This led BMW to introduce a \"Customer Care Package,\" detailed in Technical Service Bulletin (TSB) B110614, to address the concerns reported by multiple owners and noted by the National Highway Traffic Safety Administration (NHTSA) under ID Number 11016414. A primary cause of the issue is accelerated timing chain wear. The N63 engine's design features timing chains that are prone to stretching prematurely. This stretching can disrupt the precise timing of the engine's valves, leading to a cascade of problems. As a consequence, owners have reported a variety of symptoms, including the illumination of the \"drivetrain malfunction\" warning light, noticeable engine noise, excessive vibration, and potentially catastrophic engine failure. The \"drivetrain malfunction\" message, in particular, is a frequently cited indicator of this underlying powertrain problem. To address these widely reported issues, the N63 Customer Care Package was implemented. This service bulletin instructs authorized BMW technicians to perform a series of diagnostic tests. The main objective is to detect if the timing chains have stretched beyond acceptable tolerances. If excessive wear is confirmed, the TSB provides a detailed procedure for the necessary repairs. This often involves replacing the timing chains and related components to restore proper engine function. Beyond the core timing chain replacement, the Customer Care Package also includes several proactive and preventative measures. Technicians are instructed to check and potentially replace other components, such as fuel injectors and boost solenoids, which may have been impacted or contributed to the engine's performance issues. Furthermore, the service includes reprogramming the vehicle's software","products":[{"type":"Vehicle","productYear":"2012","productMake":"BMW","productModel":"535I","manufacturer":"BMW of North America, LLC"}]}]}
