Audi Repair: a4 wont start, good shape, darts

Question
have just got a y reg a4 2.4 se and it sometimes has trouble startin. i have to keep turnin it over til it finally starts.

Answer
There are many reasons why a car does not start, I will need some more information before I can throw some darts at this answer.  Does it happen when it is hot, warm or cold, does the car consume a lot fo fuel, are the ignition wires in good shape, have the plugs been checked?  Let me know,  Jan
