I'm having problems and was wondering if anyone had advice.
I was driving my '06 S55 and it started doing some weird clicking and flashing interior lights, gauges, etc. When i parked it and turned it off, it wouldn't restart (just clicked and flashed interior lights and gauges again). I let it sit for a couple of weeks because i was too busy to deal with it. Over the last couple of weeks the front end has lowered pretty dramatically (back end is fine). I finally got around to trying to get it running today and it wouldn't start. Used one of those big battery jump-starters/charges but no luck. When hooked up to the charger all the electronics worked fine but as soon as i would try cranking it, i would just hear clicking then all the electronics would shut down. Could this be as simple as a battery gone bad or do i have more significant problems? I'm under warranty but towing it will be a problem because it's in an office parking garage with very low overhead clearance. It might sound like poor battery connections -- unfortunately that's not the case.
Any ideas would be appreciated. thanks!

def need to make sure the battery is in good shape. you probably need a better jumper pack. you need to spend 150-200 to get a good one. usually ckicking is a result of low battery when trying to start the car.
