It's highly likely that the valves and piston have touched, as with most modern 16v engines. I'd replace the timing belt, then try turning it over by hand, if that works see if it will start. It is however unlikely to start, so it will then require the cylinder head removing to replace the damaged valves. Check everything in the timing belt area; tensioner, idler, water pump etc, as damage or failure of any of these could have caused the timing belt to break
It is the same with the petrol xantia having a glow plug light but the car isn't diesel,its just a standard feature on the dashboard,
