A 1.2 Polo, starts on the button from cold. After stopping when warm there is a 50/50 chance it won't want to start again. Turns over for ages and ages without firing, after many tries it will fire/misfire, finally pick up and then run as normal. Cat warning light has now come on, suspect this is related. Sounds like a fuel problem to me, sounds familiar and if so what's the cure?

The cat warning light came on because of all the unburnt cranking fuel saturating it.

Check your spark plugs and coils etc and get it on a diagnostic machine for good measure.

not exactly sure if the polo management is the same as golf but a hot starting problem can be down to the temperature sender/cold start valve/thermotime switch. if it thinks its still cold once the car is warm then the ECU will be chucking far too much fuel in.
