Thanks Flobble ive replaced nox sensor 2 as instructed by ODIS, but have since learned nox sensor 1 may be faulty (giving low readings) which causes the diagnostics to believe sensor 2 is reading incorrectly. currently running tests. Will post update. for reference this vehicle has no battery issue

Flobble.. Hi, did you get this issue resolved? We have a SQ7 with same issue. After repairs around 50-100 miles the Ad-Blue shut down reactivates where it left off. Most recent warning went straight to Red warning - restart not possible, without any countdown
