I've got a gentle ticking/clicking noise every now and then when I am driving slowly in the lower gears (my 370z is an auto) with windows down. It doesn’t do it when I’m sat idle and it either doesn’t do it or I can’t hear in the higher gears or at speed. It sounds like it’s behind me & underneath the car sort of area. It’s quite faint, the only thing I can compare it to is a hot exhaust ticking you get when your turn the car off, that sort of sound, but this is a more prominent.
The car is driving fine, it’s just doing my head in and want to know what on earth it could be.
