Hi guys, my 2017 Cupra DSG fwd developed rather weird buzzing / rattle sound when letting of gas.
Strange thing is that it's completely random, no matter if the car is warm or cold. I can hear the sound only on lower gears or reverse. It's always the same short rattly sound. No rattle when the car is stationary. I've also tried to slightly press gas pedal while holding brake in drive, no rattle.

Example of the sound - I've managed to record it. It can be heard in 2nd and 5th second of the recording.

The car runs fine, no judders, no error codes or weird dsg shifs.

Do you have any tips what it might be?

I can't hear it on the video, too much other noise. Is it a very slight rattle? If it doesn't sound like it's something important I'd be tempted to ignore it.
