1214132018-12-03. Service bulletin. ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING. PERFORM THE PROCEDURE OUTLINED IN THIS SERVICE INFORMATION ON ALL AFFECTED VEHICLES BEFORE CUSTOMER DELIVERY OR THE NEXT TIME THEY ARE IN THE SHOP FOR MAINTENANCE OR REPAIRS. BMW centers must ensure recalls are completed after having been notified by BMW of North America, LLC (BMWNA) that a safety-related defect or noncompliance exists in any motor vehicle or item of replacement equipment in the center's possession at the time of notification. In BMW NA's case, this notification would typically be made by the issuance of a recall notification in the form of a Service Information bulletin (SIB) or transmission of a Dealer Communication System (DCS) recall message. Under the National Traffic and Motor Vehicle Safety Act of 1966, as amended, if a recall campaign is announced by BMW NA, centers must ensure that all recalls on new vehicles and new items of replacement equipment are completed BEFORE delivery to the consumer. This means that centers may not legally deliver new motor vehicles or new items of replacement equipment to consumers with an open recall. The Safety Act also prohibits centers from selling or leasing the motor vehicle or item of replacement equipment, unless and until the open recall has been completed BEFORE delivery. This also pertains to vehicles in the Certified Pre-Owned program, and to items of replacement equipment. Finally, BMW centers should not sell or use parts that have been recalled by BMW NA. Please follow the specific instructions provided by BMW NA on the return or disposition of the parts. SUBJECT Voluntary Emissions Recall Campaign 13E-A01: Program Control Units (Tank Ventilation). Due an error in the DME (Digital Motor Electronics) software, the fuel tank ventilation system may not sufficiently purge the active carbon canister of accumulated fuel vapor under certain engine operating conditions.

1215132018-12-03. Service bulletin. ENGINE. N20 and N26 Engine: Various VANOS System Faults Stored in DME. The Service Engine Soon lamp is illuminated; Engine Malfunction warning is illuminated; and the vehicle has reduced power output. Various faults related to VANOS operation are stored in the DME. While performing the test plan, the results may appear to be inconclusive because the fault will not clear from DME Fault Memory. The ISTA/D diagnostic test plan does incorporate a VANOS bleed function, but it does not advise the technician to bleed the VANOS system after a VANOS or engine oil supply component replacement. CAUSE This is due to an error in the current level of ISTA/D. The error will be corrected with ISTA/D 2.41.0.
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.
B1108152018-12-03. Service bulletin. ENGINE. N63 and S63 Engine: Valve Seal Replacement.
