My car is sitting in the garage , I open the door and hear a strange rapid clicking sound for 2 seconds from the dash area.

What the heck is that?

It does it everytime.

 

Is your battery fully charged?

 

Yes. ???

 

Fan behind the dash, mine made a noise for awhile then stopped.
I also got a weird gurgling sound with the heat on on a cold day.

 

My car makes this noise without the engine on. Or the key in the ignition. It happens when I open the door and get in.Or stand there listening.
I'm still hoping someone can shed some light on this.

 

Probably the radar detector in your picture.

 

Do you have NAV in the car? I have noticed it in cars with the NAV disk spinning when you unlock the car?

 

Radar unit not on and car is unlocked with no NAV.
It's a clicking sound!!!

 

Probably a rodent. Set a trap.

 

Holger, you're not that far off, I saw two garage queen TT's last yr, both with significant rodent damage.

What a group.

It's an electronic sound.

 

hmmm - reason I asked about the battery was that I observed a similar sound. A friend of mine jokingly suggested that I should charge the battery. Why not, I thought - what could it hurt? - Problem solved. Might be coincidence - I do not know for sure. Nevertheless, maybe an overnight visit by a battery charger could solve your Porsche's aliment.

 

Its the Cd player running mine did it all the time notoriuous prob in the 996's

 

It's not my CD player. Nothing is on or running.

I have now isolated the problem as only occuring when I open the door with closed windows. The noise is coming from the center dash. Clicking that lasts for 1 to 2 seconds.

 

Could it be the relay that lowers the windows a little bit when you pull on the door handle?
