M1104132018-11-13. Service bulletin. ENGINE. Service Action: N14 Engine Check Timing Chain Tensioner and Timing Chain. The timing chain tensioner applies pre-tension to the timing chain guide rail mechanism. In some cases, the tensioner spring force may be too low. Depending on the severity of the wear, it may lead to a rattling noise when starting the engine cold or when the engine is idling. CAUSE The timing chain tensioner internal tolerances are not consistent.
M1101122018-11-13. Service bulletin. ENGINE; ELECTRICAL SYSTEM. "N16 and N18 Engine Oil Leak. The customer states that a small engine oil leak can be seen from the underside of the engine. CAUSE The internal sealing of the oil pump volume control solenoid valve is compromised, allowing engine oil to leak from the oil pump volume control solenoid. DIAGNOSTIC Below is the procedure for identifying how far the engine oil has migrated inside the engine electrical harness, when this issue occurs, if at all. The procedure must be followed very carefully so that the proper repair is identified. 1. Disconnect the oil pump volume control solenoid valve electrical connection per Repair Instructions 11 41 519 ""Removing and installing or replacing the solenoid valve (engine oil pump)."" Inspect the electrical connector; if no engine oil is found inside the electrical connector, perform the oil pump volume control valve repair procedure. If engine oil is found inside the electrical connector, proceed to diagnostic procedure step 2. 2. Remove the cover from the DME and remove all three electrical connectors from the DME. Inspect the connectors for traces of engine oil. If no engine oil is found, perform the oil pump volume control valve repair procedure and replace the engine section of the wire harness. Refer to EPC for the additional part number. If engine oil is found in the DME connector, proceed to step 3. 3. If engine oil is found in the DME electrical connector, perform the oil pump volume control valve repair procedure, replace the engine section of the wire harness and replace the DME. Refer to EPC for the additional part numbers. Do not remove the engine oil pan. Do not replace the oil pump volume control valve. Do not replace engine oil pump. OIL PUMP VOLUME CONTROL VALVE REPAIR"
