Hello everyone, here is an update:
The noise is indeed more pronounced when the engine is cold. Unfortunately, my car dealer did not find the cause and referred it to a DSG specialist. They concluded that the dual clutch plate in the transmission was generating the noise, and they repaired/revised it. I have been without my car for almost 2 months in total, but the noise has completely disappeared. This was an issue that had never occurred before for the DSG specialist, the car dealer, and CUPRA itself.
These repairs have helped me, and I hope they can
help you too. They first listened to my car with equipment and noticed that the issue occurred in third gear. Ultimately, the
problem was with the clutch plates in the transmission. I also requested a diagnostic report; if I receive it, I will share it with you.
