Bizarre Audi A4 oil consumption

First, here are some details on my car:

2009 Audi A4
2.0T Quattro Engine
54,000 miles

I purchased this car a year and a half ago with
33,000 miles on it. Lately the oil has been burning
up at an ALARMINGLY fast rate. I have been
tracking the consumption rate and over the past
900 miles the car has required TWO separate top
offs of a quart of oil (1 quart per top off). The first
top up after my latest oil change lasted only 600
miles. The second top off lasted HALF THAT LONG
(300 miles)..... I know this can be a sign of complete
engine failure, but I am in denial. I have a long way
to go towards my auto loan and was hoping to
avoid a major issue until the car was pushing
100,000 miles. At 54,000 I simply can't believe it. I
was told during my last visit to the dealership that
my water pump had a slight leak and that it should
be okay for now but will need to be monitored.
Could this be impacting the oil consumption? I
would assume not, as the engine never overheats
or smokes. The water pump seems to be doing its
job. I'm lost.

I'm in between jobs right now, and driving my car
for Uber and Lyft is how I am paying my bills, which
makes this whole situation a lot more pressing. Is
my car doomed? There are no visible leaks. I just
had an oil change 1,700 miles ago at the Audi
dealership and have since poured in three quarts. I
know that 2009 Audi A4's were a part of a class
action lawsuit for oil consumption discrepancies,
but that litigation suggested that some drivers were
topping up every 1,000 miles. 300 miles is a major
difference.

Any advice or help would be GREATLY appreciated.

All the best,

Matt
