Battery Issues??

[RustyZzipper]

Im at a loss and my car is frustrating the shit out of me.

About 6 months ago my MMI screen stopped tucking away when turning off car and simultaneously the front and rear camera stopped pulling up when in reverse.

Month after those symptoms my car died. After jumping the car the issues where gone and that lasted about a month. So I figured its related to low voltage. I had the battery replaced and now the issues are still occurring. My car even died again after sitting for 4 days (in garage), proceeded to jump the new battery and issues were gone once again. That lasted about half a day. I do not drive far distances during the week but usually go on drives on the weekend. Dont know if that is a factor.

Any input would be appreciated!

Did you recode the new battery so it's getting charged correctly

I posted on FB....you may have a vampiric draw

have you done any electrical maintenance?
wired anything up?
bad terminals
major maintenance
anything tethered to the OBDII Port or constantly plugged in to the OBDII Port?

Not specific to your issue but lightly driven cars won't do well with battery charging. This is my TDI, sits outside and doesn't do too much driving but you can see the health drains over time. 100% periods is when I've left it on the charger in the garage. Battery was new from Audi within the last year so new doesn't absolultely guarantee worthiness.

Mmm. Make sure you got a good replacement battery to begin with, many are junk even when new. Needs to be tested and charged before it's installed. Make sure it's coded properly when installed.
Drive longer distances if you can.

My passenger mirror dips in reverse, but sometimes doesn't return to the normal position after setting off (supposed to above 8 or 10 mph).
Also my MMI can sometimes take a long time to start up, or respond.
On a few occasions, the screen wouldn't pop out, but it's not broken.
I'm getting odd TPMS messages about all 4 tires being low, when only one is, or even when none are.
I'm thinking it's battery, it's original at 6 years old, and the car stays parked outside at an airport for days on end and then gets a long 2 hr drive right away.
That said. It's never NOT started right up, and everything seems to work correctly apart from the few weird things....

Is your MMI still broken? There is an AZ thread about broken wires to the MMI motor. I suppose if the wire is broken it might also periodically short out and drain the battery. If you have the ability to scan for fault codes with VCDS or equivalent, you should post the results here so the knowledgeable folk may provide better advice.
