2015 M4 exhaust valves loose HELP
hey guys just got a marina blue 2015 M4
The inner exhaust valves are stuck closed no matter what I do. They flap and rattle when the car is cold, and sounds TERRRIBLE Any advise?? Thanks!

If you remove the exhaust actuator (3x 10mm bolts) there's a spring clip underneath. It looks like half a paper clip. Bend it open a tiny bit more so when you reinstall it pushes down more on the exhaust flap post. This reduces valve flap rattle.

I still cannot get my exhuats valves to open up. Anyone have any tricks for this? I just want to open them, and leave them open at this point. THANKS

Did you remove the actuators and see if the flaps turn at all?
