Service bulletins for the 2007 BMW 328i

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.

0112142018-11-13. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:GAS RECIRCULATION VALVE (EGR VALVE); EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL; ENGINE AND ENGINE COOLING:ENGINE:DIESEL. M57 Diesel Engine Throttle Valve (for EGR): Limited Warranty Extension to 10 Years/120,000 Miles. INFORMATION BMW of North America, LLC ("BMW NA") is extending the limited warranty for the M57 diesel engine's throttle valve (for EGR) on the above-referenced vehicle to: 10 years/120,000 miles, whichever occurs first, as determined from the original in-service date. This bulletin is a notice of a "limited warranty extension." This is not a notice of a Recall or Service Action. There is no immediate repair required unless the BMW vehicle is currently experiencing this problem. Customer Notification Letter - VIN and Component-specific Warranty Extension Even though this is NOT a Recall, BMW NA sent VIN-specific customer notification letters. A sample letter is attached. Eligible BMW Vehicles To assist you in identifying eligible vehicles, the DCSnet Warranty Vehicle Inquiry has been updated with the following "Vehicle Comment," shown below: BMW of North America, LLC has extended this vehicle's M57 diesel engine throttle valve (for EGR) limited warranty to 10 years or 120,000 miles, whichever occurs first, as determined from the original in-service date. Please see SI B01 12 14. Note: Always check the DCSnet Warranty Vehicle Inquiry "Vehicle Comments" and the "Repair History (Claims)" sections first before performing any repairs.

NO REGENERATION OF THE DIESEL PARTICULATE FILTER (DPF) This Service Information bulletin supersedes SI B18 03 10 dated November 2010. . The Service Engine Soon lamp is illuminated. The following fault codes may be stored in the DDE: N47T/N57T engine 245700 - Particle filter system: particulate filter highly loaded (Exhaust backpressure high) 245800 - particle filter system - filter is heavily contaminated. (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
