CAUSE When the vehicle is parked overnight the engine oil pressure will equalize and may leak past the turbo charger exhaust side turbine seal.
B0703142018-12-10. Service bulletin. ENGINE; STEERING; ELECTRICAL SYSTEM; EQUIPMENT. This Service Information bulletin supersedes SI B07 03 14 dated October 2015. Diagnosing Stored Fault Codes to Help Avoid Repeat Repair Visits. Fault codes stored in vehicles being serviced are not being diagnosed, leading to repeat repair visits (source- Analysis of FASTA data and repeat repair visit reports). INFORMATION Where diagnosis (vehicle or short test) with ISTA has already started, it is important to diagnose the fault code(s) listed below (when they are stored in the vehicle) to find their root cause during the current workshop visit. This will help lead to a reduction in workshop repeat repair visits and higher customer satisfaction.
B1111152018-12-10. Service bulletin. ENGINE AND ENGINE COOLING; EQUIPMENT; EQUIPMENT ADAPTIVE/MOBILITY. ?SERVICE ACTION: REPLACE THE THERMOSTAT New information provided by this revision. Please perform the procedure outlined in this Service Information on all affected vehicles before customer delivery. In the event the customer has already taken delivery of the vehicle, please perform the procedure the next time the vehicle is in the shop. This Service Information bulletin supersedes SI 11 11 15 dated January 2016.
B1111152018-12-10. Service bulletin. ENGINE AND ENGINE COOLING:COOLING SYSTEM. SI B11 11 15 January 2016 Engine Technical Service This Service Information bulletin supersedes SI 11 11 15 dated August 2015. The Service Engine Soon light is on with corresponding fault codes in the DME for the engine thermostat.
B1111172018-12-03. Service bulletin. ENGINE. ?ENGINE LEAK DIAGNOSIS ON TURBOCHARGED V8 ENGINES. When diagnosing an engine oil leak or a coolant leak on turbocharged V8 engines it is necessary to use a borescope to identify if the source of the leak is from under the turbochargers. Engine oil or coolant leaking from the bell housing area or the front timing chain cover area may be caused by the turbocharger itself, a turbocharger oil/coolant feed line or turbocharger oil/coolant return line. Do not remove the transmission and do not dissemble the engine before performing this inspection. If necessary, use engine oil leakage detection dye.
B1101132018-11-26. Service bulletin. ENGINE. N63 AND N63T ENGINE: ENGINE OIL CONSUMPTION, ENGINE OIL TOP-UPS AND REFILL CAPACITY. Customers with one of the vehicles above may complain that the engine's oil consumption is "too high," resulting in engine oil top-ups and workshop visits to address the issue before the vehicle displays an engine oil service as being "due." When the vehicle's engine oil drops to the minimum level, a message will display in the vehicle advising the driver to "add 1 quart of engine oil." After topping up and continued operation, the "add engine oil" message may display again before an engine oil service is required and performed. CAUSE Engines that are fitted with a turbocharger, as part of their normal operation, will consume engine oil at a higher rate than a naturally aspirated engine (non-turbocharged engine). In this case, a "turbocharged" engine could require topping up of the engine oil more frequently.
B1609182018-11-26. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:DIESEL. SCR SYSTEM FAULT 805256 STORED IN VERY COLD WEATHER. After the vehicle is exposed to prolonged temperatures under -9°C (15.8°F) and is then driven a long distance when temperatures are above -9°C (15.8°F), the check engine light may be illuminated. The following fault may be stored in the Digital Diesel Electronics (DDE) 805256 - Active tank filling level sensor, signal: echo fault In low temperature under -9°C (15.8°F) a layer of ice may form in the active tank. This can result in an incorrect level measurement after the vehicle is driven.
1305142018-11-26. 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.

In addition, a Check Control message of "Incorrect diesel exhaust fluid" may be displayed with "no start scenario countdown" active. This would cause any of the following additional faults to be stored, depending on the SCR system status at the time. 2C4E00 - SCR system: System error and poor urea/water mixture quality detected 26FD00 - Reducing agent metering, long-term adaptation: Adaptation value too high 29FB00 - SCR system, warning and deactivation scenario: Warning level 1 29FC00 - SCR system, warning and deactivation scenario: Warning level 2 CAUSE Unfavorable DDE software

1303142018-11-13. 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
1304132018-11-13. Service bulletin. ENGINE. N55 Engine: Erroneous Service Engine Soon Lamp Illuminated with Mixture Faults Stored in the DME. INFORMATION There is an error in the current version of ETK regarding N55 fuel injector replacement part numbers and production dates. Installing the incorrect injector part number can lead to an erroneous Service Engine Soon lamp illumination and various mixture faults stored in the DME. The vehicle may also exhibit rough running at idle and while driving. F07 and F10: P/N 13 64 7 639 994 is for all vehicles produced from 7/2014 P/N 13 64 7 597 870 is for all vehicles produced from 1/2011 to 7/2014 P/N 13 53 7 568 607 is for all vehicles produced to 1/2011 F06, F12 and F13: P/N 13 64 7 597 870 is for all vehicles produced from 1/2011 P/N 13 53 7 568 607 is for all vehicles produced to 1/2011 Until further notice, it is good practice to verify that the injector part number being removed from the engine matches the new injector part number. Always review the vehicle history to identify if the injectors have already been replaced. When the ETK data is corrected, a notification will be distributed. WARRANTY INFORMATION Not applicable.
