My Audi has been in the shop all week. I brought it in on Monday because my adaptive cruise control was not engaging properly (the only problem I have had with the car in three years). While performing diagnostics, they determined that one of 36 battery modules was not performing properly and needed to be replaced. Fortunately, the replacement will be covered under warranty but the repair involved removing the entire battery assembly (pictured above) from the bottom of the car. I have been advised that the work will not be completed until early next week.
