I booked my van in to VW to have it reset and the latest software installed. £300 later it is done.

Well known fault which always appears on French holidays when you’re more than 650 miles from a ferry- all will be well when you get back to Blighty, enjoy the rest of the trip

You might actually be onto something there. This year I've had the yellow "Cat" light on twice, both times I was half way down France, once in January on our way to the Alps, and the second time about 6 weeks ago on our way to Spain. It stayed on for a couple of hundred miles and cleared itself. The fault on both occasions was "NOx reductant bank 1 efficiency" or something similar. I suspect it's a sensor on it's way out.
