It can be quite unnerving to hear what some would call a pinging or rattling sound in the engine of your BMW. These sounds could be the result of a malfunction in your car. Any BMW owner knows not to ignore these sounds, as they could be telling of a bigger problem in the engine of your vehicle.

We encourage you to pay close attention to any unusual noises in your car engine and bring it to our auto mechanics as soon as you suspect a problem. There could be multiple reasons for the noise you hear in your engine, but for accurate diagnostics and repair, we suggest that you visit our nearest auto repair shop. Let’s take a closer look at the possible problems.

Causes for a Noisy BMW Engine

Gas leaks

Your BMW runs the exhaust of your car through an attachment to the engine. If a leak occurs in the manifold, it results in an expulsion of gases. These could sometimes lead to the noise you hear in your engine.

Low steering fluid

A bad steering pump and steering fluid could lead to bigger problems for your BMW. Low-power steering fluid could cause whirring sounds in your engine.

Drive belt or pulley bearing

Often when there is a problem with your drive belt or pulley bearing, the engine will make a loud squeaking sound when accelerating. This sound will likely stop when the engine warms up but it shouldn’t be ignored. Your BMW should be towed to our repair shop for an inspection.

Loose lifter

A loose lifter often results in a necessary repair. A loose lifter is a mechanical problem and is often accompanied by a ticking sound in the front of your car. When the lifter in your BMW cones loses, it will continually tap against the camshaft and this friction produces the ticking sound you often hear.

Alternator Bearings

Another common cause of noise in your BMW engine is a faulty alternator bearing. These bearings work together with the rotor to perform major electrical functions in your vehicle and to recharge its battery. It is important to get your BMW checked immediately if you hear the rattling in order to prevent extensive damage.


When your vehicle overheats over a long period of time, it causes parts to break down and causes extensive damage. Overheating can cause your crankshaft and bearing to seize as well as damage the engine in the long run.

How to Fix the Noise in your BMW

Paying regular attention to the parts of your BMW is absolutely necessary. It’s only with constant observation that you can detect early enough the unusual noises in your vehicle. As mentioned earlier, sometimes the noises in the car are part of the regular functioning of the vehicle. Hence to prevent the problems in the vehicle from getting worse, you should take note of them early enough.

This aside, it is important to change your engine oil regularly. It is advisable to regularly clean out your oil tank and change your engine oil to prevent contamination. If you are unable to do this yourself, you should conduct well-trained personnel to do this for you.

Also, it is pertinent to take your vehicle to a reputable auto repair shop for repairs. This should be done immediately when you notice the damage in order to prevent it from escalating. Leaving the damage unrepaired could cause it to damage other parts of the vehicle, which would ultimately result in more expenses for repair.
