Signs of Ignition Coil Failure in Your Mini

MINI Ignition Coil

Mini are compact and durable vehicles that have been in the automotive industry for decades. These vehicles are known for their unique design and engine efficiency. Your Mini will continue to serve you effectively as long as you maintain it in the best way possible. Failure to do that might lead to different faults in your Mini.

Unfortunately, even with regular maintenance, your Mini parts can develop faults as a result of normal wear and tear. One of the parts of your Mini that can fail is the ignition coil. The ignition coil provides electrical power in modern cars. As a result, your engine won’t function properly if your ignition coil is damaged. And worst of all, it might stop entirely. As a result, understanding the signs of a damaged ignition coil and how to avoid them is crucial.

What is an ignition coil, and what does it do?

When you attempt to start your car, the current generated by the battery is nowhere near sufficient to start the operation. The ignition coil enters the picture at this point.

The term “compact electrical transformer” is frequently used to describe ignition coils. These gadgets’ primary function is to transform the 12-volt current that typically flows from the car battery into the much greater voltage required to light the gasoline and start the engine. Your car’s spark plugs each have their ignition coil. Some are just placed on top of the spark plug without using any wires at all, while some ignition coils are coupled to the spark plugs by cables. For the plugs to produce an electric spark powerful enough to ignite the fuel, between 15,000 and 20,000 volts of electricity are needed. You may experience poor fuel economy or an engine misfire if your ignition coil fails.

Symptoms Your Ignition Coil Needs Repair

  • If your check engine light is on: The check engine light turning on is most likely one of the symptoms if your MINI’s ignition coil has failed. The most frequent error code you’ll see when using an OBD2 scanner is P0351 (Ignition Coil – Primary/Secondary Circuit Malfunction).
  • You Can’t Start Your Car: As mentioned, broken ignition coils prevent your automobile from starting. Your engine won’t start if the air and gasoline combination isn’t ignited below the hood, and your car can get stuck where you left it. Verify that your battery is still fully charged. If so, it can indicate that the ignition coil is failing to convert the charge.
  • Backfiring: One of the initial warning indications of a failing ignition coil is a backfiring engine, which can frequently occur even in the early phases of coil failure. If any unburned fuel in the engine’s combustion cylinders escapes through the exhaust pipe, backfiring may result. Typically, a backfiring engine may make a loud cracking noise or release some dark smoke. The smell of petrol in the smoke can also identify a faulty ignition coil.
  • Engine misfiring is another typical symptom of defective ignition coils. When starting your car, odd coughing or sputtering noises are frequently signs of misfiring. A malfunctioning ignition coil might also make your automobile vibrate a lot while it is idle.
  • Poor gas mileage: If you observe your MINI’s fuel economy declining over time, this might indicate many issues, including the failure of your ignition coils. To identify the problem before it becomes more expensive or perhaps dangerous, you should think about taking your car to a repair facility as soon as possible if it has poor fuel efficiency.
