See owner's manual page 218 onwards for instructions. I've got the LED headlights. But judging by the manual, it should be a straightforward job.

Your low beam bulb is a 55 watts H7LL type. High beam is a 55 watts H7 bulb. Any other wattage, regardless of whether it's LED or halogen, may trigger an error and you'd have to recode your car to get rid of it.

There is also the risk of overheating if you use dodgy brands or higher wattage bulbs. And of course, you will need to check your local laws and regulations to see if using cooler colour bulbs is allowed. Bulbs cooler than 5000K, for example, may result in MOT failure here in the UK.
