2017 s3 buzz

[Ben2960]

Hi guys,
I have a 2017 s3 which I have had from new after about 3 months of ownership I started to get a buzz noise at 2.5k revs which is intermittent, the car can be in motion or at stand still. I am now into a year of ownership and still have the noise after visiting all of the local audi dealerships they cannot seem to locate the source of the noise. The dealership I perchased the car from have now washed there hands with me, they tell me that the car runs within spec so I am to put up with noise. They have refused to accept my rejection of the car. What are your thoughts on this and is anyone else getting this noise??

Does in only do it in dynamic mode? If so, soundaktor is faulty.

Nope does it in all modes

I had the same issue, turned out to be fuel pipes in the engine bay. Fixed under warranty

edit - fuel pipes vibrating, I have the paperwork at home if you need more info
