The issue is unresolved at the moment. The error reading is "Reduce Oil Level." It never came on during the first few months we had the car. We have not changed the oil. Therefore, I am inclined to agree with the dealer, who says that this is not uncommon and caused by too many short trips where the car does not reach an optimal temperature.

But it is annoying, and it was, originally scary. I think Audi should do something about it.
