I'd like the chime in here. We just got our 35d back after 2 days, and this is the explanation of the exhaust fluid being low.

Found Active Tank was possibly frozen.
PUMA case: 283858xx (I don't know if saying the whole number will show some private information.)
Ran short test and found CC message 492 stored for active tank needs topped off. Checked levels and found active to be at 100% and passive to be a 67%. Contacted PUMA and was instructed that the active tank may freeze in sustained cold and thus read incorrectly that active is empty and that from time to time the active tank might need to be topped off manually during the colder months. This is normal operation and can be referred to in the owners manual.
