Reasons Behind Your BMW’s Check Engine Light Activating

Reasons Behind Your BMW’s Check Engine Light Activating

All vehicles are incredibly complex machines, especially those which have been intelligently engineered and thoughtfully designed, such as BMW. Because of this, your car has a variety of systems in place to protect you and your car from the effects of severe part failure. One such system is the check engine warning light. Below, you can find out how the light works as well as the types of part failure which can cause it to illuminate.

What is the check engine light?

The Engine Management Light (EML) or check engine light is a warning indicator which is found on your BMW’s dashboard. It will illuminate when more severe issues are detected in your vehicle’s systems or parts which work with the engine and the connecting exhaust systems.

The engine management light connects directly to your BMW’s main computer, which is known as the ECU or Engine Control Unit. If the ECU detects an issue in one of the aforementioned systems, it will trigger the check engine light and send out an error code. This can be used to correctly diagnose and repair the problem.

How a driver should immediately respond to the EML depends on the severity of the issue. If the car still feels like its running fine, then lower your speed and drive it directly to a professional repair shop. However, if the EML lights up red or your car no longer feels safe, then pull over and call for a recovery vehicle to tow you to a repair shop.

Common Reasons Why the Check Engine Light may Illuminate

There are many reasons why this essential warning light may illuminate. Below, we have listed some of the most common reasons, how risky they are for your car, and how you should respond.

Vacuum Hose Leaks

Damage Level: Low
Response: Lower your speed and locate the nearest auto shop.

Vacuum hoses are needed to channel both fresh air as well as emissions around the engine to allow it to run correctly. They’re made of rubber and can be exposed to high temperatures inside the engine which can lead to them cracking or deteriorating over time. When this happens, the precise balance of gases can be thrown off-kilter, leading to the engine’s sensors reporting issues to the ECU.

Loose Filler Cap

Damage Level: Low
Response: Check the cap and replace as needed.

This issue is most commonly caused by drivers being distracted at the pumps and not correctly tightening their fuel cap. A loose cap allows extra air into the tank which distripts the pressure. This will cause one of the many sensors to detect an issue and inform the ECU. This is the most simple and most common cause for check engine light illumination and should always be ruled out first.

Fuel Pump Blockage

Damage Level: Medium
Response: Lower your speed and locate the nearest auto shop.

The fuel pump is what provides pressurized fuel to the fuel injectors. If the pump isn’t working correctly, then the fuel will not be able to be properly delivered to the engine, causing rough running. The engine light will be illuminated by the ECU and your BMW will likely be at an increased risk of misfires.

Soot on the Particulate Filter

Damage Level: High
What to do: Lower your speed and locate the nearest auto shop, or call for a tow.

The particulate filter is most commonly found in diesel models, but it is being introduced into gasoline cars too. The particulate filter is responsible for capturing the soot which is produced by the combustion process. If this filter becomes clogged, then this soot will settle inside the engine and start to contaminate the delicate parts inside. This issue needs to be resolved quickly as if the filter becomes damaged beyond repair, you are likely to be footing an expensive bill.

Best Louisville Garage to Repair Audi Engine Misfires

Best Louisville Garage to Repair Audi Engine Misfires

Owning a high-end and high-performance car such as an Audi comes with amazing driving experiences, incredible horsepower, and more. However, this doesn’t mean there aren’t a handful of drawbacks you’ll need to account for as well. In the case of Audi, one of the problems most commonly experienced is engine misfires. Misfires can be worrying for drivers and can also pose a real threat to engine health. Therefore, it is essential that you try to prevent misfires from occurring, and when they do occur, decide to deal with them quickly. Let’s look at ways to recognize Audi engine misfires and discuss what to do about them.

Dissecting an Engine Misfire

Your Audi’s engine is a fine-tuned machine of various parts and systems that all need to work in a precise order in order to achieve ignition. For example, there are processes such as power delivery which helps ensure you have drive, combustion which gives the energy for drive, and so on. When one of these important steps are skipped, the cycle is interrupted, causing engine misfires. A misfire may not be bad enough to cause your vehicle to fail to start. Instead, you might only notice minor misfires when driving, such as jerks, shakes, and rough idling.

Misfires can occur for many reasons such as lean misfire, where the air and fuel ratio is incorrect. Ignition misfire occurs when the fuel isn’t ignited. Last, mechanical misfires involve issues with any of the engine’s mechanical parts. Audi is known to experience all three of these types of misfire.

Common Causes of a Misfiring Audi

1. Pushing your Audi to the Limit

While one of the pleasures of a high-performance sports car is the extra horsepower you can access, pushing your car to its limits for that rush of speed. However, asking too much of your engine for too long or too often can really impact its overall health. If you want your Audi to have a long lifespan, we recommend easing off the need for a quick launch.

2. Failing Spark Plugs

Spark plugs work very hard to ensure you engine performs well. Because of this, depending on the type of plug used in your Audi, their lifespan can range between 30,000-50,000 miles for standard plugs or 80,000-100,000 for precious metal tipped plugs. Spark plugs that go past this lifespan or that become faulty or damaged will work less effectively than fresh or newly-serviced plugs. Replacing spark plugs at home is possible, but does take a little know-how. To do this, you first need to locate your Audi’s spark plugs and assess their overall condition. If there is contamination on the plugs or the metal is worn down, then you should seek replacement. You can do this at home with a how-to guide, or for complete peace of mind, bring your Audi into a specialist shop where they can also inspect your overall system and diagnose any issues before them become problems.

3. Failed Spark Plug Wires

To provide power to the plugs, spark plug wires need to be in perfect condition. When they become aged, they can be a prime culprit for misfires and will need replacing. This can be done at home if you feel confident in your ability to do so. If not, your trusted local Audi specialist will be happy to help you quickly and efficiently.

4. Fuel Injector Failure

You engine needs to have fuel delivered into the combustion chamber at the precise spray pressure and pattern. To do this, it relies on fuel injectors. However, given time and use, the injector nozzles can become clogged with debris, affecting their performance. The hose they are connected to can also become damaged, leading to vacuum leaks. These leaks can contribute to catastrophic engine failure if left unchecked. To prevent this, you should have your fuel injectors checked and serviced by an experienced professional who can alert you when it is time to replace any of the parts of the fuel injection system to help preserve your Audi’s overall engine health.

How Technological Innovations Are Transforming The Auto Repair Industry

How Technological Innovations Are Transforming The Auto Repair Industry

When it comes to auto repair, the team of highly educated auto mechanics at Turning Wrenches in Louisville are always up-to-date on the innovations happening in the industry. New technologies are being experimented with regularly, and Mercedes has always been a leader in these cutting-edge advancements. Here are three new things to expect in the world of automobiles shortly:

Self-Driving Cars: The future has arrived! Yes, many of us have seen self-driving cars in the movies, and now it’s something you’re likely to see sooner than you think. Google engineers in Nevada and California have already been testing these vehicles on public roads and highways. In the next decade, it’s looking like we’ll start to see these self-driving cars in showrooms.

Airbags that Helps to Stop Cars: Could an airbag help stop a car before a crash? Mercedes has been testing airbags that are outside a vehicle and deploy from the bottom of the automobile. When the sensors determine that a collision is unavoidable, the bags will open up. There’s friction coating on the airbags that allows the car to slow down and can increase the stopping power of the vehicle. The bags also improves bumper-to-bumper contact and assists in preventing people in the vehicle from sliding under seatbelts if there is a collision.

Energy Storing Body Panels: Body Panels that can store energy and charge faster are already being experimented with in Europe. They’ll be able to capture the energy created by technologies (like regenerative braking). The energy storing body panels are good news for the environment because the smaller battery would wipe out the wasted energy used to shift the weight of the batteries.

The Factory-Certified and Master-Certified auto technicians at Turning Wrenches are savvy at auto repair because we’re always up-to-date on current advancements. At our state-of-art facilities, we use only the most current tools, diagnostic systems, and equipment. Since Mercedes is so ahead of the curve on what to expect in the future in the automobile world, you can trust that the team at Turning Wrenches is always growing, changing, and improving right along with the industry.

Our highly trained auto mechanics have been performing thorough and accurate auto repair services on these cars for years, so we like to consider ourselves experts! Mercedes-Benz is one of the most popular car manufacturers in the world. However, the history of this automobile has some interesting facts that you might not be aware of. Here are a few three things that might surprise you:

  1. The First Person to Own a Driving License: The founder of Mercedes-Benz and inventor of the car, Karl Benz, was the first individual to be given a driver’s license. In 1888, the citizens of Mannheim, Germany were complaining about the load deafening sounds and smell produced by Motorwagen. Karl Benz received written permission from the Grand Ducal Authority to operate his vehicle on public roads.
  2. An Automobile that Resembles a Fish: The yellow boxfish, a fish that lives in coral reefs and is a native of the Indo-Pacific region was the inspiration for the exterior design of the Mercedes-Benz Bionic. The shape creates an excellent aerodynamic efficiency, so Mercedes-Benz was able to recreate the vehicle.
  3. Cars that Smell Better: Mercedes-Benz has an “active perfuming system” on the S-Class which releases four different fragrances created by Marc Von Ende. Car drivers can pick between four scents that were designed to complement the leather smell: Sports Mood (floral and outdoors), Downtown Mood (floral and musk), Freeside Mood (citrus), and Nightlife Mood (leather and wood).

Springtime Potholes: What You Can Do To Protect Your Vehicle

Springtime Potholes: What You Can Do To Protect Your Vehicle

With Spring arriving, the team of auto mechanics at Turning Wrenches in Louisville wants our clients to be mindful of potholes that often develop after the winter thaw. These annoying holes in the road can cause safety issues and car damage that could lead to substantial auto repair costs. If drivers report the loss to the city of Louisville, it is possible to get reimbursed for damages. However, the best bet would be to stay clear of potholes altogether! The team at Turning Wrenches has some suggestions on how to avoid these cracks the road:

  1. Grip the Wheel and Reduce Speed: If you can’t avoid the pothole, slow down so the impact won’t be as severe. To avoid losing control of the vehicle, grip the steering wheel firmly. It’s crucial not to use the brakes on a pothole as that could cause more damage to the car.
  2. Maintain Tire Pressure: Make sure that your automobile’s tires are correctly inflated (according to the car’s manufacturer).
  3. Be Mindful of Signs of Trouble: If you do hit a pothole, be aware of problems that immediately arise. For example, it could knock your automobile’s wheels out of alignment, which could cause your vehicle to veer in one direction and ultimately it could cause uneven wear on tires.
  4. Focus On Driving and Watch Out for Puddles: Pay close attention to the road and watch out for puddles. Sometimes puddles are potholes that are hard to detect.

Acid Rain and How It Affects Your Paint

Acid Rain and How It Affects Your Paint

Our team of knowledgeable auto mechanics at Turning Wrenches in Louisville are the trusted source for accurate and thorough auto repair services. It’s our mission to provide stellar auto repair, impeccable customer service, and take those extra steps to keep our clients abreast of things that could harm their vehicle.

For example, acid rain can cause significant damage to the paint on your car. Anything water based that falls from the sky is considered acid rain, which could include rain, dew, and snow. These elements could cause issues when it comes to your automobile’s exterior because the acidity of the water could cause the paint (and even the metal) to weaken over time. However, there are some ways to prevent this damage.

Our team at Turning Wrenches in Louisville suggests that you wash your vehicle frequently to prevent damage caused by acid rain. A professional car wash not only keeps a car protected and clean but also helps to avoid damage acid rain can create. Washing a vehicle regularly lessens the amount of acidic material left on the car, and when the car is clean, there will be nothing left to cause more damage. Also, hand drying the vehicle or completely covering the automobile when precipitation occurs can prevent problems caused by acid rain.

Our team at Turning Wrenches indeed has the best interest of our customers at heart. We want you to be driving a vehicle free and clear of damage caused by acid rain. We have customers who stay with us year after year because of our genuine commitment to educating clients, performing quality auto repairs, and offering above and beyond customer service. Our auto technicians are ready, willing, able to provide you an auto repair experience that will be unmatched by our competitors.

Why Salt Is Bad For Your Car

Why Salt Is Bad For Your Car

With winter approaching in Louisville, salt crews have been prepping the roads for the inclement weather. However, salt can cause damage to the car, and the auto mechanics at Turning Wrenches can assist with the auto repair if the salt damages your vehicle. Sometimes the problem areas might not be visible, and our team of talented technicians would be happy to make sure that your car is functioning properly.

While road salt is crucial to make winter driving safer, it’s also corrosive and can cause significant car problems over the long haul. The rotting can harm the vehicle’s frame, coil springs, and muffler systems. Salt can cause brake lines and fuel lines to freeze which could cause danger. Because of the way an automobile is built, the majority of salt damage happens underneath the car, making it difficult to detect. The team of auto technicians at Turning Wrenches highly recommend that you allow professionals to inspect those hard to reach and see areas, so you and your passengers feel more secure on the winter roads.

When you visit Turning Wrenches for auto repair related to salt damage, our team will take the time to perform accurate service and educate you about ways to prevent further damage. We’re so confident in our work that we offer a 3-year/36,000-mile warranty.

Our customers mean the world to us, so we take those extra steps that convince new customers to become long-term clients.

When salt on the roads causes damage to your car, we have you covered! If you’d like our highly trained auto mechanics to assist and provide thorough and top-notch auto repair, contact us at Turning Wrenches. We’re located at 1701 Mellwood Ave, Louisville, KY 40206.
