BMWs are designed with efficiency, high-performance, and impressive power in mind to help satisfy their fan base’s cravings for more driving satisfaction. Just like all other vehicle brands, however, BMWs have a list of specific issues their various models and series commonly encounter. One such issue in certain vehicles produced in earlier years is related to the high-pressure fuel pump. Some drivers are just now experiencing fuel pump failure, and some have dealt with the issue for years. In this article, we’ll go over some basic information about your BMW’s fuel pump, including it’s main purpose, how to spot malfunction, and what you can do moving forward to best protect your BMW from further failures.

Unfortunately, these fuel pumps are prone to failure and malfunction rather quickly into the life of the vehicle.
