Thats an interesting snippet in the report, page 58 section 1.16.7 concerning the warning unit taking too much current (how much), it implies that a capacitor wasn't spec'd with a high enough working voltage during manufacture, could a situation arise where the current drawn by the failing capacitor tripped a circuit breaker shutting off other systems (i.e fuel sensor) or the extra current drawn pulled the voltage down allowing false readings, some of the wires can be of a small cross sectional area, drawing a lot of current would easily produce a voltage drop, has anybody taken a look at the wiring diagram to see what other systems are connected to the warning panel supply at the same time...?
Never had a tantalum capacitor pack up due to mechanical stress here on things I make, its always due to over voltage, mainly due to fitting the wrong voltage type...
Just my observation.
