But wait. It is in my guide, which surely means that it has nothing to do with a function that is not available on my vehicle.
I also found the following statements: "
Drive the vehicle for a sufficient
length of time to recharge the additional battery" and "pull off as soon possible". I won't provide reference because I do not want to deprive anyone the opportunity of accusing of lying and you can make of these what you will.
Strangely, I couldn't find a warning not to drive with the tailgate open, something from first hand experience I am very surprised that, by omissions, VW have recommended, (edit - sorry, my mistake, it comes under "boot lid". Weird that no audible warning is provided if left open though).
There are numerous omissions that I'm sure others might have fun suggesting you try.
Finally there is a recent thread elsewhere that suggests that if close to full and the DPF is deprived of a regeneration, (through idling), it could force the engine into limp mode. This is something that can only be rectified at great expense and not something one would want in a muddy field at Worthy Farm. I have no idea if the person saying this knows his stuff, but I guess he must be mistaken.as VW don't appear to have mention it in the manual.
