Question: Starting the vehicle

When I got to start the vehicle, I get a slight pause and it seems to labor for a second (like a dead battery), but then it starts up and drives just fine. The car does sit for long periods (sometimes weeks) and the battery is the original (6 years old).

Your local shop can probably run a test on the battery. They tend to go out at about this time.

Otherwise, being a full time Audi technician, I know that a small delay is normal on these and newer models. There are a dozen things that happen when your turn the key to start before it actually engages the starter. From key RFID chips being read to immobilizer computers synching up and load reduction relays clicking on... these cars are complicated to say the least.

If the battery tests bad or weak, replace it with a factory style unit. If the condition remains, I wouldn't worry too much unless it gets worse etc.
