My RS is backfiring in normal mode (thought it was supposed to be just sport), don’t think is supposed to do that and what ever you think of the sound its something from an engineering perspective you would want to avoid.
Anyway I called the garage and they say its normal, ‘it’ll back fire over 4k in normal and sport just more aggresivly in sport.’
Is it normal to backfire in normal mode, anyone else had this?
