X5 Wrecked - got some questions

[jek889]

My wife was driving our '04 X5 4.4 two weeks ago and was rear ended by a young woman who had no valid license and, of course, no insurance (got to love SoCal!). She did have a cell phone though and she was probably talking on it when she hit our X (figures). Anyways, the damage sounds exactly like yours...dented lower tailgate, crushed bumper, broken tail light, bent mufflers. Yes, the power cut-off kicked in and my wife couldn't start the engine either. AAA took it away on a flat bed (I always told my wife to ask for a flat bed to risk the least amount of towing damage). We should have ours back next week, and I'm taking it to the dealer to have it checked out afterwards, just in case, to make sure all the electronics, etc. are OK. At least the X did what it was supposed to do and no one was hurt. I told her that she needed the extra safety features of the BMW, and now she really believes me! Good luck w/your repairs.

I was in a similar accident about 6 months ago. My pass and i walked away without a scratch. The X5 is amazing at its ability to prtect its passengers. Im glad your family is ok. and yes my X5 shut off too. It is the BST (Battery safety terminal) that severs itself by using an inertia switch to trigger a tiny explosion of sorts to cut the cable in 2. That cable goes from the battery to the fuel pump only. That what i was told by my dealer.
AQs far as exhaust if your gonna change it go with the 4.6is and get the rear under bumper diffuser whiler your at it. Its like 150 bucks.
