SERVICE INFORMATION
2009-2015 Jetta/Jetta Sportwagen, Golf, Passat - Oxygen Sensor Reset Procedures
For 2009-2014 vehicles with engine codes CJAA or CBEA:
Disconnect both O2 sensors (front and rear), start engine and let idle. Check MVB's 41/4 and 136/4 and verify have both changed from a 1 to a 0 (you may have to drive the car 4 miles to get them to reset to 0). Also a key cycle may be required for values to reset. This forces the ECM to relearn the O2 sensor adaptation. Once MVB 41/4 and 136/4 read 0, reconnect the O2 sensors, road test and recheck for faults.
For 2012-2015 vehicles with engine codes CKRA, CVCA or CRUA:
Advised tech to go to control module OBD, DTC memory, clear all OBD DTC's and then select basic settings, "Reset oxygen sensor learned values". Road test and reevaluate for any concerns.
