Hi all,
Don't want to alarm anyone unnecessarily but a word of warning ref. alternator belt - mine shredded itself on Monday which left me stranded on the M6 for 3+ hours (but thats another story). Eventually got to Research & apparently other Punto owners have experienced the same (same alt. unit).
Suspision is pointing to frozen alternators, which free up on starting but the damage is done to the belt. By my experience you have max. 15 miles before your battery runs out of juice (not nice in this weather).
My advice is to ensure in this weather that if you clear snow/ice from your windscreen that you run the car long enough to dry any draining water that reaches though to the engine bay, otherwise it will re-freeze. Also watch out for any slow cranks, could be a sign - I took it to just be the cold acting on the battery charge.
