...because of this
fuck recall, that should be a factory option
fixed with an ECU reflash.
explanation: "The aftertreatment system uses a Diesel Particulate Filer, or DPF, which is designed to collect and incinerate diesel particulate matter that is produced by the combustion process in diesel engines. This process is known as “regeneration†and it is automatically performed under certain operating conditions to clean the DPF and reduce system backpressure caused by the collected diesel particulates. To burn the particilate matter, the exhaust temperature needs to be elevated to around 1100ºF. The 6.4L Power Stroke® engine achieves and regulates this heat by injecting small amounts of fuel during the exhaust stroke as it monitors the exhaust temperatures though the use of three temperature sensors located in the exhaust system. On a couple of rare occasions, a fuel injector or the turbo has failed, combined with the normal regeneration process and produced a flame. These types of failures allow unmetered fuel or uncontained engine oil to mix with the exhaust gasses and ignite if the exhaust temperature raises high enough."
