2007 clicking noise

105k miles on my x3.. Started hearing consistent clicking noise coming from the front of the car.. It seems that intervals are pretty consistent, about 10-15 seconds.. Any ideas?

Does it vary with vehicle speed?

If the vehicle is stopped, it at least narrows it down to something engine-related. Could be anything from lifters to fuel injectors to rattling belt tensioners... my E46 had a "ticking/clicking" that I discovered to be a drive belt tensioner mount so loose that it was wobbling against the block.

This is a long shot, but when I had a clicking sound it turned out it was a defective heater fan, not from the engine compartment at all, just sounded like it was.

That's what I was thinking too. Haven't had that problem myself, but I think it is often described as a cricket sound.

Another possibility is the engine cooling fan with a bearing going bad or maybe the multi-speed switch module having a dirty contact.

secondary water pump? (heater pump, whatever you want to call it) see if it goes away when you turn off your heater

Can you hear the sound from outside the vehicle with hood up or just inside?

If outside...An 07 in jersey at this time if year...I would say ticking valve lifters or electric fan.

But if only inside, the heater fan is a great potential source.

That seems to be too long an interval for engine-related 'ticks' (belt tensioners, lifters, etc.); the chirping/squeaking/ticking for those things happens much more rapidly. I admit I'm not familiar with the sound of the engine fan ticking, though... Or am I misunderstanding what you're saying here about the interval between sounds...?

Its not valve lifters, I know what those sound like. Consistency of it, ticking every 10-15 secounds is what makes me think that it is elctrical. Listening under the car for a few minutes it was more audible in the radiator area... I will check the radiator fan. Could it be water pump?
