On a side note, are you entirely sure a sensor cannot cause the mechanical failure?
It wouldn't be possible for (theoretically, of coarse) if the sensor is in fact failing or has failed, and the car continues to be driven in this condition; wouldn't the sensor readouts cause the ECU to regulate the mechanical parts improperly, which in turn could cause a failure?
A more familiar comparison for me, would be the thermostat in a home. If the sensor is detecting that it's 80 degrees in a room that is actually a cool 65, the thermostat will still kick on and run at full-blast trying to compensate and change the temp. This happening for several hours or days without monitoring, could cause excessive work to the machine, in turn, mechanical failure.
Is there something in place to prevent the same type of issue in the e92? I'm sure I'm just showing exactly how little I know about our cars, but I'm trying, so please don't bring me down to harsh.
