Hi.
I installed an upgraded exhaust on my 2024 GLE 53.
And transferred all the exhaust valve sensors from the oem muffler to the aftermarket one.
But now I am getting a check engine with code P13C2 for actuator flap.

Does anyone have any recommendations? Was it installed incorrectly? Is there a procedure to reset it or any other suggestions would be super helpful

Do the flaps actually open and close when you push the button? If not, I would check the spring in the actuator and make sure nothing is broken there.

Left side works as needed. The right one does not open fully. When the car is off both flaps should be 3/4 open in resting state the right one is closed it its like its trying to reset clicking open a bit and back to close.

I checked on the springs currently nothing is broken.
I really think were doing something wrong and the flap is reading the right position somehow.
