MBAG also determined that specific environmental influences in the form of corrosion could have a negative effect on the long-term durability of the diesel particulate filter. This can lead to stresses within the exhaust system which could cause the diesel particulate filter to crack. In addition, in individual cases, it is possible that during repairs to the exhaust system that were unrelated to a defect of the diesel particulate filter, the exhaust system was not replaced in accordance with the MBAG specifications. Specifically, the issue might have arisen where it was necessary for the workshop to replace the exhaust system (including the diesel particulate filter) but that the replacement system was not fitted according to MBAG specifications. This could lead to stresses within the exhaust system which may also cause the diesel particulate filter to crack. In both cases, a fault code is stored in the engine control unit software and the engine diagnostics warning lamp (MIL) is activated. The driver would become aware of the issue due to noise from the exhaust system.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11036889-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11036889-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11036889","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MERCEDES-BENZ","model":"SPRINTER 1500","year_from":2017,"year_to":2018,"match":"base","vehicle_ids":["2017_mercedes-benz_sprinter","2018_mercedes-benz_sprinter"]},{"make":"MERCEDES-BENZ","model":"SPRINTER 2500","year_from":2017,"year_to":2018,"match":"base","vehicle_ids":["2017_mercedes-benz_sprinter","2018_mercedes-benz_sprinter"]},{"make":"MERCEDES-BENZ","model":"SPRINTER 3500","year_from":2017,"year_to":2018,"match":"base","vehicle_ids":["2017_mercedes-benz_sprinter","2018_mercedes-benz_sprinter"]},{"make":"MERCEDES-BENZ","model":"SPRINTER 4500","year_from":2017,"year_to":2018,"match":"base","vehicle_ids":["2017_mercedes-benz_sprinter","2018_mercedes-benz_sprinter"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
