Does it happen at an idle, while the car is sitting at a standstill? Mine will do that, but it can only be heard from the inside of the car. Not from the outside. It sounds like it is coming from in front of the steering wheel? Even when you are not touching anything? If so mine does it every once in a while and I don't give it any mind.
I am just as clueless as you are on this one. But it is a very soft low kind of clunk/pop, and it is not a fast popping it is a slow relaxed sort of rythm.
