The following fault codes may be present in the engine control unit: • P3007F1 Leak detected in the intake air system or • P3007F2 Mass air flow malfunction in the intake air system (cylinder bank 1) or • P300CA8 Leak detected in the intake air system or • P300CA9 Mass air flow malfunction in the intake air system (cylinder bank 1) or • P300CA9 and P3007F1: Faults are present simultaneously in the quick test In addition, the customer may report: • An “air leak” type noise from the engine compartment/intake air area, and/or • A “chugging” noise, especially during acceleration or under load. These noise complaints can be present with or without the above fault codes. Cause Causes for FC P3007F1 or P300CA8: Faults are set if: • If there is a leakage upstream of the exhaust gas turbocharger (see \"Dichtring_Sealant.jpg\"). • If the housing intermediate flange at the high-pressure EGR valve (where the exhaust back pressure sensor connects) is carbonized or clogged, or if there is carbonization/incomplete sealing of the high-pressure or lowpressure EGR valves. (See “Gehaeusezwischenflansch_intermediate_flange.jpg” and verstopfter_Gehaeusezwischenflansch_clogged_Intermediate_Flange.jpg.”) • Note: Only relevant if the correction value in load range 1 is less than -8%. • If the intake manifold (charge air distribution line) or charge air cooler is carbonized (see \"Saugrohr_intake_manifold.jpg\"). • If engine timing is misadjusted. • There is a defective hot film mass air flow sensor or a hot film mass air flow sensor that is affected by incorrect airflow (this can be due to a clogged or deformed air filter). Refer to the attached file \"Luftfilter_air_filter.\" Cause of fault code combination P300CA9 AND P3007F1: Faults are set if: • There is carbonization or incomplete closure of the high-pressure exhaust gas recirculation valve, especially in the housing intermediate flange at the EGR valve (linked to the exhaust back pressure sensor). Charleston Plant Identification – VIN 11th Digit “T”: For vehicles produced at the Charleston Plant (identified by “T” in the 11th digit of the VIN) with a production date on or after 12/20/2023: • If fault code P3007F1 or P300CA8 is set, an air leak is found, and the cause is identified as a loose or mis-installed Clean Air Line from the factory, open an Initial Field Quality (Info Only) case. • Include the current Quick Test and photos showing the Clean Air Line issue. For all other vehicles, continue diagnosis as per the standard instructions.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11028117-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11028117-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11028117","components":[{"id":"engine","name":"Engine","parent":null}],"codes":["P3007","P300C"],"topics":[],"vehicles":[{"make":"FREIGHTLINER","model":"SPRINTER 1500","year_from":2023,"year_to":2024,"match":"base","vehicle_ids":["2023_freightliner_sprinter","2024_freightliner_sprinter"]},{"make":"FREIGHTLINER","model":"SPRINTER 2500","year_from":2023,"year_to":2024,"match":"base","vehicle_ids":["2023_freightliner_sprinter","2024_freightliner_sprinter"]},{"make":"FREIGHTLINER","model":"SPRINTER 3500","year_from":2023,"year_to":2024,"match":"base","vehicle_ids":["2023_freightliner_sprinter","2024_freightliner_sprinter"]},{"make":"FREIGHTLINER","model":"SPRINTER 4500","year_from":2023,"year_to":2024,"match":"base","vehicle_ids":["2023_freightliner_sprinter","2024_freightliner_sprinter"]},{"make":"MERCEDES-BENZ","model":"SPRINTER 1500","year_from":2023,"year_to":2025,"match":"base","vehicle_ids":["2023_mercedes-benz_sprinter","2024_mercedes-benz_sprinter","2025_mercedes-benz_sprinter"]},{"make":"MERCEDES-BENZ","model":"SPRINTER 2500","year_from":2023,"year_to":2025,"match":"base","vehicle_ids":["2023_mercedes-benz_sprinter","2024_mercedes-benz_sprinter","2025_mercedes-benz_sprinter"]},{"make":"MERCEDES-BENZ","model":"SPRINTER 3500","year_from":2023,"year_to":2025,"match":"base","vehicle_ids":["2023_mercedes-benz_sprinter","2024_mercedes-benz_sprinter","2025_mercedes-benz_sprinter"]},{"make":"MERCEDES-BENZ","model":"SPRINTER 4500","year_from":2023,"year_to":2024,"match":"base","vehicle_ids":["2023_mercedes-benz_sprinter","2024_mercedes-benz_sprinter"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
