To be fair I didn't specifically ask VW if this would be fitted, I just knew that the engine was bio compatible and planned to try some in the future.
Now I am wondering if this system can be easily removed, restoring the ability to use bio?
I suppose removing it would invalidate the warranty. Bugger.

John,
our 2007 VW Caddy 1.9 L TDI engine runs like a dream on Biodiesel.
I have now done 7700 Km on anything up to 100% Biodiesel (from new) without any problems.
The only problem is that Biodiesel has a much higher viscosity then PetroDiesel and will give problems in cold weather. I run a 20% Biodiesel/ 80% Petrodiesl mix in the winter. (temperatures drop to about -5C where I live in SA).
When I start the engine I rum it at about 2000 rpm and wait for about 10 seconds when the engine speeds up and I know I can go without any problems.
I have been trying to find out about what is different with the European "heated" fuel system, as mentioned before in this forum, but have been unable to get information so far.
I would appreciate information, on the heated fuel system, if anyone can help.
