electrical system service required S80

Recently I went to start my 1999 S80 T6 and it acted like the battery was dead.
So I replaced the battery (luckily there was a SEARS in the mall that had a battery that fit....blew me away, actually) and the car started fine and ran great, but about 20 miles of driving later the message center displayed a "electrical system service required" message.
So now I am wondering if the alternator is bad. The car starts and runs great and seems to be outputting current fine, judging by the lights remaining steady even when I turn on EVERYTHING (heated seats, mirrors, rear glass, fan on high speed, crank the stereo...everything), and I haven't had a chance to schedule service, but quite frankly I don't trust my dealer to do ANYTHING right!

Any ideas?

    I had similar problm recently due to weak/dead battery. With a new battery a message: SRS Urgent Service Required. Dealer acknoledged w. dead batteries this is bound to happen. They had to purge existing software and install a new one, $30 parts + 1 hr labor. I was told that you can not reset the system on your own to make the message go away after you remedy the problem w. new battery. It did take care of the problem for now, I am wondering if these two problems are similar/identical.

    You need a voltage regulator.

        This sure is an interesting discussion, especially since i am considering replacing the battery in my 2000. I am a fairly compitent mechanic and didn't think it beyond my capabilities to replace it myself, but now i am thinking i should take to my dealer and have him replace the voltage regulator too>

        My voltage regulator was bad. Dealer replaced it ($499.17) and so far so good.
        I had more weird shit caused by this. I was driving it and all of a sudden all my electrical systems in the car started freaking out. My air conditioner died, the radio died, the windows wouldn't roll down....and I got this message: "total brake failure! Service urgent"
        And then the car locked it brakes up and the traction control went into full ape-shit mode....and then it blew a transmission cooler line and spat ALL of the ATF out onto the ground!
        This friggin' sucked! I had to have it towed ($200) to the dealer and they fixed the broken/blown off line and all that, but they said it was all due to the faulty voltage regulator.

        I tell ya....this car has cost me nearly $3500 in the last 24 months in repairs....and it is not even remotely amusing. I expect FAR more from a car that was just shy of $50K new!
