If your alternator is garbage then turning your headlights on and running your car will drain that ****** till its dead. but before you do that. just make sure there isnt build up on the terminals of your battery that may be causing a very poor connection. as for the throttle body sensor. it may or may not be related. i doubt the two problems are.

2005 buick lacrosse cxl... dash lights and interior lights are going dim to bring to dim to bright very rapidly

First, check that the battery connections are clean and not corroded. If not look for the ground wires that connect to the chassis. Check to see if any are corroded or loose. Finally if that has no effect, you have a short somewhere in your wiring. The easy way to isolate it is to pull the fuses for each device one by one and see if the dimming stops. The last one to cause the dimming is the problem. If it happens when you hit a bump it also might be a ground fault in the interior car grounds....good luck!

The battery/ brake light was caused by the alternator. so make sure the battery is good and good connections. turn the headlights on and be sure they are bright.

Possible problem with the voltage regulator. Call an Audi dealer and ask if that's a separate part or if it's built into the alternator. If it's separate, you could replace just the regulator. If not, you'd have to get the alternator.

Another outside chance is that the load reduction relay in the car is getting screwy, and that may need replacement.
