Question
Petrol C4 doesn't start or takes a lot of starting?

Answer
Car struggling to start, when left a day or so in cold (or any) weather, turns over fine, it seems like the spark plugs are not firing.

Does go in the end though

Sounds like coolant temperature sensor faulty. It'll be sending the incorrect information to the engine ecu, making it think it's colder than it is - basically causing it to overfuel and flooding the engine.

Try unplugging the coolant temp sensor - (green sensor to the right of the cylinder head)... then try starting which should eliminate the error temporarily
