Hello all,
I own a Cupra 2020 that Ive had for 2 years. It has done 65k miles and Its been modified by me and remapped by R-Tech to just over 370bhp.
The past few weeks I’ve noticed a supercharger/whirring sound. It’s not really noticeable under until over 3k rpm. It makes the noise while stationary and driving.
I’ve found a YouTube video with a golf that is making the exact same noise for reference and put a link to it at the bottom of this post. The comments on the video do not help or say what the fix was.
I have disconnected the vvt magnets and revved the car to 3k rpm and the noise is still there.
Does anyone have any idea what it could be or what to check next? I’ve read comments that say alternator pulley, water pump, pcv valve, timing chain rubbing the guides, balance shafts and some people said they just drive with the noise as it’s supposed to be there and hasn’t caused them any problem. The sound was not here before so it can’t be normal.
Any help is appreciated.
Thanks, Jim.
