Hi Joey,
I have the same model of car but fortunately I havent had to change a bulb yet. But lets see if we can help. There is access at the top of the light too but you need fingers like ET to do anything in there. The hatch in the wheel well of mine gives much better access from what I recall. I dont think its actually a bumper off job to change a bulb on these, most cars with access issues usually make the headlight removable but I dont think BMW did that option in this case. Id have a look in the wheel well first.
If you go on realoem.com and use your last seven digits of your vin you can find out loads about your specific model, including your lights set up.
