Hello all, I hope someone can help me here!



I have a noise in my vehicle, which occurs irregularly, that I think corresponds to normality, because I hear the same noise in very many vehicles in traffic.



Namely, arises at short gas shocks when driving or especially when downshifting with pressed sport button, as soon as the engine initiates the intermediate throttle, a short, unique clacker noise. In many older vehicles, you hear the same noise as soon as you apply the accelerator. After a long search in this forum and generally on the internet, I could not find where exactly the noise can come from. ? :-(



I guess it comes from the clutch, flywheel or thrust bearing area. The noise usually comes from age, however my vehicle has only 28'000 km.

Vehicle: 981 GT4


I found a video of the sound on YouTube, which sounds exactly the same. You have to hold the video close to the ear that you hear it. Is the short clacker noise at the gas push.

Only with my GT4 comes this noise irregularly as soon as the engine initiates the automatic intermediate throttle or at the gas push.

I'm pretty sure that's just intake plenum noise as the throttle body is opened quickly.

so is that normal or should I be considered thats something is broken?

Normal. most engines do this. It's just easier to hear on Cayman/Boxsters with the routing of the intake tract.
