White smoke is unburned fuel, from one (or more) cylinder not firing.

If nothing else works, pull the injectors and do a compression test.
All cylinders should be somewhere close +/- 10% at most.  While they
are out, test the spray pattern of the injectors.  If you don't have
good atomization the sprayed fuel will be very hard to ignite.

The prolonged running has to use some fuel.  How much and how long you've
run it is hard to guess from what you wrote.

Since I'm new to this list, I'll add as background that I've had a half
dozen VW diesels in the past, including putting aftermarket turbos on
a couple of them.  :-)   If anybody knows somebody looking, I've got
a good '82 Audi 2.0L 5 cyl diesel sitting in the garage that needs a
new home.
