S3 - Fuel Level Sensor Circ Error
 

Has anyone gotten this "Fuel Level Sensor Circ." Error on their S3? We owned the car for about 7 months now and just scanned it with OBD11 the other day and saw this P046100 fault code popped up. It's shown as intermittent and had occurred 2 times. What is this error and what does it affect? It appeared to me as an emission related thing - am I wrong? Any inputs would greatly be appreciated. Thanks.
