No idea whats wrong with my Subie. Help needed.

Hey guys. I'm still fairly new to the forum and I'm in desperate need of assistance.
Today I've been extremely busy at home and haven't driven my car at all nor started it. later today I had to drive my older brother home to Sydney and took my dads ute because my Subaru needs a service its about to hit 100 000k's. When I got home my dad told me the alarm had been going off on my car constantly while I was gone and it wouldn't stop, so I went and had a bit of a look. everything seemed to be normal and in order, but when I put the key in the ignition and went to start the car it had different plans. The whole dash board was flashing and wouldn't let me turn it on. I wait about five minutes and it started but the dashes was showing the check engine light, the battery light, the little water light, the traction control light, cruise control was flashing on and off, the car was stuck in sports mode on the SI drive and it wouldn't go to sports sharp no intelligent, it just kept making the beeping sound. It seems to have gone into some kind of limp mode. I haven't driven the car because it's late and I'm worried i won't make it home.
Does anyone on here have any clue as to whats going on with the car. Is there a quick fix or do I need to take it to a Subaru specialist. This is the first problem I have had with the car since owning it apart form the power steering pump.
It's a Subaru Liberty 3.0R Spec B, 2007 model with about 98650k's on it

It's a check engine light (CEL). Read the tune link in my sig, get the code read and take appropriate action
