The average cost of a BMW 745i fuel injector is between $90.99 and $96.99.
The BMW 745i fuel injector is a component of the fuel system in the BMW 745i model. It is responsible for delivering the correct amount of fuel to the engine's combustion chambers for efficient combustion. The fuel injector atomizes the fuel and sprays it into the intake manifold or directly into the combustion chamber, depending on the specific engine design. This ensures proper fuel distribution and optimal performance of the engine.
Signs of Faulty or Worn BMW 745i Fuel Injector
There are several signs that can indicate faulty or worn out fuel injectors in a BMW 745i. These include:
- Engine misfires: If you experience frequent engine misfires or rough idling, it could be due to a faulty fuel injector. This occurs when the injector fails to deliver the proper amount of fuel to the engine's cylinders.
- Poor fuel efficiency: Failing fuel injectors may cause your vehicle to consume more fuel than usual. If you notice a significant decrease in fuel efficiency, it could be a sign that one or more fuel injectors are not functioning properly.
- Stalling or hesitation: Faulty fuel injectors can lead to engine hesitation or stalling when accelerating. This occurs when the injector does not open and close correctly, causing a disruption in the fuel supply to the engine.
- Strong odor of gasoline: If you detect a strong smell of gasoline inside or around your vehicle, it may indicate a leaking fuel injector. Leaks can occur when the injector's seal or nozzle becomes damaged or worn, resulting in fuel seepage.
- Decreased engine performance: Worn or clogged fuel injectors can impact the overall performance of your BMW 745i. You may experience reduced power, sluggish acceleration, or a lack of responsiveness from the engine.
- Increased exhaust emissions: A faulty fuel injector can affect the air-fuel mixture going into the engine, leading to higher levels of unburned fuel being released through the exhaust system. As a result, you may notice black smoke or a strong smell of gasoline coming from the tailpipe.
If you suspect any of these issues with your BMW 745i, it is advisable to have a professional mechanic diagnose and repair the fuel injector problem to ensure optimal performance and fuel efficiency.
Replacing BMW 745i Fuel Injectors
Replacing the fuel injector in a BMW 745i involves several steps. Here's a general outline of the procedure:
- Ensure safety: Park the vehicle in a well-ventilated area, turn off the engine, and disconnect the battery to prevent any accidental starts.
- Access the fuel injectors: Remove the engine cover or any components obstructing access to the fuel injectors. It may involve loosening or removing other parts, such as air intake components or the fuel rail.
- Relieve fuel system pressure: Locate the fuel pressure relief valve, typically found on the fuel rail, and carefully relieve the system pressure by following the manufacturer's instructions. This step is crucial for safety purposes.
- Disconnect electrical connections: Detach the electrical connectors from the fuel injectors. These connectors are usually secured with clips or fasteners that need to be gently released.
- Remove the fuel rail: Unbolt the fuel rail from the engine block carefully. Depending on the specific design, it might be necessary to remove additional components, such as sensors or brackets, to access and remove the rail.
- Remove the old injector(s): Each fuel injector is secured to the fuel rail and intake manifold with mounting hardware. Carefully detach the injector by removing the retaining clip or bolts and pulling it straight out. Take note of the injector orientation and position to ensure correct installation later.
- Clean and inspect: Before installing the new injector, thoroughly clean the injector ports on both the fuel rail and intake manifold. Inspect the surrounding area for any signs of damage or debris that could impact the new injector's performance.
- Install the new injector(s): Apply a thin layer of fuel injector O-ring lubricant to the new injector's O-rings. Insert the injector into the corresponding port on the intake manifold and secure it with the retaining clip or bolts. Ensure it is properly seated and aligned.
- Reassemble components: Reinstall the fuel rail, ensuring it sits flush with the intake manifold. Secure it with the appropriate bolts or clips. Reconnect the electrical connectors to the fuel injectors and ensure they are properly attached.
- Test for leaks: Before starting the engine, perform a visual inspection of all connections and double-check that everything is secure. Once satisfied, reconnect the battery, turn on the ignition without starting the engine, and check for any fuel leaks.
- Test drive: Start the engine and let it run for a few minutes to ensure proper functioning of the new fuel injector(s). Take the vehicle for a test drive to monitor its performance, paying attention to any abnormal symptoms or issues.
It's important to note that the specific steps and procedures may vary depending on the model year of the BMW 745i and other factors. It is always recommended to consult the vehicle's repair manual or seek professional assistance if you are unfamiliar or uncomfortable with performing this task.
Typical Lifespan of BMW 745i Fuel Injectors

Generally, a fuel injector can last anywhere between 50,000 to 100,000 miles or more. It is always recommended to follow the manufacturer's recommended maintenance schedule and address any fuel system issues promptly to maximize the lifespan of the fuel injector.
