- my CO detector goes off reliably on the ground if I have the door =
slightly cracked.   I'm not sure exactly what is going on but I think it =
has to do with air flowing backwards through the wheel wells into the =
outflow valve.
- if you had an exhaust leak in the cowl AND some leak in the induction =
system (e.g. hoses that lead into the turbos) that would eventually get =
to your cabin pressurized air.
- if you have an engine fire, depending on what fails, you could get CO =
in the cabin pressurized air.

I would take it very seriously, especially since the flow rate through =
the cabin is so much lower than an unpressurized plane that the CO could =
build up.
