When i pull away in first there is a slight knocking sound as i lift the clutch to the bite. I can't distinguish if this is something to do with the clutch/DMF or just the sound of the exhaust/engine. It's a 12 month old completely standard S3 that i bought used from an audi dealership yesterday (ex-managers car) so i highly doubt it's been messed with i.e. remap, etc. Any help would be really appreciated, hopefully this is normal, if not it looks like a trip to the local dealership. Thanks.
