BMW M3 Forum (E90 E92) - View Single Post - Replacing Brake Vacuum pump due to code 27e4

Can I replace the brake vaccum pump on a e92 M3 by detaching and removing the front left fender liner? And if I replace the vacuum pump, do I have to flush the brake fluid?

Unless it is completely necessary I don't want to remove the master brake cylinder to replace the vacuum pump since it is a longer heftier process.

Would you guys recommend buying it used or new?
