Default BEM (battery energy mgmnt) SW update ?

I am getting my battery coded today in an effort to resolve battery issues. But I am wondering if I should also do the SW update to the BEM that was in a tech bulletin. I have a 2004 A8.

The bulletin states the problem as AMI Batt level reading 10% because something in the BEM drains the battery. I have had 10% reading on the AMI the last to mornings (temp 10F) and the battery measured 11.9V with the multi-meter both times. Nominal reading on my car's battery is 12.2V so 11.9V would not be 90% less would it ? And last nite when I got in the car to go home the MMI read 10% and after the drive home it still read 10% but the battery read 12.2V. So something is not right

Has anyone done the SW update ? Or know how its done ? I have the proper CD disc for the update...is it just a matter of putting the disc in the CD player and following prompts the same way the MMI upgrades are done ?

And if youve done the upgrade did it change BEM behavior?

AFAIK, the update to the BEM is via the official Audi VAS system and a connection to the GeKo servers in Germany. The procedure is called SVM (Software version management).
I stand being corrected though, what CD do you have?

I've got a quick question: On my '07 I've never been able to locate any battery meter. After checking through all the tabs in the MMI, still no luck. Maybe mine was turned off or something?

I could not get the CD (4E0 906 961 G) to work in my CD player. I thought it would play the way the MMI update CDs did. But this one identifies on the screen as CD-ROM, but does not do anything.

And I see on the disc it says VAS 5051/5052, but I did not know what VAS meant. So I have to go to the dealer to get the SW upgrade ?

Snap is correct, I have had it done, the cd goes in to the VAS system that many indy garages would use, or as i did go to a main dealer, it took them about 15 minutes to do. you will need to be specific about what you want and quote the TSB number. ask them to recode your battery after just to make the BEM reset itself.

see here http://www.audi-resource.com/mmifalsewarn.php for full details

it cannot be done via the mmi

I just called the Audi dlr and the service guy said they just did one the other day so he was aware of what I need. And he said they charge 2.8 hours for that upgrade!!! And I asked how long it actually took to do and he said a couple hours.

CAlled another Audi dlr and they say 1-1.5 hours which is less money but still a surprising amount of time/money for a download that is not a multi-disc task like the MMI update. Are you sure it only takes 15 min in reality to actually complete thye process ? 'Cause if thats the case I would think I would be justified in raising thy issue with Audi USA since it is a defective 'part' from the factory and, even though out of warranty, its not right that I should pay $300 to correct.

You should complain, otherwise how will AoUSA know how bad the dealerships are in the US?

its very quick, they did it free for me beacuase they kept diagnosing it wrong and it was i who found the tsb, maybe it takes a lot less time when they arent getting paid

it only takes 45 minutes to do the latest mmi upgrade, they charge an hour though (sometime 1.5 hours), at the main dealers they dont even have to load the cd, its already a part of their system, they only have to select the update.

even if it took 2.5 hours they only need to start it off then walk away until its complete, only a few minutes work in real time


i would complain anyway, and if you can find an indy dealer with VAS take your cd in and ask them to flash it, will be a lot cheaper.

You can get VAS-PC and do it yourself. Other "only dealer" things too. Except ones that need online connection to Audi. Just don't ask me how. You have to find that yourself.
