I am sure I read on here that chaffed wiring due to poor routing was one of the problems with failing NOX sensors, and had to be re routed to resolve the issue.Apparently they checked some wiring, though looking at my receipt the fault had been diagnosed on Star-so not sure what they were trying to achieve.
Maybe they had to resolve this first before the Software update could be done. Might be worth asking the question of Mercedes to see if they are prepared to offer any goodwill.
