The car does not have any lights on the dash and no codes the rpm’s have a small jump every time the car pulses the car has new spark plugs and coil packs .—— I have posted a video below, that is what it is doing.

any ideas??

Is there supposed to be a picture (like of the RPMs) or the video is just sound? I am asking because my device might not be playing it correctly?

It’s just the sound, it’s playing correctly lol

be careful when opening questionable video files, if it doesn't play on the browser and you have to download it to play it's a red flag.

Hmmm, do you notice any fluctuations in RPM? If so, can you video tape the tachometer for us to see?

Edit: The sound is loudest which side of the engine? Is the sound audible in the cabin?

The rpm’s don’t jump unless your going from Drive to reverse which I think is normal to do not sure it’s more of like a pulse feeling every time it does it

Appreciate the heads up I will be more careful next time.

OP, I recommend uploading the video to youtube and hopefully someone that came across the noise will therefore chime in.

bruh I ain’t no hacker, I’m just trying to find this problem out it’s a normal video

alright I will try that, thank you!

I mean I understand why people are reluctant to download videos, maybe that is why no one commented on your thread yet (I personally haven't been on the forums often and just saw your thread). Is the sound louder when engine oil is cold or warm and is it louder on one side of the engine?

So when the cars warm it doesn’t do it at all, it only happens when the car is warming up and getting too operating temperature. It also only does it in comfort mode, it doent do it in S+ or race mode

I know this might sound cliche but.... no codes right?
