Service bulletins for the 2015 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.

| 130514 | 2018-11-26. Service bulletin. ENGINE. . INFORMATION To properly diagnose the customer's complaint, the applicable test plan for the misfire faults stored in the DME must be performed to avoid repeat repairs. If a misfire fault is not stored in the DME memory and an engine related drivability complaint is received, follow the path below to manually start the misfire test plan (AT1214_TVD4_MISFIRE_20): 1. Perform a vehicle test. 2. Select "Function Structure." 3. Select "01 Engine." 4. Select "Engine electronics MEVD." 5. Select "Misfire detection." 6. Follow the steps in the test plan and select "Basic check (start)" first. Do not select "Additional check" at this time. 7. If the result of the "Basic check" indentifies a fuel system component failure, replace the identified component. If the result of the "Basic check" test plan was inconclusive, go to step 7. After the component replacement, perform the "Basic check" portion of the test plan again to verify if the diagnosis was correct and the vehicle condition has been rectified. |

| 112014 | 2018-11-26. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CRANKCASE (PCV). Delivery Stop: Crankcase Failure. A Delivery Stop has been issued on certain 2015 model year vehicles with N20/N26 engines produced from September 4, 2014 through October 21, 2014. These vehicles may have a crankcase failure. Approximately 145 vehicles are affected. |
| B160117 | 2018-11-26. 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." |
| 710214 | 2018-11-13. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:DIESEL; EQUIPMENT:OTHER:LABELS. Service Action: Replace Emission Label. Certain 2015 model year vehicles with N47T and N57T diesel engines were produced with an "emissions" label which contains incorrect information pertaining to the 2015 model year. Affected vehicles in dealer inventory must not be retailed or delivered until this issue is corrected. Vehicles at VDCs will be repaired prior to dealer delivery. |
| 620613 | 2018-11-13. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; ENGINE. Condition Based Service Due Date Is Reset to 01/2000. The Condition Based Service (CBS) due date is reset to 01/2000 and cannot be updated for: * Oil Service * Check Vehicle Note: No fault code is stored Software error in the Instrument Cluster. |
| 161614 | 2018-11-13. Service bulletin. ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM. Service Engine Soon Light (MIL) is On with SCR Fault 805220 Stored. The Service Engine Soon light is on with the following fault stored in the Selective Catalyst Reduction module (SCR). z 805220 - Delivery module, system pressure, pressure build-up is too low. This fault is very likely to be stored at temperatures below 32°F / 0°C if the vehicle is programmed using ISTA/P 3.54.1 or 3.54.2. Unfavorable SCR software |
| 123514 | 2018-11-13. Service bulletin. ENGINE. N20, N26 Service Engine Soon Light On: Fault Code 1B9702 is Stored. The Service Engine Soon light (MIL) is on with only the following fault stored in the DME: ? 1B9702: Engine switch-off time, timer, instrument panel timer DME, Comparison: Value of instrument panel timer too low while engine is running This fault will not cause any engine running or drivability problems. Unfavorable instrument cluster and DME software |
| 123314 | 2018-11-13. Service bulletin. POWER TRAIN; ENGINE AND ENGINE COOLING. Fault Code 1D2008 Stored in DME. The Service Engine Soon light is on. Fault Code 1D2008: Map thermostat: jammed open is stored in the DME. There may also be a complaint of low heat output with lower outside temperatures. CAUSE During the engine warm-up, the engine coolant does not reach operating temperature within the DME's allowable time limits. This is caused by either a faulty thermostat inside the transmission oil heat exchanger or a faulty engine characteristic map thermostat. |
| 123014 | 2018-11-13. Service bulletin. ENGINE AND ENGINE COOLING. Engine Intermittently Will Not Start at Very Low Outside Temperatures. The engine will not start at times at very low outside temperatures (-4°F/-20°C and colder); however, the battery state of charge is correct and the starter turns the engine over properly. This starting difficulty is most likely to occur after shutting the engine off briefly for 5 or 10 minutes, such as when refueling. The following faults are most likely stored in the DME: N20 engine: ? 1B5202 - Terminal 15N_1: No voltage? 1B5302 - Terminal 15N_2: No voltage ? 1B5402 - Terminal 15N_3: No voltage N52T engine: ? 1B5102 - Terminal 15N_3: line from CAS, electric: short circuit to earth ? 1B5501 - Terminal 15N: No voltage ? 1F0601 - Terminal 15N from CAS, switching delay: Switches too lateN55 engine: ? 1B5202 - Terminal 15N_1: No voltage? 1B5302 - Terminal 15N_2: No voltage ? 1B5402 - Terminal 15N_3: No voltage In addition, other engine electronic power supply-related faults could be stored for components such as VANOS solenoids, camshaft sensors, engine oil pressure sensor, engine oil pressure control valve, engine oil level sensor, etc. At very low outside temperatures, low levels of moisture present inside the power distribution module (PDM) can freeze the internal micro-relay contacts. |
| 130314 | 2018-11-13. Service bulletin. ELECTRICAL SYSTEM; ENGINE. Service Engine Soon Lamp (MIL) On with NOx Sensor Faults Stored. The Service Engine Soon lamp (MIL) is on with either of the following nitrogen oxide (NOx) sensor faults stored: * 2B6200 - NOx sensor before DeNOx catalytic converter, plausibility: Sensor self-diagnosis of sensitivity * 2B6300 - NOx sensor After DeNOx catalytic converter, plausibility: Sensor self-diagnosis of sensitivity These stored faults would not cause a problem with engine performance. This NOx self-diagnostic routine is performed only after the engine has been shut off. In some situations, the diagnostic function of both NOx sensors can be too sensitive when sampling the residual exhaust gases, leading to an erroneous fault being set. Unfavorable DDE software diagnostics |
| B123314 | 2018-11-13. Service bulletin. ENGINE; ENGINE AND ENGINE COOLING. Fault Code 1D2008 Stored in DME. The Service Engine Soon light is on.
