Over the last three months I have started to experience problems starting my leon. This can happen at any time of the day, sometime I can have been out and about and it will suddenly decide to play up other times it won't start in the morning. When I eventually get it going it chucks out loads of black smoke. It may then go a week without any problems. Dealer can't see anything wrong. Any help would be appreciated.

My first guess would be glow plugs. If I remember correctly (i.e. don't quote me) they can be tested by checking the resistance across them.
