Need help with Battery
So the past few days I've been getting the "Battery Protection Coven. Functions Temporarily Unavailable" malfunction message on my '04 CPO E55. I decided that since I just got the only a couple weeks ago that I'd stop by the dealer to have them check it out. I've got 2 years/100,000 miles warranty so I figured why not.... Well, 2 hours later, the dealer tells me that I probably have a bad battery. He didn't tell me which one but I told him that I would just replace it.... He informed me that I shouoldn't do it because it's not just that simple...
Depending on which battery it is, can't I just buy a new one? He seemed to imply that if I pull out the battery and put a new one in that I'd would need to have my system reset by the dealer. He said that they get calls all the time because people think that they can just swap out a new battery and end up screwing it up.'
I personally think he full of sh*t.
Please advise. Thank you!

Edit.
Upon further reading I now know that the SA was not completely honest with me. (either that or he thought that I was completely incapable of swapping a battery).
Is there a list of batteries that MBWORLD members use/recommend in their E55's?

I am personally using a main battery from Wal-mart($78), and a gel cell BS-14(~$80) also from Wal-Mart.

have you tested the voltage on the batteries yet? if so, you might want to consider getting a ctek battery charger. I left the fog lamps on last Sat night and didnt take the car out again until Sunday 440pm. Dead, nothing worked. I have a ctek but didnt think it would charge in time for me to go to work monday. So i picked up a battery at the local advance auto for $150 for the main battery. 3yr full warranty, 84 month pro rated. Took out the OEM one and put the new one in. Reset the windows/sunroof myself.
I still need to pick up an auxillary one or just will charge it w/the ctek.

I had similar issue with my car. I ended up replacing both batteries since they were 5 years old anyway. Turned out to be the alternator though. My symptoms were that the sun roof, windows, and radio would stop working, don't know if you have these issues too.

The updated P/N is A 211 540 86 45, but it's not cheap, @ about $550.
