Hi .. I’ve got a new 19 plate Rifter and the engine management light and ad blue flashing light came on .. plus countdown to “no start “ .. taken it to main dealer and they can’t work out what problem is .. fitted new ad blue pump and nox sensor .. still keeps on happening . It’s still under warranty so guess they will keep on trying different fixes ? Just wondered g if anyone else has had this problem and/or has any ideas what’s going on with other it ?
