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.
