Under extreme driving conditions, such as a driving profile of mainly short distance (stop and go) driving high crankcase pressure can lead to the above described DTC codes. By changing the crankcase pressure valve to a lower operating pressure this condition can be improved and eliminate the mentioned possible DTC codes. Along with the crankcase pressure being lowered, a new ECM software level is required to compensate for new crankcase pressure.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2012/MC-10122869-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2012/MC-10122869-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10122869","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"AUDI","model":"A6","year_from":2009,"year_to":2012,"match":"exact","vehicle_ids":["2009_audi_a6","2010_audi_a6","2011_audi_a6","2012_audi_a6"]},{"make":"AUDI","model":"A7","year_from":2012,"year_to":2012,"match":"exact","vehicle_ids":["2012_audi_a7"]},{"make":"AUDI","model":"Q7","year_from":2011,"year_to":2012,"match":"exact","vehicle_ids":["2011_audi_q7","2012_audi_q7"]},{"make":"AUDI","model":"S4","year_from":2010,"year_to":2012,"match":"exact","vehicle_ids":["2010_audi_s4","2011_audi_s4","2012_audi_s4"]},{"make":"AUDI","model":"S5","year_from":2010,"year_to":2012,"match":"exact","vehicle_ids":["2010_audi_s5","2011_audi_s5","2012_audi_s5"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
