Thank you for that, I'll contact GFB direct and see what happens. When/if I get the stronger spring I will give it another attempt and feedback my findings. :happy2:

I thought I would add a response straight from the horses mouth. I have been in contact with the guys at GFB for a few weeks now and asked about the recent situation. Here is some of the response;
----
It appears that the factory remote diverter valve mounting block runs a larger diameter inlet bore than the turbocharger compressor mounted models. This is a concern as it actually plays a huge part in the valve area ratio of the forces acting on the DV+ piston. Although it is not a problem on all of these vehicles, this is still not acceptable. We have seen factory mounting block diameters ranging anywhere from 18.8mm to 19.7mm, so there clearly is a tolerance issue on the factory part which we must work with. Essentially, what is happening in the practice is these remote mounted units are only just partially trying to open the DV+ piston due to the incorrect piston/face area ratio. This is only with higher than stock boost levels. Still not acceptable.
Our solution: We have nearly completed an almost identical design DV+, but using a larger piston diameter. This will completely eliminate any issues, and ensure 100% fitment on every vehicle remote mounted diverter valve. These New DV+ replacements are approximately two weeks from being available. The current DV+ will continue production unchanged for all VAG vehicles fitted with direct turbocharger mounted diverter valves.

That was a week ago now so they may have adapted this further. The engineer there seems a pretty switched on guy so confident they will get on top of it pretty soon.
My DV+ arrived in the post the other day and will be fitting it on the weekeend :party:

This looks like a good product, it must be a bit embarrassing for them that the R&D is being done after its hit the market though. The price isn't going to break the bank but does seem quite steep when you look at what's included in the kit.
Its not like they can blame the price on "Product Development" like APR do.
