evening all and I know this is going to sound rathee weird but over the past couple of months the engine note on my S3 has changed or more it’s accompanied by another noise, like a shhhhhhh gush (not a whine or a hiss) which increased with the revs. It’s not excessively loud but it noticeable. Definitely wasn’t there before. Performance hasn’t changed, turbo works fine, took it to west London Audi who said its normal but I am not sure how closely it was looked at. Can anyone suggest anything?
