Peugeot boxer 2011 base Autocruise Starfire. Had a spare key remote created requiring technician to reset battery earth, as they apparently need to do... When finished had yellow Passenger airbag light on. Seems the reset disabled the passenger airbag. I enabled it via the Mode options, panel buttons right side of steering wheel and all good. After researching others problems and the commonality of it on MHFun I felt dread thinking ECU corruption or worse so really relieved and glad.
