1106142018-11-13. Service bulletin. ENGINE; EQUIPMENT; EQUIPMENT:ELECTRICAL. "This Service Information bulletin and attachment supersedes SI B11 06 14 dated January 2015. designates changes to this revision SUBJECT N63 Engine: Customer Care Package. INFORMATION This bulletin outlines the Customer Care Package program that has been designed exclusively for BMW vehicles with the N63 engine. Vehicles with the N63 high performance engine are engineered with EfficientDynamics that provides fuel economy without compromising on its ""class leading"" power and performance. To ensure these engines keep delivering the ultimate performance, we have designed this Care Package that includes a 6 point check, and if necessary, the replacement of one or more of the following powertrain components: z Hot-Film Air Mass Sensors z PIEZO High Pressure Fuel Injectors z Engine Vacuum Pump z Fuel System Low Pressure Sensor/Feed Line z Fresh Air Intake Turbo Seals z Crankcase Ventilation Lines (Hoses) This engine care package also includes a multi-point inspection of the vehicle, including tire pressures, fluid levels, safety and convenience features. The N63CCP is NOT a mandatory Technical Campaign or Recall (per the authorities). It should only be completed based on parts availability, workshop capacity, and the customer's schedule. Complete all other applicable open Campaigns per the DCS Warranty inquiry and the Key Reader. Perform all recommended, due or qualifying ""time-based"" maintenance service task items as directed by the Key Reader/ISPA Light application. When eligible, also perform the procedure described in SI B61 30 14: 12-Volt Battery Replacement together with performing the N63 Customer Care Package. After completing all the necessary repairs, the vehicle needs to be road tested for 30 minutes to assure the highest standard of performed repairs (Please see ""Warranty Information"" section below)."
B1112162018-11-13. Service bulletin. ENGINE AND ENGINE COOLING. SERVICE ACTION: N63T ENGINE - CHECK AND REPLACE THE CRANKCASE VENTILATION HOSES. The crankcase ventilation hoses may become brittle and break when they come in contact with hot engine components. One or more of the crankcase ventilation hoses are not FPM rubber material. The FPM rubber material is engine heat resistant. Or The plastic coggurated hoses are not fitted with the self-locking spacers. The self-locking spacers maintain an air gap between the hoses and the hot engine components.
B1116142018-11-05. Service bulletin. ENGINE. "This bulletin outlines the procedure for checking the engine timing chains for wear, and should be completed in conjunction with SI B11 06 14, ""N63 Customer Care Package."" The N63CCP and N63 Engine Check the Timing Chain are NOT mandatory Technical Campaigns or Recalls. They should be completed only based on parts availability, workshop capacity, and the customer's schedule. Performing the test plans identified in the procedure below will detect wear at an early stage and, if necessary, provide a repair solution. To avoid future valvetrain wear, the vehicle must be reprogrammed and a shorter oil service interval must be retrofitted via ISTA/P. Finally, drain and replace the engine's oil and filter. After completing all necessary repairs included in the N63 Customer Care Package and the Timing Chain Check, the vehicle must be test driven for up to 30 minutes to ensure that the repairs were performed to the highest standard."
