BMW 750Li engine failure due to hydrolocking from injector failure, resulting in bent rod and ongoing issues on BMW 750Li

Some BMW 750Li owners report experiencing various engine problems, including performance issues such as oil leaks, fuel pump failures, overheating from coolant leaks, rough idling, and stalling. Many have noted that oil leaks often originate from the valve cover gaskets or oil filter housing. Additionally, common mechanical and electrical problems reported include faulty fuel pumps, failing alternators, glitchy iDrive electronics, and sagging air suspension. Furthermore, some owners have encountered issues related to hydrolocking due to faulty fuel injectors, prompting BMW to update the injectors to "index 11" to mitigate problems like bent and broken connecting rods. It is crucial for BMW 750Li owners to remain vigilant about these issues and address any warning signs promptly to prevent potential engine failures.
