Hi, ive got a corsa c 2002 sxi, my son damaged the front of the car, bonnet slam panel bumper etc ... both air bags were deployed. ive replaced the dash inc airbags, but ive noticed a small bump under the carpet behind passenger seat, is this a crumple zone ? ive managed to straighten it out, but a little concerned it may well be a crumple zone. before i spend any more money on it, could u advise pls. thanks Rob
