16684/P0300/000768 - Random/Multiple Cylinder Misfire Detected

Possible Causes

  • Air Intake System leaking
  • Fuel Supply faulty
  • Injector(s) faulty
  • Ignition Cable(s) and/or Spark Plug(s) faulty
  • Ignition Coil(s) faulty
  • Exhaust Gas Recirculation (EGR) Valve (N18) stuck/open
  • Camshaft Position Sensor (G40) faulty

Possible Solutions

  • Check Misfire Recognition
  • Check Air Intake System for leaks
  • Check Fuel Supply (pressure, quality, delivery quantity)
  • Check Injector(s) and Injector Sealing
  • Check Ignition Cable(s) and Spark Plug(s)
  • Check Ignition Coil(s)
  • Check Engine Speed Sensor (G28)
  • Check engine compression
  • Check for Carbon buildup (compression too high)
  • Check for valvetrain concerns
  • Check Exhaust Gas Recirculation (EGR) Valve (N18)
  • Check Camshaft Position Sensor (G40)

Special Notes

  • This DTC indicates that one or multiple cylinders are misfiring, but the ECU fails to identify the cylinder.
  • When found in 2008-2013 A3, TT and 2009-2013 A4, A5, Q5 and A6 vehicles with the 2,0l TFSI (EA888) engines it maybe necessary to Reset the Misfire Adaptions.
    • As per TSB [01 13 73] | TPI [2033223] - 01 Engine warning light on after engine replacement EA888 2.0 TFSI
    • To Reset Misfire Adaptions: Clear the 01-Engine fault codes three times in a row in less than 29 seconds "to remove the programed values."
  • For the Tiguan with the 2.0T DGUE engine that has one or more of the following fault codes, please see TSB 054615 for possible ECM update and hardware update.
