Audi S3 Sportback 8P
Hi, newbie here and this might well sound stupid.. I've just picked up a 2011 DSG S3 Sportback which I'm in love with. Everything seems fine performance wise etc other than a strange noise which seems to be coming from the Revo intake under the bonnet when accelerating. It almost sounds like a grinding noise but I'm thinking it could also just be the noise off the intake suckling in cold air as its not a closed unit like the OEM box? So basically is this normal to sound like that or not. Any help is appreciated thanks.
