As above I will start the car when cold the radiator fan runs, it will shut off from time to time but comes back on.

Anyone else have this issue?

I am not sure what to look at. I have read to check for low coolant, air in the system or a bad relay?

 

Chris, the only time I've seen this on a V36 model was when it had aftermarket cooling fans installed. Not saying this is the case, but if you have aftermarket cooling fans I would start there first.
