Malfunction Indicator Lamp is on. Climate system heating performance is insufficient. Coolant level warning is on. Engine temperature is elevated. \"Limp Home\" mode is active. Faults are stored in the transmission control module (address word 02). Coolant loss is found from one or more control valves: N82, N509, or N488. Coolant may have migrated into the wiring harness through the connector and into various control units. Climate system heating performance is insufficient due to coolant loss, or due to a faulty N82 control valve. Inspection of the coolant control valves N82, N509, or N488 reveals the presence of coolant inside the electrical connector as shown in the illustration. The connectors, wiring harness, and/or connected control units may have been damaged from exposure to coolant.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2014/MC-10122297-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2014/MC-10122297-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10122297","components":[{"id":"engine","name":"Engine","parent":null},{"id":"cooling-system","name":"Cooling system","parent":"engine"}],"codes":[],"topics":[],"vehicles":[{"make":"AUDI","model":"A4 ALLROAD","year_from":2013,"year_to":2014,"match":"exact","vehicle_ids":["2013_audi_a4-allroad","2014_audi_a4-allroad"]},{"make":"AUDI","model":"A4 AVANT","year_from":2012,"year_to":2012,"match":null,"vehicle_ids":[]},{"make":"AUDI","model":"A5","year_from":2012,"year_to":2013,"match":"exact","vehicle_ids":["2012_audi_a5","2013_audi_a5"]},{"make":"AUDI","model":"A5 CABRIOLET","year_from":2012,"year_to":2014,"match":null,"vehicle_ids":[]},{"make":"AUDI","model":"A6","year_from":2012,"year_to":2013,"match":"exact","vehicle_ids":["2012_audi_a6","2013_audi_a6"]},{"make":"AUDI","model":"A7","year_from":2012,"year_to":2013,"match":"exact","vehicle_ids":["2012_audi_a7","2013_audi_a7"]},{"make":"AUDI","model":"A8","year_from":2010,"year_to":2013,"match":"exact","vehicle_ids":["2010_audi_a8","2011_audi_a8","2012_audi_a8","2013_audi_a8"]},{"make":"AUDI","model":"Q5","year_from":2012,"year_to":2014,"match":"exact","vehicle_ids":["2012_audi_q5","2013_audi_q5","2014_audi_q5"]},{"make":"AUDI","model":"Q7","year_from":2011,"year_to":2014,"match":"exact","vehicle_ids":["2011_audi_q7","2012_audi_q7","2013_audi_q7","2014_audi_q7"]},{"make":"AUDI","model":"TT ROADSTER","year_from":2012,"year_to":2014,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
