Hi, selling a 30min used CG VSC-2 Variable Sound Controller for an 2015+ m3 f80, m4 f82, m4 f83. It is a super easy install. Takes around 15 min to install and comes with both remotes. You can also very easily link it to your homelink buttons. I'm selling this because I just realized by jb4 I have has the same ability to open and close anytime I want. This is set up to default to OEM flap control and when you turn it ON it opens the valves. This was an awesome mod and would've kept it if I didn't have a jb4. It's my fault for being so impatient and not doing more research before purchasing the jb4.
