3 Common Causes of Major Engine Problems


Your BMW's engine is subject to operating in very harsh conditions. But, so long as you provide it with proper and routine factory maintenance there is a good chance that it will last in excess of 200,000 miles without the need for major repair, regardless of what you drive. However, there is always the chance of the lemon in the bunch. More often than not though engine failure can be attributed to neglecting the BMW services that it requires. If you've recently suffered some sort of major engine trouble it is most likely due to one of the following reasons.

Overheating Issues

Overheating is the name of the event that occurs when the engine heats up too much, which could lead to the failure of multiple parts. Overheating is usually attributed to a coolant leak of some sort, but other causes of this could include a faulty water pump, a bad electric cooling fan, or a failed thermostat. Be sure to have your cooling system serviced as according to your vehicle's service schedule. This allows a mechanic to ensure the system is in a healthy condition and can properly keep the engine cool.

Improper Engine Lubrication

Perhaps the most common cause of major engine damage is not making sure the engine has the oil it needs. Regardless as to whether or not you give your vehicle regular oil changes, it is necessary to check other parts for potential problems or oil leaks or you could end up needing an engine replacement. Aside from a vehicle that burns and/or leaks oil, the usual suspects when it comes to oil starvation are a faulty oil pump, high mileage, or simply failing to conduct oil changes as frequently as necessary.


Abnormal combustion within the engine is known as detonation. This event produces excessive heat and pressure inside the combustion chamber which can lead to numerous problems. Detonation is essentially fuel spontaneously combusting at improper times. This leads to the production of the heat, and often times a knocking noise. The most common reason for this to happen is the loss or failure of the exhaust gas recirculation system. This system ensures the correct air/fuel mixture when the engine is running. However it may also be caused by incorrect ignition timing, dirty spark plugs or polluted fuel.

It is important to keep up with regular auto maintenance to ensure that your engine and the rest of your vehicle stays healthy. Always pay attention to the signs your vehicle is giving you that there may be some sort of trouble brewing.
