I have a hard time believing this noise is anything serious. If a bearing was faulty, wouldn't there be other symptoms, like rough idle or loss of power or something?
God I wish I had never looked at this thread...
Hrmm... Yes, mine is also erratic... i.e. irregular. It also sounds exactly like the sound of exhaust cooling. Although the technician agreed that it wasn't, as it went away after the car stopped running, I have to say that I don't have any other issues/errors other than this particular ticking/clicking... yet.
I will reserve my judgment on whether this is serious or not, as it could be a symptom of something serious. I have to admit though that, when I first encountered this noise, I had the same thought as you did, i.e. that it couldn't possibly be serious.
I am dropping off my car tomorrow for a full diagnostic test; the foreman will hopefully be able to figure out what the problem is.
