Here's the Fisher Outdoor (UK importers) / Look info notice
http://www.fisheroutdoor.co.uk/direct/images/keo_recall.pdf
Tells you how to identify if your pedals are affected and what to do -
"Bring them to your nearest authorized LOOK dealer, where the axles will be upgraded free of charge."
Fisher Outdoor's site
http://www.fisheroutdoor.co.uk/public/index.php
also has (top left) a 'find your retailer', so enter your postcode, find your local one who does Look and go and badger them.
I've just rung my local dealers, Ron Spencer of Warrington, been told they know nothing about it, that there's no problem at all with the pedals, but if there were they would demand to see proof-of-purchase saying that I'd bought them from there, otherwise they wouldn't undertake any warranty work.
Very useful - but then that's why I stopped going to Ron Spencer's...
