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 re-learn the O2 sensor adaptation. Once MVB 41/4 and 136/4 read 0, re-connect the O2 sensors, road test and recheck for faults.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2014/MC-10238591-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2014/MC-10238591-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10238591","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"engine","name":"Engine","parent":null},{"id":"engine-control-module","name":"Engine control module","parent":"engine"}],"codes":[],"topics":[],"vehicles":[{"make":"VOLKSWAGEN","model":"GOLF","year_from":2010,"year_to":2015,"match":"exact","vehicle_ids":["2010_volkswagen_golf","2011_volkswagen_golf","2012_volkswagen_golf","2013_volkswagen_golf","2014_volkswagen_golf","2015_volkswagen_golf"]},{"make":"VOLKSWAGEN","model":"JETTA","year_from":2009,"year_to":2015,"match":"exact","vehicle_ids":["2009_volkswagen_jetta","2010_volkswagen_jetta","2011_volkswagen_jetta","2012_volkswagen_jetta","2013_volkswagen_jetta","2014_volkswagen_jetta","2015_volkswagen_jetta"]},{"make":"VOLKSWAGEN","model":"JETTA SPORTWAGEN","year_from":2009,"year_to":2014,"match":"exact","vehicle_ids":["2009_volkswagen_jetta-sportwagen","2010_volkswagen_jetta-sportwagen","2011_volkswagen_jetta-sportwagen","2012_volkswagen_jetta-sportwagen","2013_volkswagen_jetta-sportwagen","2014_volkswagen_jetta-sportwagen"]},{"make":"VOLKSWAGEN","model":"PASSAT","year_from":2009,"year_to":2015,"match":"exact","vehicle_ids":["2009_volkswagen_passat","2010_volkswagen_passat","2011_volkswagen_passat","2012_volkswagen_passat","2013_volkswagen_passat","2014_volkswagen_passat","2015_volkswagen_passat"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
