‘13 Q7 with 127k on the clock.
6 gal DEF tank, invoice shows 5 gal added during the fix. ~3,000 miles later the 1000 mile AdBlue warning appeared. Dropped it at the dealer to have them diagnose camshaft chain/tensioner rattle at startup (of course they couldn’t reproduce) They added 5 gals of DEF, no charge (per settlement). Service advisor seemed to agree any camshaft chain/tensioner problems *should* be covered under extended warranty.
5 gal of DEF per 3k, that might get annoying.
