If the engine is cranked during this check, lowering the system voltage, the ECM may receive an incorrect reading and set incorrect glow plug faults. A production solution is already being implemented for this issue. This document discusses the \"Fault Codes\" necessary to diagnosis, and potential remedy of the issue. The fault codes for checking warranty coverage for servicing the vehicle are also available.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2013/MC-10125820-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2013/MC-10125820-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10125820","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"VOLKSWAGEN","model":"GOLF","year_from":2011,"year_to":2013,"match":"exact","vehicle_ids":["2011_volkswagen_golf","2012_volkswagen_golf","2013_volkswagen_golf"]},{"make":"VOLKSWAGEN","model":"JETTA","year_from":2011,"year_to":2013,"match":"exact","vehicle_ids":["2011_volkswagen_jetta","2012_volkswagen_jetta","2013_volkswagen_jetta"]},{"make":"VOLKSWAGEN","model":"JETTA SPORTWAGEN","year_from":2011,"year_to":2013,"match":"exact","vehicle_ids":["2011_volkswagen_jetta-sportwagen","2012_volkswagen_jetta-sportwagen","2013_volkswagen_jetta-sportwagen"]},{"make":"VOLKSWAGEN","model":"PASSAT","year_from":2012,"year_to":2013,"match":"exact","vehicle_ids":["2012_volkswagen_passat","2013_volkswagen_passat"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
