Thank you for your contribution. The car has already received all the latest updates transmission and engine update. It is quite frustrating. My tuner said it was a blow off error because they would not open. I bought the blow off valves (supplier PIERBURG) a few months ago and recently put spacers on them from Renntech and there valves still look new.
I’m afraid I don’t have the answer here - though perhaps removing the BOVs would be worth a shot?
Also you may have luck searching for a variation of the code you’ve posted in a different format - try P0400 and you’ll see it relates to the EGR.
You might get a better set of codes out of Xentry?
Good Point. There could be a connection.
My mechanic said : Yes, P13C287 indicates that the exhaust damper is stuck, it can cause backpressure and trigger the other error along with the misfire. If you have fixed this error and P00C400 still shows, you need to check the bypass damper 2; the error also indicates that it has a mechanical defect, so it does not move properly. If it is stuck or broken, you will have to replace it.
The P00C400 should be related to the P13C287. But it is not shown in the diagnostics.

Sorry - I don't have much advise specific to your issues, but have you resolved this exhaust flap code?
Have you been able to scan the car with Xentry?
If your mechanic and you are both drawing a blank, is there another specialist you can use to try and resolve the issue? You could try eliminating things like the aftermarket BOVs by removing them and going from there...... if you're stuck then try and boil it down using a process of elimination
I have a 2017 C63 Coupe and I have found the following faults, the so called ByPass valve is not activated and cylinder 6 has a misfire.
Plugs and ignition coils were renewed and the error is still there. What is this error code P00C400? Has anyone had any experience with this?
Any help would be greatly appreciated. In the attachment I have the log data, maybe someone can do something with it.
Best regards

yup I just had to swap this as well I paid $900 for parts and labor which was a rip off but it’s the turbo. I didn’t have time nor did I look it up. But I can tell you mine is a 2019 and just had this done and it ran great until I had to swap the coils plugs and rail sensors at 35k
Oh, what we have here is a catalyst that's had a tour of the underworld. Bought new downpipes with 200 cell cats.
I've decided to reprogram my car's pop and bangs back to the stock settings. It seems that the previous setup was a bit too aggressive for my taste.

Ouch ! Thanks for sharing that pic , hope the new downpipes didn’t sting you to much , is it not an option to run catless in your location ?

I would like to drive without cats, but I'm stationed in Germany as a soldier and I don't know if that's a good idea. I also drive the car every day and I'm worried about the smell of exhaust gases
