steveandmaddz Posted February 6 Share Posted February 6 I have a 2019, A6 Allroad and the yellow engine warning light has come on. Upon interrogation the msg ‘Bank 1, Sensor 2’ comes up indicating a faulty Nox sensor. Ideas of what to do and where I can buy a spare part at reasonable cost? thank you steve Quote Link to comment Share on other sites More sharing options...
