dont know why that didnt work , link should be

http://www.audi-resource.com/mmifalsewarn.php

yes your right, the car thinks its got a problem and shuts stuff off, though there is also a small drain which seems undetectable to diagnostic equipment (based on Audi not finding it for 5 days), this drain will kill your battery eventually as it did mine, others seem to have a lot more drain which causes the car to not even start. the enrgy manager is incorrectly calculating the battery.

ive had a hell of a time with this issue for 2 years, so happy now its fixed, not sure on the cost as audi did it for free in the end.

conversation went like this

After 2 days
Tech: there isnt a drain, so we are still diagnosing it
after 3 days
Tech we think we found the problem, your headrest monitors are wired in to the cigar lighter and causing a small drain
me: No thats not it, they have only been there for 7 months, the problem for 2 years
Tech : Ok will take another look
after 4 days
me: where are we
tech: im currently working on whether the battery is coded correctly
me: it is and even if it isnt the battery is new, had the problem for 2 years
tech: oh
me: lets think it through, the car says that the battery is low, is it
tech: yes
me: have you tested the battery
tech: no the car says its low
me: supposing its wrong
tech: the car calculates it
me: what if its not
tech: the battery manager does it automatically
me : what if its wrong, what if its calculations are wrong
tech: im looking for a battery drain
me: what if we dont check that but look at whether the energy manager is lying to us
tech: mmmmm
me : perhaps software version of the ecu
tech: mmm its worth looking at
5 hours later (and after i trawled tsbs etc)
tech: havent found anything
me what about this tsb, for this exact problem that says i need a software update
tech: il take a look
next day: all done, seems to be fine now..

its done by either a dealer hooking you up and running a SVM (Software version management) Update or putting the correct version of update cd in to a VAS505x

apparently the fix also fixes other issues, im not sure what these are

Batman software is 0550 and MMI is 5770. I'm sure it is the radio.
If I get in the and turn the radio on but not the ignition, then turn off radio by holding the volume knob in, then getout and lock the car, the battery will be flat in the morning.

When I check batman quiscent state each state follows the other by a few seconds or minutes I would exprect it to be hours or it's pointless.

Also, how does batman shut stuff down? Does it cut power to terminals or does it just send a CANBUS signal asking them to switch off?
I suspect the radio is freezing on and ignoring the request to shut off.

mmm, your issue is the extreme, the tsb says

if the SW version is between 0270 to 0490 a software change is required,

however the latest software is 0590, so you could still try the update

having said that there was another tsb for the radio causing this problem, will see if i can find it

here it is

MMI High: battery flat, engine doesn't start (closed-circuit current of radio module - MMI2G) Release date: 24-Aug-2009

Customer statement / workshop findings

The vehicle does not start because of a flat battery.

There is a local closed-circuit current of 700 mA in the MOST area (see battery history data).

Technical background

Software for radio module (K box).

Production change

Adapted software version for radio module (K box).

unfortunately the fix seems to be to move to 5570

what software rev do you have on your radio (just in case it didnt update, when you did the update)

Great if this has solved your long running saga. I'll check my software version but I've also noticed a repetitive, intermittant clicking coming from around the rear parcel shelf with the ignition and mmi off which is clearly likely to be coming from the bose subwoofer which might be responsible for my parasitic drain. I'll have to try disconnecting and remeasuring the drain.
