The pcv oil separator has failed and is making a whistling sound. From researching this issue it is widely known and an investigation shows it is caused in relation to a recall for the oil strainer that was done on this vehicle. I called audi dealership and they said this is not an open recall, however it seems this is exactly what caused it.
Driving up an inclined road at night. Car engine started to sputter and jerk and lost power. Was able to get to the side of the road out of traffic at the top of the hill?
