Hi.Please can any one help me.I have a 2004 3 series compact 2.0td.About a week ago i locked my car and went in doors,when i came out the next morning all of the windows were open and the interior of the car was covered in snow.Since then i am getting a problem with my hazard lights and central locking constantly operating.I have disconected and reconnected the battery and i goes away for a short while (30 mins) then come back.Has anyone had a similar problem and if so what was the cure.Many thanks
