Audi Lane Change Assistant deactivates or is sporadically inoperative when the vehicle is driven in slow-moving stop-and-go traffic, especially on roads with multiple lanes.The message \"Audi side assist unavailable: Sensors blocked\" appears in the driver information system. The system is able to be activated approximately ten minutes after the traffic condition is removed, or after an ignition cycle. DTCs are stored in the Lane Change Assistance control module. Audi Lane Change Assistant can be activated without issue. No obstructions can be found on the outside or inside of bumper. No re-work of the bumper can be found. The control module mounting brackets are securely fastened to the lower rear bumper, and no damage is found on the inside or on the outside rear bumper area. The control module mounting brackets are not broken or loose. In certain normal driving conditions, the Audi Side Assist system can automatically deactivate, and the driver information display shows the \"sensors blocked\" message. This is normal, as the nature of certain driving conditions can make it difficult for the Audi Side Assist system to track vehicles.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2013/MC-10121421-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2013/MC-10121421-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10121421","components":[{"id":"driver-assistance","name":"Driver assistance","parent":null},{"id":"blind-spot","name":"Blind spot detection","parent":"driver-assistance"},{"id":"lane-keeping","name":"Lane departure and lane keeping","parent":"driver-assistance"}],"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":"A5","year_from":2013,"year_to":2014,"match":"exact","vehicle_ids":["2013_audi_a5","2014_audi_a5"]},{"make":"AUDI","model":"A5 CABRIOLET","year_from":2013,"year_to":2014,"match":null,"vehicle_ids":[]},{"make":"AUDI","model":"ALLROAD","year_from":2013,"year_to":2014,"match":null,"vehicle_ids":[]},{"make":"AUDI","model":"Q5","year_from":2013,"year_to":2014,"match":"exact","vehicle_ids":["2013_audi_q5","2014_audi_q5"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
