I have a 2012 Optima LX with the 2.4 L 4 cylinder engine.
Whether the car is cold or hot, I can hear a continuous tapping/clicking noise from the top of the manifold area (I cannot pinpoint where the noise is) when the "accessory" is turned on before starting the car.
The noise is not noticeable from inside the car, but if I pop the hood then you can hear it when standing beside the engine bay.
Car seems to start/run fine.

Something to worry about, or is this normal?

i just noticed the exact same thing today while i was adjusting my waste gate rod (again 馃槕). i don鈥檛 remember it making that same ticking noise when i had to adjust that stupid rod back in march. these cars seem to protest, vehemently, all winter long while the temps are really low. it may just be one of those kia winter wonders 馃檮

hopefully someone else will have an answer for us!

UPDATE:

Had my car in at the dealership a few days ago for some work and specifically asked about this issue.

Mechanic said it is the purge solenoid-normal and nothing to worry about. (y)
