This may be caused by the hydraulic brake boost function (HBV) in adaptation value 61 being turned off (value = 0). All Passat Wagons (including 4motion) and 3.6L equipped sedans with front drive should have this function turned on (value = 1). Change the adaptation value and verify the fault has cleared. Additionally, it may be necessary to lock the vehicle and allow the modules to go to sleep to clear the fault.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2014/MC-10122626-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2014/MC-10122626-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10122626","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"VOLKSWAGEN","model":"PASSAT","year_from":2008,"year_to":2008,"match":"exact","vehicle_ids":["2008_volkswagen_passat"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
