Possible Causes

  • Fuel pressure
  • Running out of fuel
  • EVAP canister purge valve
  • Evaporative emission system

Special Notes

  • This feature search for engine misfire in a specific cylinder. Most of the time the cause for a misfire is a lack of combustion in a cylinder due to absence of spark, poor fuel metering, or poor compression.

  • 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 30 seconds "to remove the programed values."
