Leaking oil means old car because gaskets fail. You did read the first recall right? Actually, you did but did not internalize any of the relevant facts presented. Oil onto exhaust manifold=fire. But your conclusion is "gas tank fire".
The second...well, Bimmer's being full corporate garbage by simply not investigating. But because THE ENGINE WAS OFF, the more probable pathway is wiring/electrical. Once again, that's not the gas system igniting.
Because
Action of
"oil onto Manifold"
is not even relevant to
gallons of gas stored in the back.
Nor is action of
"electrical fault like a short" somewhere
relevant to the gas tank, initially. Might have made the fire sustain itself in addition to the plastics in the car, but it wasn't the root case.
Bimmers blowing up could negligent wiring issue, which also can be
What I don't expect is "new" or just broken in car to
So for cross examination,
1. do you think new gas ICEs are giant fire hazards? and
2. smoke dectector are inadequate for garage parked gas ICE's?
3. Said smoke detector codes have been that deficient for decades?
