Answer 2

hi there,
If the light is on only when you turn on the ignition, this is the preheat circuit which heats glowplugs in the engine and helps the engine to start easily in cold weather, no problem, however if when your driving, the light comes on with 1 of the stop lights on (red or orange) this is a different problem and will have to be checked by someone with a scan tool or Nissan Consult 2.

Answer 3

well wavey line means air intake, could you be more accurate in the descriptions?
