Not 100% on this one, but had a similar ish issue on my cdti and was a battery terminal problem. (Terminal broke off when I tried to loosen the batter clip).

Anyway, perhaps worth a check to ensure the 'juice' from the alternator is actually making it to, and through the battery, and not inhibited by crud, corrosion etc.

Hope this, for what it may be worth, helps. Also hope the holiday to that lovely place is also lovely.
