Thanks everyone for your input. My reply ...
Dear Mr Myers
I am confused by the contradictions in your emails…
In your first email you advised that the cam belt life is set by the VW factory …"The factory have set this as a recommendation just like they set the recommendation for every market that they make vehicles for."
Yet in your follow up email you admit it is a VWUK importer decision … “The decision to include a time as well as mileage is one taken by each importer. The specific reasons that lead to the decision, which has been implemented throughout 2 generations of Transporter are not available to share however they include average driving conditions, traffic levels, environmental factors, and indeed whole life vehicle maintenance costs. As it is only a recommendation, it is at the customer’s discretion if they choose to service the belt at our recommended intervals and does not impact either the vehicle warranty, which is for 3 years, or the warranty on the belt, which is 2 years."
I would like to seek clarity as to why UK owners of T5 & T6 Transporters (including my California) are being prompted to pay for an unnecessary procedure. From reading various VW Transporter forums, it seems that VW owners in Europe have a good history with trusting that the inspections of the cam belt at every service are actually taking place, i.e. there has been no rash of belt failures in Europe with the 210,000km limit, because a problem can be detected if there is early wear. Can you please advise if UK owners can be confident that their cam belts are being inspected by the VW centres, and that accurate information is given if they "choose" to not follow the UK specific recommendation? Is it a case that in the UK VW dealerships are not inspecting the cam-belt. If not why not?
I also challenge that the warranty on a new vehicle is for three years, but the warranty on the belt is only for two years, but we as owners are "recommended" to change it at four years… but only in the UK and not in Germany, Belgium, France, Spain, etc. This would only make sense if UK vans were fitted with belts manufactured to a lower standard than Europe. Is the UK cam belt a different specification to elsewhere in Europe? If I had a cam belt changed in France, would this then mean that I would only need to follow the 210,000 km guidelines?
I look forward to your reply and confirmation that you will be raising these queries via 'Technical Reporting via the Van Centre Network’, because as a customer, I do not have access to this reporting channel. We are directed via VW Centres to raise any general queries with your department at VWCC. Thank you.
Sincerely,
