The addition of the insulation blanket will maintain higher exhaust gas temperatures within the SCR, which may improve performance and a potential to reduce the occurrence of after-treatment related engine codes, and that MCI will remedy the affected coaches at no cost to the owner.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2018/MC-10133200-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2018/MC-10133200-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10133200","components":[{"id":"fuel-system","name":"Fuel system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MCI","model":"D SERIES","year_from":null,"year_to":null,"match":null,"vehicle_ids":[]},{"make":"MCI","model":"J SERIES","year_from":null,"year_to":null,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
