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.
