MIL on. DTCs are stored in the engine control module (ECM). Under extreme driving conditions (such short-distance, stop-and-go driving), high crankcase pressure can cause the DTCs to appear. The condition can be improved and the DTCs eliminated when the crankcase pressure valve is changed to a lower operating pressure and the ECM software is updated to compensate for new crankcase pressure.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2013/MC-10121398-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2013/MC-10121398-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10121398","components":[{"id":"engine","name":"Engine","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.
