"Just a fair warning, my coworker was working on an i3 two days ago. The vehicle had the vapor line replaced due to a recall, before it was given to him . He literally opened up the rear of the vehicle to check the oil and it ignited, burning him badly. Second degree burns on arms, legs, hands, and face . Vehicle finally went out after 5 extinguishers. If you notice smoke or smell something sweet contact your dealer"
Details are still pending... I assume you could smell the gas vapors if it has the concentration to ignite? What could ignite it?
