Facelift Rattling noise between 3/4K revs FL S3

[Rolly12]

Has anyone else experienced this? It doesn't appear at all until you get to 3k revs and then disappears after 4k?

Thanks for the reply mate. It doesn't sound like that, at least not from the inside anyway. It sounds like it comes from in front of the driver footwell.

Almost like a hissing sound?
I get a very slight hissing sound at that rev range

Yeah, almost hissing like rattle. Sounds like it could be loads of small metal shavings in a propellor.

Unsure if is there in eco or comfort, only ever noticed it in dynamic. I'll test it out tomorrow and try get a video too and you can hear if it sounds the same.

Have something similar here with my 2017 S3. Increasingly louder rattle from dashboard area in front of driver. For me in occurs above about 3700rpm, loudest at 4K. Has developed within last 2 months.

Most likely the valves. At those revs is usually when they begin to open, I had a tinny / rattle noise until I got them replaced.

The valves are supposedly very weak in these cars and do have a tendency to easily come loose etc. - this is what my exhaust guy had told me anyways.

It's the soundaktor. Go into individual and turn engine sound to comfort it should disappear.
