i guess that gunk is maybe a mixture of the oil what is inside the coil and something that is melted ?

Top right shows a fairly hefty in line fuse connected with heavy wire-certainly not OE I would say.

Coils are basically filled with oil to cool them.
 I can't see the fuse gizmo?
If this coil exploded under the described circumstances..trundling along the road in Paris...it is only the 2nd occurrence of that type I'veever  heard of. ...irrespective of make/model.  :o

Maybe also just an example of how crappy quality has become nowadays.  Bosch used to be rock solid quality but even they seem to have fallen by the wayside :'(

Same thing happened in the 350 I've parted out. Somehow the coil windings got shorted and it caught fire then popped. At least that's what the previous owner told me as it happened under his ownership.
