so i was thinking for future reference...i know some cars have a fuel pump inertia switch that will get triggered if your in a collision and that shuts off the fuel pump for fire safety purposes, do our cars have one? if so wheres it located, this might be usefull if your in a accident and it gets tripped and you need to drive your car off the side of the road

I believe all injected cars have to have one. It should be somewhere under the dash, or somewhere in the trunk.

^^x2. i only know of fords having this.

we do have fuel cut-off valves in case of rollovers though. the old a6's and allroads actually have to have them reinforced (a warranty repair regardless of mileage aka free) at the dealer.

B5's don't have a fuel pump inertia cut-off switch, at least not Euro versions.

Sometimes that sort of fail safe is connected to the airbag controller. If the airbags go off the fuel pump power is cut. I don't know how it is dealt with in these cars.
