If there is a low system voltage, the on/off ratio may not be enough to keep the fuel metering valve constant in all areas. In such a situation, the fuel metering valve is deactivated and the high-pressure fuel pump switches to full supply mode. Because the increased rail pressure does not match the respective driving situation, the DTC appears.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2014/MC-10222043-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2014/MC-10222043-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10222043","components":[{"id":"fuel-system","name":"Fuel system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"AUDI","model":"A8","year_from":2013,"year_to":2014,"match":"exact","vehicle_ids":["2013_audi_a8","2014_audi_a8"]},{"make":"AUDI","model":"S6","year_from":2013,"year_to":2013,"match":"exact","vehicle_ids":["2013_audi_s6"]},{"make":"AUDI","model":"S7","year_from":2013,"year_to":2013,"match":"exact","vehicle_ids":["2013_audi_s7"]},{"make":"AUDI","model":"S8","year_from":2013,"year_to":2014,"match":"exact","vehicle_ids":["2013_audi_s8","2014_audi_s8"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
