The fuel your BMW runs on contains a few contaminants; its production process can't get rid of them all. They can be trapped, though. Your factory fuel filter does that job, and before any muck can accumulate inside your engine. If the filter gets congested or degrades because of age, though, your fuel system can start to have trouble moving gas, and that means engine problems. Luckily, you'll know what's going on well before that happens.
What Are the Signs of a Bad Fuel Filter?
There are several, and they go beyond a Check Engine light. For example, your BMW might start roughly or shudder while idling. Moreover, its engine could lag when you press the gas pedal. Misfires and stall-outs could also happen, that is, if you can start your BMW at all. Complete engine failure, however, means fuel filter failure is probable. To get a better idea of what's happening, do an inspection. If it turns out your fuel filter has problems, your best bet is a replacement: put in a new genuine OEM one. BMW makes its fuel filters to fit its models specifically, and you can buy one online right from our auto parts catalog. Order now and tackle your next project in no time.
