Audi Q7 Battery Drain: Causes & Fixes | Posts 16+

Hello chili1976,

Today, I used the search function to read your posts from December 2014 about a dead battery in an Audi A6 4F.

I seem to be experiencing the same problems with my Q7 and have almost identical measurement results as those you mentioned in your posts.

Unfortunately, this issue was not resolved.

I would like to know what results your research has yielded and what measures were taken to eliminate the problem.

Thank you in advance for your efforts.

Best regards, Willi.

I updated the MMI software. Since then, I haven't seen the "low battery" warning.

Hello chli1976,

Thank you for the quick response.

Did the complaint about the vehicle only relate to the display in the infotainment system (MMI), or did it also include the battery discharging?

Or has the update to the MMI also resolved the issue with the battery draining?

Best regards, Willi.

The complaint was that the car would not start every 3-4 days if it wasn't driven regularly. After the update, it works normally again. At least, there have been no further reports of the issue.
