I am getting misfire indications in my DME report across multiple cylinders (without CELs) in my 2019 Turbo Cayenne in which 30K plugg service was done 5K miles ago.

Nevertheless I wanted to verify the plugs were actually replaced, which based on their condition they appear to have been.

How likely is it that the coils have gone bad in a 35K 2019 Cayenne turbo?

Should I worry about it without a CEL?

What are some of the other likely suspects?

Is there a way to test the coils?
