Service bulletins for the 2016 BMW 320i

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

(exhaust backpressure is above maximum) M57Y engine 480A Particle filter system - filter is heavily contaminated. (exhaust backpressure is too high) 481A Particle filter system - filter is heavily contaminated. (exhaust backpressure is above maximum) CAUSE 1. Faults with the exhaust system that affect the monitoring of the DPF by the DDE 2. Unfavorable recent driving profile INFORMATIOM During normal driving, there is a continuous regeneration of the diesel particulate filter that takes place at exhaust-gas temperatures between 280 and 350°C (slower oxidation process). The soot particles can only be burned off when the required exhaust-gas temperature has been reached. Under certain driving conditions (i.e., prolonged short trips or an exhaust system which never reaches soot burn-off temperatures), the DPF can become restricted. The DDE will initiate periodic regeneration automatically, at the latest after 600 miles. In vehicles making many short distance journeys, periodic regeneration takes place after only 250-500 miles. The Digital Diesel Electronics control unit evaluates the time for periodic regeneration from the following values: average distance driven average driving speed temperature in the diesel particulate filter values from the exhaust pressure sensor The DDE initiates the regeneration process by decreasing incoming air by the throttle valve, and one or two post injections are executed. This heats the exhaust-gas temperature to approx. 600° C . When the exhaust temp reaches this point: The soot is burned off with the residual oxygen. The
