C63s power loss/ valves

Hi, I have a C63s that has power loss. The car gave me 3 codes: P13C700, The exhaust flap has an open circuit or other electrical faults. P140473, Exhaust flap 2 is faulty, does not open. P140471, Exhaust flap 2 is faulty. The actuator is blocked. I tried installing Mrt Proformance valve simulators after to maybe clear the codes, which it did for the 2 codes: P140473, Exhaust flap 2 is faulty, does not open. P140471, Exhaust flap 2 is faulty. The actuator is blocked. But my car is still throwing code for P13C700, The exhaust flap has an open circuit or other electrical faults. and has power loss. Has anyone experienced this and maybe knows a way to fix it?
Thank you

Check that the mechanism goes freely.
replace actuator if he is defect.
with U78 you have 3 flaps.

@userr177 the third valve is at the H-pipe section of the exhaust, in the middle of the car below the back of the transmission.
