6 Reasons Your Mini Cooper’s Check Engine Light is On

Mini Cooper's check engine lightThe dreaded check engine light is definitely not something you want to see when out cruising in your Mini Cooper. But, although it can be frustrating, your Mini Cooper’s check engine light can end up saving you a lot of time, expense, and hassle, as long as you don’t ignore it.

While your check engine light may come on for a multitude of reasons, often it is merely detecting some smaller problems that have the potential to cause more major issues if left alone. So by simply paying attention to this light right away, you may be saving yourself a lot of trouble down the line.

Here are the top six reasons your Mini Cooper’s check engine light may be on:

1. Loose Gas Cap

This is definitely the issue everyone hopes they have. Basically, when the gas cap is not screwed on tightly enough, it triggers your Mini Cooper’s check engine light. Simply screw it on more securely, and this will fix the issue.

2. Faulty Oxygen Sensors

Part of the exhaust system, the oxygen sensor regulates the oxygen to gas ratio. When this part is not working correctly, your engine may start running irregularly. Other symptoms, besides the check engine light, include poor gas mileage and rough or irregular engine idle. Getting this part replaced as soon as possible will correct the issue, and prevent any further damage from occuring.

3. Defective Catalytic Converter

This problem usually only happens after something else in the vehicle has broken, causing exhaust system problems. This is one of the most expensive reasons your Mini Cooper’s check engine light might be on, and usually can be avoided by keeping up with regular maintenance and addressing any minor issues quickly, before they get out of hand.

4. Worn Out Spark Plugs

Another part that should be checked during your regular maintenance, worn out spark plugs can cause problems with starting your car, engine misfires, and can even eat away at your fuel.

5. Cracked or Loose Hoses

Cracked or loose vacuum hoses can trigger your check engine light because the evaporating fuel will not reach its vented destination. 

6. Defective Mass Air Flow Sensor

This sensor is in front of the intake, and monitors incoming air in order to supply the right amount of fuel. Similar to the oxygen sensors, if this part is not working correctly it can have a drastic effect on your gas mileage.

The best way to prevent your engine light coming on, is to follow your Mini Cooper’s recommended maintenance schedule. But even that is not always enough. Keeping an eye out for other, major symptoms can help you determine the urgency of your problem. But when in doubt, contact an expert who can do a more thorough inspection and diagnosis of your Mini Cooper’s engine.
