Service bulletins for the 2011 BMW X3

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.

B1223192019-08-19. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CATALYTIC CONVERTOR; EQUIPMENT:ELECTRICAL. DIAGNOSTIC HINT: CATALYTIC CONVERTER INSPECTION AFTER LOSS OF CRANKSHAFT SIGNAL. In certain situations when the crankshaft position signal is lost while driving the malfunction indicator lamp (MIL) and an engine malfunction check control message (CCM #29) may be displayed. The engine may run roughly or with reduced power.
B1209162018-12-10. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CATALYTIC CONVERTOR. N20 - The Service Engine Soon Light is On with DME Fault 118602 Stored. The Service Engine Soon light is on (MIL) with only the following oxygen sensor fault stored. 118602 - Oxygen sensor before catalytic converter, fine mixture control: exhaust gas after catalytic converter too lean CAUSE An actual engine related problem and/or DME software diagnostic
B1116152018-12-10. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. N20 and N26 engine: Smoke from Exhaust when Starting a Cold Engine. When starting a cold engine, blue smoke can be seen emitting from the exhaust tailpipe for approximately 10-20 seconds. No turbo charger boost faults are stored and no drivability issues can be detected. CAUSE When the vehicle is parked overnight the engine oil pressure will equalize and may leak past the turbo charger exhaust side turbine seal.
B1116152018-12-10. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM; ENGINE AND ENGINE COOLING:ENGINE:GASOLINE:TURBO/SUPERCHARGER; ENGINE AND ENGINE COOLING:ENGINE:OTHER FUEL TYPES:TURBO/SUPERCHARGER. February 2016 Engine Technical Service This Service Information Bulletin supersedes SI B11 16 15 dated September 2015 SUBJECT N20 and N26 engine: Smoke from Exhaust when Starting a Cold Engine. When starting a cold engine, blue smoke can be seen emitting from the exhaust tailpipe for approximately 10-20 seconds. No turbo charger boost faults are stored and no drivability issues can be detected. CAUSE When the vehicle is parked overnight the engine oil pressure will equalize and may leak past the turbo charger exhaust side turbine seal.
B1601172018-11-26. Service bulletin. ENGINE; ENGINE AND ENGINE COOLING; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. "VOLUNTARY EMISSIONS RECALL CAMPAIGN 17E-A02 - REPLACE ACTIVATED CHARCOAL FILTER AND NVLD SENSOR HOLDER This Service Information bulletin replaces SI B16 01 17 dated March 2017 What's New: ? Bulletin type was changed from a Service Action to an Emissions Recall. The activated charcoal canister and or NVLD sensor holder may be damaged. AFFECTED VEHICLES This Emissions Recall Campaign affects F25 and F26 vehicles produced from February 2017 to March 2017 First check if a Recall Completion Label, SD 92-435 for this campaign is already attached to the underside of the hood on the right (passenger) rear close to the windshield. If the label is present, the Campaign has already been performed and no further action is necessary. Affected vehicles which require this Recall Campaign to be completed will show it as ""Open"" when checked either in AIR, the ""Service Menu"" of DCSnet (Dealer Communication System) or with the Key Reader. LABEL INSTRUCTIONS For California centers only: It is required by the California Code of Regulations that an executed orange ""Vehicle Emission Recall - Proof of Correction"" certificate (SD92-084, see illustration) be provided to each customer (for vehicles registered in the state of California), once the Recall on his or her vehicle has been completed. The activated charcoal canister and NVLD sensor holder are damaged Transportation damage."
1102152018-11-13. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CRANKCASE (PCV). SUBJECT Deleting DME Adaptations After Crankshaft Sensor-related Repairs. The erroneous misfire faults are stored, and the Service Engine Soon light (MIL) illuminates The ISTA Service Function to delete the DME adaptations fails to clear the crankshaft incremental wheel adaptation, depending on the current DME software version. This adaptation must be cleared whenever the following repairs are made: 1. Replacement of the crankshaft position sensor 2. Replacement of the incremental sensor wheel on the crankshaft 3. Replacement of the crankshaft 4. Replacement of the crankcase (block) with pistons 5. Replacement of the engine assembly Due to slight tolerance differences with the new replacement hardware and the original learned crankshaft position, values could cause cylinder balance calculation errors by the DME. DME software (the incremental wheel adaptation cannot be cleared)
B1116152018-11-05. Service bulletin. ENGINE; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. ?N20 and N26 engine: Smoke from Exhaust when Starting a Cold Engine. When starting a cold engine, blue smoke can be seen emitting from the exhaust tailpipe for approximately 10-20 seconds. No turbo charger boost faults are stored and no drivability issues can be detected. Engine oil leakage into the induction system and/or the turbo charger assembly.
B1803102018-11-05. Service bulletin. ENGINE; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. "? 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
