But they said if I rectified the issue myself, they would calibrate it for 30 minutes of labor... $130. I am NOT paying this fee, and my original dealer, Porsche West Palm will take care of it for free.

@eagle1960 basically gave me the answer; I need to lift the car and ensure the orientation is on the open position...
Shot an email @SupremePower to double confirm so that I do this in one shot.
Hi Mate, did you resolve your problem? I have a GT3 equipped with TFL exhaust, recently checked engine light was on and dealer said it was caused mis position with driver side actuator and flap. I also have an error code P047600. They re do it but engine light comes back at the next day.

Hi @SupremePower , Do you mind DM me your email so I can send you the report, I would be grateful if you can help me out

I had something similar after installing a Soul exhaust, I cleared the faults and they never came back.

My tire shop was doing some other work on the car. I thought the code was for a gas cap that I did not tighten enough. I asked them to read it and clear it. Instead they found that it was a fault code for the exhaust actuator shorted or incorrect signal. This was a week after I had the Soul exhaust installed. After they cleared the fault code it never came back. It has been several months now with no return of the fault code. Exhaust seems to work fine.

thank you for the input Sir.
the dealer cleared the code for me but came back next day then disappeared now. But they said even tho engine light was not on, the faulty was still there. It would come back intermediately. They claimed the exhaust was imperfection welding. The flap wouldn’t fully open since the error code. Overall, it’s a harmless issue.

relearning did nothing. One of the valves was off by a few % which kicked the error.

m-engineering had to code it out for me.

We have had success. Re-learning has worked every time for us on Akra.

@Skychoi42 is coming by soon and we will try to relearn free of charge for him.

Please see this post in the JCR Group Buy thread with an explanation by @JCR-Porsche about what some of us saw with the valves on the JCR exhaust. Seems like this might start being a more common issue if the tolerances of the valve motor "fingers" aren't as strict.

I have the non-valved version of GMG center section and I am getting P04A0 - the opposite side of valve from P0476. What should I do? I am in NorCal Bay Area.
Need to smog the car...

Another possible option is install Cargraphic Valve Controller which masks the exhaust valve DTC and would not be considered a tune.
