Anyone else have this? When sat still say at lights, theres the odd click/tick noise which sounds like its coming from behind the dash (i.e behind the speedo etc) - its very random and sometimes clicks 5/6 times in space of a minute, but then will go hours without doing it. Could it be thermostat for air con or something like that?

 

Could be a noisy boost control valve........................

 

Its Subaru paranoia setting in.

 

Do you have meta sat tracking fitted? These can click due to it updating the sat position.

 

I had same problem. Turned out to be my house keys hanging and rattling as on same bunch of keys. Lol

 

Is it the same click you get when your too long from unlocking to turning the engine over, if so it could be just the immobiliser
