXE.jpg

You don't have the side tape that we had fitted to ours.
If this were mine, I would be proactive and purchase some helicopter take and add it myself.

There is tape around the roof edge except for the front. There are two sections of tape where the front corners meet on the body. One bit is coming off, its going to VW for first service next week.

If I had a new T6 and this is a genuine fix I'd find a recommended specialist to do this with PPF (paint protection film) and rest easy. :)

https://www.google.co.uk/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=paint+protection+film

Lots of info on YT about this too and a favourite of the 'supercar' brigade.
Do what with PPF tape please ? I thought from reading the posts above that is what VW have done since Nov 2016 with all T6s... Unfortunately the link didn't work for me

PPF tape between rubber seal and elevating roof to isolate aluminium roof from steel insert in the seal.
Tape factory fitted from Jan 2017 l think.
Dealer recall fit for tape addition. Not sure what vehicles are elegible, but I'm sure someone will post with the relevant details.

Thanks for the info. I just wanted to make sure there wasn't any known or better solution to what VW have done since they started fitting the tape late 2016 / early 2017 - I have a late 2019 Ocean - sounds like there isn't

Apart from a fibre glass roof, that also wouldn't buckle like the aliminium one can!!

Fibre Glass has other problems - check out the Marco Polo Forum. Many roofs being replaced because of blistering. We are NOT alone, as they say.

I am starting this thread so T6 owners and potential T6 owners are made aware that the T6 is subject to roof corrosion.



Here are 3 photos taken underneath the seal on the raising section of the roof on a May 2016 T6 California Beach taken today after our first trip away in her. .

20170108_154624_zpscnceydd4.jpg




20170108_154601_zpsznky53hr.jpg




Our much loved 2014 California SE was unsuccessfully repaired twice, the blistering quickly returned and it was booked in for a 3rd repair. We just could not bring ourselves to go through this all again and we made the difficult decision to part exchange it for the 2016 T6 Beach, thinking the problem had been cured. But obviously not!



So, our 2014 SE has it (three times), a loan 2015 SE had it and now our 2016 has it - the roof issue is still the same.

Remember folks when your warranty is up you're paying for your own repairs.



So yet again, we can either look forward to going to the dealers to register a fourth warranty claim for roof corrosion and then to go on a never ending list for an ineffectual repair but instead we are going to return the vehicle first thing in the morning and demand our money back! (See Consumer Right's Act 2015).



We have also cancelled the new T6 Beach we ordered on the 26th March, 2016 which is yet to be built!!!



Another VW will never darken our driveway again.
I had a 2007 mark polo, it had the same problem,I now have a 2013 california, which I returned under warranty , corrosion problems, very happy with the repairs which cost me nothing

Hi to all,
Yesterday I decided to check on the condition of the so called roof fix that was applied by a dealer three years back.
Not great I’m sorry to say.
As the tape was applied to the outer edge only? I have discovered a small (very small) amount of corrosion at one point on inner side. Strange that it does look like rust(hard to see)
Also in some areas the tape has not quite reached the bottom edge on the outside, other areas the tape has been peeled back (exposing outer painted surface) whilst the rubber seal was Re applied..

I have just about read this whole thread and cringed at the hassle and time lost by many members on here trying to get things put as they should be.

It is my plan now to try and effect a fix myself, so any help suggestions would be much appreciated from those that have chosen a similar root.

My research so far has identified a anti corrosion tape from Heskins (H3453) It’s designed to stop galvanic corrosion. Comes in at just over a tenner for 25mm x 18m+

This is transparent tape and 25mm would enable it to be folded under to do inner side as well.
This would be after I have removed old tape, cleaned, then rubbed down and applied to any corrosive areas an etching primer.
I am not too sure about any form of grease or sealing in the rubber seal after? (As it would be good to be able to check at a later date)

Please if you have attempted anything like this in the past yourself, it would be good to know result, what went right or what went wrong before I start this winter project.
