This because the noise from your engine is louder than the noise that is coming from the radio/centre console. Since 335s have low end torque, even at 1000rpm, the noise from the engine will be louder than the weird noise from the centre/radio console hence you think it's gone when it's actually still there. When you don't throttle, and your car is just cruising, the noise will appear again. Or when you are at a light, you'll hear it as well.
