Santa Rosa, CA – Find Out Why Carbon Builds Up Near the Spark Plugs of Your BMW

Are you worried about carbon build up around the spark plugs of your BMW? Study the main causes of this build-up and how it can be prevented.

Owning a BMW is a privilege not everyone can afford. Part of owning this captivating vehicle is to stay informed of any issues that may arise over its useful life and addressing it at your earliest.

One such issue is a faulty spark plug, which can occur for a variety of reasons. It makes sense to know why a spark plug fails so you can immediately contact support when you suspect any issues. A common cause for faulty spark plugs is the build-up of carbon around it.

This carbon build-up is black substance with a light texture that results in a rich fuel mixture or a weak spark. Carbon build often leads to a problem known as carbon fouling, a situation when the spark plug’s insulator nose is covered in debris.

Not addressing carbon fouling can lead to even more complicated issues. The most effective approach is to know the common causes of carbon buildup around spark plugs and nip them in the bud.

BMW Stays Motionless for Extended Periods

When your BMW stays motionless for longer, the spark plugs won’t heat up during those times, and thus, won’t burn any build up of carbon or debris around them. If you don’t plan to drive any time soon, simply turn off your vehicle during the time your vehicle stays motionless.

Stop-And-Go Traffic

Repeated stopping and moving of your BMW not only hurts the vehicle’s mileage but may also result in carbon fouling. A traffic situation like this leads to continuous fluctuation in pressure as well as in the flow of gases and/or fluids through the engine.

To prevent the problem from getting worse, keep an eye on your spark plugs. If you’re often faced with such driving conditions, keep cleaning the spark plugs before you drive off.

Rich Fuel Mixture

If the air-to-fuel ratio in your engine is not balanced in your engine, the problem of a rich fuel mixture becomes inevitable. This is a situation when the quantity of fuel exceeds the amount of air by a great deal. This can occur because of oxygen sensors or a malfunctioning fuel injector. Rich fuel mixture can also cause carbon buildup.
