FAQ: Colored Exhaust Smoke


FAQ: Colored Exhaust SmokeWhen it comes to detecting problems with BMWs it is important to use your senses. There are numerous ways to determine that something is amiss with your car or SUV, including smells, vibrations and of course visual queues. You should always be on the lookout for trouble, as the sooner it is spotted, the faster it can be repaired, thus minimizing the services and time required to get your Bimmer back on the road. One visual queue that you should be very aware of is colored exhaust smoke. What does it mean? Read on.

What does it mean if my BMW produces colored exhaust smoke?

A vehicle that emitting colorful exhaust is more than likely suffering from some sort of internal engine problem. The issue is that something is being burnt up in the engine that is resulting in the exhaust changing from a normal clear, to a puffy colored emission. Depending on the color of the smoke you can generally tell what sort of problem is occurring. Always get to an auto repair shop as soon as you notice the increased emissions to be sure that you're not left with any more damage than necessary.

What does blue exhaust smoke mean?

If you notice that your vehicle is producing blue exhaust smoke you're going to want to head to a mechanic right away, as this could be a very serious problem. The issue is that engine oil is being burnt up in the combustion chamber. This puts your motor at risk of oil starvation which results in harsh metal on metal contact amongst its moving parts. Without proper and quick service extensive engine repair could be necessary.

What does black exhaust smoke indicate?

A vehicle that is emitting black exhaust smoke is suffering from a problem called running rich. This means that excessive gasoline is being burnt, which can have a few negative effects on the motor, including detonation and of course highly reduced fuel economy. There are a few issues that could cause this, including leaking fuel injectors or even something as simple as a clogged air filter.

What problem does my BMW have if it has white exhaust smoke?

Puffy white exhaust smoke indicates that coolant is being burnt up in the engine. This puts your car at risk of overheating, which could lead to numerous problems, including a blown head gasket or even a cracked engine block.
