Our 5 door Up GTi didn’t resonate at 1750-2000 rpm
I have found that 80% is the sweet spot setting for the soundaktor ....I had the same issue on my up GTI the other week. Mine had done just over 12k when the noise started. It occurred when revving to around 1900/2000 rpm static or moving. I took it to the garage and explained the problem, they diagnosed it as a sound aktor (actuator) fault leading to increased synthetic noise being sent to the cabin during peak rev ranges, which kinda makes sense as it sounded more like a tractor when I accelerated. They adjusted the volume and I haven't had a problem since! I did laugh that I had to take it to the garage to turn it down....
P.S Don't let them turn it down too much though, half's the fun driving it!
