BMW vehicles are popular for their excellent performance, high reliability, and speed. However, what is the use of these qualities if the vehicle fails to start? This is a common problem that BMW owners may face when the car’s ignition system is faulty.
The ignition module is a part of the ignition system responsible for generating the spark that ignites the engine to start. An ignition module failure can lead to several car problems; hence, it is important to understand the signs of a fault and what to do in that case.
The ignition system comprises several components, such as the ignition coil, spark plugs, switch, battery, and control module. The main purpose of this system is to produce the spark that heats the air-fuel mixture, which then generates the energy needed for the engine to run.
The main role of the ignition module is to work with the Engine Control Unit (ECU) to optimize the timing of the ignition (when the spark plugs generate the spark) for better engine efficiency. However, this module could fail for various reasons, which can affect how the engine generates its power to function.
Some of the reasons for a car’s ignition module failure are:
One of the common causes of failure in a car’s components is wear and tear. It is expected that as your car ages and is used, some of its parts will begin to wear out and fail, and this can happen with the ignition module.
The ignition system is similar to the electrical system in that moisture can cause serious damage. If your car’s system is exposed to water, either from rainfall or during cleaning, some of its parts (such as electrical connections) may begin to experience corrosion and, over time, could fail to function.
While the ignition module helps to keep the engine working, the engine could be the reason for its failure. If this module is exposed to the engine’s high heat, it could overheat and eventually get faulty.
You must first recognize the issue before you can fix any issue with your car. Hence, here are some tips to help you identify a faulty ignition module in your car:
The simplest way to identify if your car’s ignition module is damaged is to perform an inspection. You can start with a visual inspection by looking for any physical sign pointing to damage to the module or its system. Look for damage, corrosion, or loose connections.
Aside from visual signs, some other signs that could further confirm your suspicion of an ignition module fault are difficulty starting the car, engine stalling, loss of power, and an illuminated “check engine” light.
Another simple way to diagnose if the problem with your car is due to a faulty ignition module is to use an OBD-II scanner to check for trouble codes. You can then look up the code using your car’s service manual to correctly determine the problem with your car.
However, the best way to diagnose an issue with your car is to let a professional look at it. There are many reasons a car could be showing a particular sign; however, a qualified mechanic can easily identify the issue and find a solution. In most cases, an ignition module problem will require a replacement. However, you should allow your trusted mechanic to determine the next step.
Getting your car checked and assessed by a professional helps to save you from more complications and further damage. A professional can also use various tools and equipment to correctly diagnose the problem with your car. Remember that a wrong diagnosis can cause even more problems for your car.
