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.
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.
1114142018-11-26. Service bulletin. ENGINE. Engine Damage Due to Debris in Oil Passages. After performing extensive engine repairs (e.g., cylinder head removal), the engine begins to knock and may lose power. Debris has entered the engine oiling passages during cleaning of the engine block and cylinder head mating surfaces during engine repair.
