2010 add various malfunction lights simultaneously lighting up off and on. Sometimes they go off but eventually come back on

RL09

There was a rumor going around here that it may be the battery.

Is it due?

Seconding RL09, this problem is usually the battery, even if the battery checks out OK on a tester. These cars have a battery that's rather small and underpowered for the electrical demands of the car, and it's common for them to weaken after only 3 years or so. This light show is often the result. A new battery usually fixes everything.

I have lights just like the video at this link. Car is now booked at dealer for an checkup next week in hopes that this TSB solves my issue.

Does this video match your issues?

A friend was complaining of the same problem on his Audi A6 Quattro.

I recommended he try a new battery - fixed that, too!
