    Hi all, I have been noticing this new sound coming from what sounds like the engine. The best way I can describe it is as a cyclic purr that happens while idling and while driving. The duration and "wavelength" fluctuate. I notice it the worst when I have just pulled in after driving and let it idle in the parking lot. Very audible from inside the cabin. I have attached a video to hopefully help out. The last 10 seconds of the video provide the best example

    That’s strange. These motors are noisy with the direct injection. Is it worse with fan or Ac on? Engine cold or warm? Sounds almost like something vibrating against plastic but hard to hear

    mine is making that same fast ticking buzzing noise, 150miles 2019 CTR.
    it appear to get louder with quick throttle inputs.

    anyone else have the same issue?

    Believe the
    That ticking is not an issue. It happens on the 1.5L too. Believe it's injector/tappet sounds.


    The OP's sound is interesting--sounds like exhaust pipe vibration or pumping sound. You could check the clearance of the front pipe and engine.
    If you get the car up to temp and drive around when it is warm-ish outside, no climate control on whatsoever, does it still make the sound?

    The ticking is clearly the injectors working. Direct injection system is loud, both the high pressure pump and the injectors, as the sistem works as a much higher pressure (~200 bar).
