Agree with car nut (which seems to be rare) that it it's too early to draw conclusions. Guess that the big red alert lights are on in Zuffenhausen

Not sure if one should feel flattered.  

If one looks at the photograph of the blacken hulk posted below, one will note that the fire department removed the wallboard trying to identify the potential origins of the fire.  One will also note that in the upper righthand corner, the wall is heavily coated with soot.  This is probably where the charger was installed.  Therefore, leaning more heavily toward a charger or wiring issue rather than the Porsche being the source.
