Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
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.
