Removing fenders on the BMW 335i (or any E92) is more difficult than I would expect. The main reason is because some of the bolts are just very difficult to get to. Some of them are in the wheel well, some are inside the fender and some are behind the side skirt. In this video I show you how to access all of those bolts and remove the fender. The passenger side has an additional step as it requires the washer fluid bottle to be removed as well.
After installing the wireless CarPlay on my BMW 335i, the only thing that was missing was the reverse camera. Fortunately, this was a very easy add on thanks to the add-on I had already installed in the camera. This $35 dollar camera functions as you would expect and has great quality for the price. Install took me about 90 minutes total and it’s definitely worth it to make the car a lot more modern. Hope it helps you install yours as well!
