INFORMATION
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.
T
hey 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.
