B1116142018-11-13. 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. AFFECTED VEHICLES This Service Action applies to E70, E71, E72, F01, F02, F04, F07, F10, F12, and F13 vehicles with the N63 engines corresponding to the production dates listed above. First check if a Service Action label with a code number 728 is already attached to the B-pillar. If a code number 728 has already been punched out, the Campaign has already been performed and no further action is necessary. Eligible vehicles will show the following Service Action-related Campaign Code: 00 13 48 02 00 If the vehicle already has a label from a previous Service Action/Recall Campaign, affix the new label next to the old one. Do not affix one label on top of another one, because a number from an underlying label could appear in the punched-out hole of the new label."
