Anyone know if the little plastic bit that surrounds the door lock button is a) available as a spare part and easy to fit? Its the one with the LED in to indicate deadlocks activated, etc

I think this is what you're looking for http://www.skodaparts.com/product/fabia-locking-knob-guide-with-led-2000-2004-36979

That's it, I broke one too, it's always best to prise it out where the LED is, the plastic is much stronger at that point.
