When Do Mercedes-Benz Fuel Injectors Need to Be Replaced?

Modern internal combustion engines are fitted with fuel injectors. They're used to control and atomise the fuel that goes into Mercedes-Benz engines. Fuel injectors have a valve that opens and closes, spraying a fine mist of fuel through a nozzle each time they open, this fuel then mixes with air which creates the required air-fuel mixture required for optimal engine combustion.

The injector open and close cycle repeats every engine revolution and in a majority of vehicles, there will be one injector per cylinder.

As you can imagine if one or more fuel injectors aren't spraying the correct amount of fuel it can have long term damaging effects on Mercedes-Benz engines and you could be in for a rough ride.

Fuel system contaminants can pass through Mercedes-Benz fuel injectors and cause build-up or rust. This may cause the injector nozzle to get stuck open or closed and cause leakage.

It's important to keep Mercedes-Benz fuel systems as clean as possible. If you notice a problem early enough the fuel injectors might be able to be salvaged, cleaned up, repaired and reused however sometimes they have reached the end of life and there's no option but to replace them.

When a fuel injector fails you may notice your Mercedes-Benz is idling roughly, misfiring, increased fuel consumption, the car has difficulty starting, engine splutter and accelerator hesitation.

When one or more injectors fail it affects the fuel for the engine to run efficiently. Without the correct air-fuel supply you are sure to notice a problem and when you do AutoGuru has you covered with experts available to replace that dodgy fuel injector.
