Fuel Level Too Low

on 2012 Audi A6 3.0L Supercharged V6 · AWD

What this code means

The ECU detected that the fuel level is critically low. Running the fuel system with very low fuel can cause fuel pump overheating, air ingestion, and lean running conditions.

  • Check Engine Light
  • Possible engine stumble

Common causes

  • Fuel level genuinely low
  • Faulty fuel level sensor
  • Wiring issue to fuel level sensor
  • Fuel gauge malfunction

Diagnostic steps

  1. Check actual fuel level visually
  2. Test fuel level sensor resistance
  3. Inspect wiring to fuel tank
  4. Check fuel gauge operation

Repair notes

Refuel the vehicle; if code persists with adequate fuel, replace the fuel level sensor.
