- [SSM 51691](/bulletins/10237789.md), 2023-06-16, Service bulletin: ENGINE AND ENGINE COOLING:EXHAUST SYSTEM; POWER TRAIN. 2011\-2023 F\-Super Duty and 2016\-2024 F\-650/F\-750 vehicles equipped with a 6.7L engine may exhibit an elevated idle condition. During prolonged idle time, vehicles may experience this elevated idle to reduce unburned hydrocarbons from the SCR. The powertrain control module estimates hydrocarbon levels in the SCR and may increase idle speed to remove them. Idle speed will be increased to 1000 RPM for ambient temperatures near 26°C \(80°F\) and may increase to 1200 RPM at \-40 °C \(\-40°F\). Vehicles may exhibit exhaust smoke and diesel exhaust fluid smell during elevated idle condition. Exhaust smoke and smell condition will not affect reliability or durability of the engine. Power take\-off \(PTO\) use and idle set point control will disable elevated speed. It is required that the operator monitor the vehicle and adhere to any Exhaust Filter warning messages.
- [SSM 51251](/bulletins/10228867.md), 2023-01-05, Service bulletin: ENGINE AND ENGINE COOLING. Some 2011\-2022 F\-Super Duty vehicles equipped with a 6.7L diesel engine may exhibit a ticking noise at idle after an engine oil change. It is often referred to as Typewriter Noise because of its similarity to the sound of a mechanical typewriter. When engine temperatures reach 150 °F \(65 °C\) or higher, \(from engine idle up to approximately 1700 RPM's\), this noise can typically be heard at the front wheel well and is often isolated to the transmission bell housing or oil pan area. Typewriter Noise is not detrimental to engine function or durability and has no short or long term effects on the engine. Do not attempt repairs to eliminate this noise. This noise is characteristic of the 6.7L diesel engine and will typically cease or diminish significantly within the oil change maintenance interval.

Diagnostic trouble codes \(DTC’s\) for EGR cooler efficiency below threshold \(DTC P0401\) and/or insufficient EGR flow at idle \(DTC P2457\) are stored when the malfunction indicator light is illuminated.
