sorry to open an old topic, just I'm having similar problems, getting a dashboard of lights which disappear before i get a chance to look down, and radio sometimes is fine and others drops volume or other times goes off completely. tonight on way home radio went off but still appeared to change station but no sound then after few mins head unit closed and opened again and all was fine. it'll be after christmas before i get a chance to get to a dealer to see what codes she's throwing up so until then does anyone have any idea what might be the cause? bad earth?
