What are these codes?? Help!

Got a CEL on my '19 C63s yesterday and it's become undriveable.

Was running map 2 for the past few months with no issues until this.

Can anyone tell me what the issue is?

Thanks in advance

Without a description, I'm not sure.

Have you cleared them to see if they return? could have been a fluke.

After scanning the car for faults, my mechanic and I determined the cause is this was from the JB4. After removing it, the car stopped misfiring and the CEL was gone.

Odd...I'd recommend reaching out to [email protected] for individual technical support on it.

When emailing in also let us know how it was installed. The old way had 4x MAP sensor connections, while the new style only uses 2x MAP sensor connections.
