When the car is cold it starts first time every time, but once it is up to temperature it struggles and takes at least a few turns of the key.

This sounds like a classic engine coolant temperature sender issue. Once the sensor gets heat soaked it stops working.

Here is a guide to help you see what you are in for when changing the sensor:

Below is the location for your car.

5 - Engine Coolant Temperature (ECT) sensor -G62-.

Please let us know what you find. I'm interested to see what it is.

Cheers, Ken
