My car is in limiting the power because my exhaust flaps are sticking I dropped the back of the exhaust and cleaned it good and the actuator are working fine but the code is still coming up also when I shut the car off the exhaust flap is making a clicking sound. If I go to a tuner and code the exhaust flaps out and bolt them open will this fix the problem? it’s a 2019 e63s

 

Crank the flaps open manual and tune them open or out entirely. It works.
