This bulletin applies to 2013-2016 Audi A4, A5, A5 Cabriolet and Q5 vehicles equipped with a 2.0L TFSI engine. The MIL may be on accompanied by DTC P046100 (fuel level sensor circuit range/performance) in the ECM. This DTC can be caused by miscalculations within the ECM software when the vehicle is being filled with gasoline while the ignition is on. New ECM software has been implemented to correct this condition.

Update the ECM J623 (address word 0001) using the SVM action code. After SVM update, cycle the ignition. Start the engine. If it runs rough and then surges, cycle the ignition once again. Reset TPMS if necessary.
