[Debacle of Mass Eruption.]

I was driving down 101 near Palo Alto and I hit the gas to change lane, right after I did that I noticed something weird. My gas pedal was unresponsive and a crapload of lights lit up my dash, so had to exit and pull into a parking lot. I opened my hood and noticed my coolant tank was boiling and leaking, the cap had corroded seals, I have since replaced it.
I cautiously drove it home after adding some water. I looked it up and my battery was DONE, this was later confirmed the next morning when my car wouldn't open and I had to go through the trunk. I bought a new Bosch AGM battery from PepBoys (it's was an ordeal) with higher CCA , around 800. I just installed it this afternoon after looking at a demo on E90Post.
After everything was secured, I turned on my car and everything was GREAT, for about 2 seconds until all the symbols reappeared, with also a new window symbol. I tried to clear the codes myself, but to no avail. I tried to drive, but 1st gear was unresponsive.
Does anyone know what this might be and/or how it may be resolved?

UPDATE: Brand new battery dead after one day. I tried to use by battery charger, but it kept surging for some reason...

Hello. New member here too as I have just bought my 325i last week.

From what I read here, it sounds like your water pump has gone bad and you are in limp mode.

I'm from San Mateo btw! Sorry if I couldn't help much.

Edit: similar thing happened to my ML with all the lights coming up. It was the alternator.

Brand new Battery installation needs to be coded.

I'm fairly new to BMW, and I'm not a mechanic at all but If the battery doesn't charge..Isn't it the alternator. As far as coolant boiling out, Maybe the water pump / thermostat isn't working properly.
