Ive changed my headlining today and had to take my passenger seat out . On refitting thought id finished but i have a warning B2292 which comes up with safety belt pre tensioner system. The airbag light flashes 3 and 5 . I do seem to have a plug with nothing on it on the uk passenger side but cant remember if i unplugged it or if it had anything plugged in. Could this be the issue ? I clicked the 3 plugs under the seat back so they clicked . Any help would be appreciated Thanks
