Check the exhaust around where it fits to the cat they can leak there if it's not a perfect fit fumes come up under the bonnet and get pulled in to the cab with the fan on when it's cold open the bonnet start the car then look in the engine bay to see if the fumes are coming up you can see the fumes better when the engine cold .

Check for leaks around the injectors, exhaust fumes can blow past the seals.
