The average price of a BMW 745i ignition coil is between $20.59 and $73.99.
The BMW 745i ignition coil is a crucial component of the vehicle's ignition system. It plays a key role in generating and supplying high voltage electrical pulses to the spark plugs, which ignite the fuel-air mixture in the engine cylinders. The ignition coil converts the low voltage from the battery into the high voltage needed for the spark plugs to create a spark. This spark then ignites the air-fuel mixture, ensuring the proper functioning of the combustion process and ultimately powering the vehicle.
Signs of Faulty or Worn BMW 745i Ignition Coil
The most common signs of faulty or worn out BMW 745i ignition coil are:
- Engine misfires: One of the primary indicators is when the engine misfires or runs rough, causing it to shake or vibrate excessively. This occurs due to the ignition coil not providing a consistent spark to the spark plugs.
- Decreased fuel efficiency: A faulty ignition coil can lead to incomplete combustion, resulting in decreased fuel efficiency. You may notice a drop in your vehicle's mileage, requiring more frequent refueling.
- Difficulty starting the engine: If the ignition coil is worn out, you might experience difficulty starting the engine. It may take multiple attempts or longer cranking times before the engine starts.
- Stalling: Another common sign is engine stalling, where the vehicle suddenly shuts off while driving or at idle. This is often caused by a weak or inconsistent spark from the faulty ignition coil.
- Rough idling: Worn out ignition coils can cause the engine to run erratically during idle, resulting in a rough or uneven idle. You may notice the RPM fluctuating or a noticeable vibration when the car is stationary.
- Poor acceleration: When the ignition coil is faulty, the engine may struggle to accelerate smoothly. You might experience a lack of power or hesitation when pressing the gas pedal.
- Increased emissions: A failing ignition coil can lead to an increase in harmful emissions. If you notice black smoke coming from the exhaust or fail an emissions test, it could be due to a faulty ignition coil.
- Illuminated check engine light: In many cases, a faulty ignition coil will trigger the check engine light on your dashboard. It is advisable to have the vehicle's onboard diagnostics system scanned to identify the specific fault code related to the ignition system.
If you suspect that your BMW 745i has a faulty ignition coil, it is recommended to have it inspected and replaced by a qualified mechanic or BMW dealership. They can accurately diagnose the issue and ensure proper replacement with genuine parts.
