I have a lit up CE light on my '07 XK.
When I start my engine holding the Trip computer button I find a faulty PIE in the Module Status.
Does anyone knows what it means?

I sort of found the problem.
PIE got to do with the passanger side mirror, it got stuck facing the curb, like you're driving in reverse.
I couldn't even remote control the mirror. Switching the seat memory solved the problem. Mirror works fine again and the CE light is gone.
