Based on industry averages you can expect to pay between $53.99 and $333.99 for a Mercedes E550 fuel injector.
A Mercedes E550 fuel injector is a crucial component of the vehicle's fuel system. It's essentially a small electrically operated valve that directs a precise amount of fuel into the car's engine at exactly the right moment, helping to ensure the engine runs smoothly and efficiently.
This component relies on calculated input from the vehicle's computer to function optimally, and it plays a significant role in the overall performance and fuel efficiency of the car. Any problems with a fuel injector can lead to serious engine issues, so it should be maintained properly and replaced if necessary.
Signs of Faulty or Worn Mercedes E550 Fuel Injector
- Engine Misfire: This happens when fuel isn't properly distributed to the cylinders. A misfiring engine can cause vibrations, decreased performance, and can also be harmful for the engine in the long term.
- Rough Idling: If your Mercedes E550 is running rough or irregularly at idle, it might be due to issues with the fuel injectors.
- Decreased Fuel Economy: If you notice that your car is consuming more fuel than usual, a faulty fuel injector could be to blame.
- Check Engine Light: Your vehicle's onboard diagnostics system may detect an issue with the fuel injectors and trigger the check engine light.
- Fuel Leaks: A worn out fuel injector can have internal or external leaks which can cause fuel smell or visible leaks under the vehicle.
- Poor Performance: If the fuel injection system isn't working as it should, the overall performance of the vehicle will suffer. You may experience power loss, hesitation, or difficulty starting the car.
- Engine Stalls or Vibrations: Faulty fuel injectors may cause the engine to stall while driving or excessive engine vibrations due to improper fuel distribution.
- Smelly Exhaust: If the fuel injector is faulty, it can cause a rich fuel mixture leading to a strong smell from the exhaust. It can also cause black smoke due to incomplete combustion.
- Difficulty Starting: If your car has trouble starting up, it might be due to a problem with the fuel injectors not providing sufficient fuel for ignition.
- Engine Knocking Noise: This is caused by the air/fuel mixture detonating in more than once place at a time. The extra explosions can cause a knocking noise, and can severely damage the engine over time if not addressed.
Replacing Mercedes E550 Fuel Injectors
- Park the vehicle in a safe and level location. Make sure the vehicle is turned off and has had time to cool down to prevent burns from hot parts.
- Open the hood and disconnect the battery. Usually, it's best to remove the negative cable first for safety reasons.
- Remove the engine cover by loosening the bolts or clips that keep it attached.
- Locate the fuel rail and release the pressure by using a fuel pressure gauge. Take caution as fuel may squirt out due to pressure.
- Disconnect the fuel lines running to the fuel rail. These could be held in place with quick-disconnect fittings, clamps, or bolts.
- Unbolt or unclip the fuel rail. You might need to gently wiggle or pry it free. Be careful not to damage the fuel injectors or rail.
- Carefully pull the faulty fuel injector out of the rail. A gentle twisting motion may help. Do not force the injector if it doesn't come out easily.
- Before installing the new injector, lubricate the O-rings with engine oil.
- Install the new injector into the rail, making sure it snaps into place securely.
- Reinstall the fuel rail, ensuring it fits snugly over the new injector(s). The bolts should be tightened to the manufacturer's specification.
- Reconnect the fuel lines.
- Replace the engine cover.
- Reconnect the battery, starting with the positive cable, then the negative.
- Start the vehicle to check if any leaks are present. If the engine runs smoothly and no fuel is leaking, you've successfully changed your fuel injector.
Typical Lifespan of Mercedes E550 Fuel Injectors
The lifespan of a fuel injector in a Mercedes E550, or indeed in any vehicle, varies greatly depending on factors such as the quality of fuel used and driving habits. However, under normal circumstances, one could expect a fuel injector to last between 80,000 and 150,000 miles. It's important to maintain your vehicle regularly and watch out for signs of a failing fuel injector, such as poor gas mileage, misfires, or a rough engine idle.
