Louisville’s Auto Experts for Repairing Alternator Bracket Seal in BMW

Louisville’s Auto Experts for Repairing Alternator Bracket Seal in BMW

As the owner of a vehicle as reliable and powerful as a BMW, ensuring this performance should be your number one priority. With this in mind, keeping all your parts up to date and keeping your vehicle properly maintained should be at the top of your to-do list. There are a number of issues that may arise which can turn into more serious issues down the line if not attended to, so tackling them the minute they appear is your best bet.

To that end, there are certain parts you should focus on fixing right away so that they don’t devolve into more serious problems. Doing so can help you maintain your car’s longevity and ensure that no additional problems develop.

One such issue that should be fixed right away is an alternator bracket seal being broken. To understand why this is an issue that needs to be fixed, we first need to look at what exactly the alternator seal bracket does.

What does the alternator seal bracket do?

The alternator seal bracket is a crucial component of your vehicle that keeps your alternator protected from leaks. As an overview, the alternator is the piece of machinery that allows the electricity to run throughout your car and power many components. With this in mind, you may be thinking that this is the battery’s function but it is the alternator.

Due to this function, the alternator is an extremely important part of your vehicle, and it would be damaged if oil were to leak into it. This is the exact function the alternator bracket seal serves. By stopping oil from leaking into the alternator, it prevents damage and allows the alternator to function as it normally would.

However, this seal doesn’t just stop oil from leaking into the alternator, but rather the engine as a whole. Oil is meant to be a lubricant for the engine and is not meant to be leaking outside of where it is supposed to be. Therefore, the oil running through your car should only be lubricating the engine and clearing it of debris, not dripping onto the floor.

With the above information in mind, take your vehicle into the shop immediately after noticing that something has gone wrong with the alternator seal bracket in your vehicle. Not doing so can leave your car vulnerable to extra damage and may prevent some parts from working as they should.

Signs of a Broken Alternator Seal Bracket

Spotting the signs that indicated when this important seal is broken is one of the most important things for any vehicle owner to do. Fortunately, there are a number of signs you can keep an eye out for that will tell you exactly when this occurs. Should you notice these signs, waste no time in heading to a repair shop.

  • You See Oil: Naturally, the best way to identify an oil leak is to see it with your own eyes. Check under the hood of your car if you suspect your vehicle is leaking oil and see if your suspicions are confirmed by a pool of dark liquid sitting on the ground.
  • Your Engine Loses Oil: The oil levels in your vehicle are very specific and are the reason you need to get your oil changed every so often. If you notice that your engine is losing oil far faster than normal, consider the possibility that your engine has a leak in the alternator seal bracket or somewhere else under the hood.
  • Oil-Pressure Light Activates: Similar to the check engine light, some BMWs have an oil-pressure light that can alert drivers when something goes wrong with the oil under the hood. It’s best not to ignore this light when it turns on and to take your car in right away so that you don’t lose more oil.

Where to Take Your Sputtering BMW Engine in Louisville

Where to Take Your Sputtering BMW Engine in Louisville

Of the many problems that can occur under the hood of a car, problems with the engine itself should be feared the most, especially on vehicles as reliable as BMW. The engine is the heart and soul of your vehicle. Any problem with the engine can potentially lead to engine failure or problems with other systems in your BMW.

Regardless of the cause, a sputtering engine is indicative of a serious problem within your vehicle’s engine. Any sputtering, even small sputters, should be looked at as a serious matter and should be a reason to take your car to be fixed without hesitation. Don’t allow the problem to spread to other areas of the car.

Causes of a Sputtering Engine

When it comes to the causes of a sputtering engine, the possibilities are potentially limitless but all serious. Fortunately, these can be identified fairly easily by any mechanic shop.

Fuel System

There are three major components that go into producing the optimal fuel reaction within the combustion bay: the filter, pump, and injectors. The filter ensures property flow of fuel and cleans the fuel, the pump moves fuel within the system, and the injectors spray specific amounts of fuel to the cylinder when needed. If any of these parts go bad, they may compromise the other parts and lead to improper fuel ratios. This could be a potential cause of engine sputtering.

Spark Plugs

The spark plugs on your vehicle are incredibly important and can become worn out over time. The spark plugs “spark” the air and fuel mixture within the engine. This drives the miniature explosion that sends the piston flying back down. If your spark plugs have become worn out, this reaction may not occur when it should or even at all. This would also lead your engine to sputter.

Catalytic Converter

The catalytic converter is responsible for turning carbon monoxide to carbon dioxide in the vehicle. As more pollutants stay within the engine, they can negatively affect performance and the air within the combustion chamber. This reduced performance may take the form of a sputtering engine by not providing the engine with the proper clean air to fuel ratio that it needs.

Effects of a Sputtering Engine

A sputtering engine may not seem like a worrisome issue, but the effects of this problem are far-reaching and have harsher implications for the rest of the vehicle. Below are just a few of the negative effects that can arise from a sputtering engine.

Dirtier Fuel Injectors

As mentioned, the entire fuel system could be the cause of the engine sputtering within your BMW. When the fuel filter becomes dirty over time and is left unchecked by a continuously sputtering engine, the fuel injectors themselves may become dirtier. This leads to contaminated fuel entering the combustion chamber, resulting in more problems.

Dirty Mass Airflow Sensor

Another effect of a sputtering engine is a dirty mass airflow sensor. This component is what measures the amount of fuel and air in the vehicle. A sputtering engine can result in a dirtier sensor that fails to do its job properly, worsening the problem.

Exhaust System Leaks

As referenced, the catalytic converter may be the cause of a sputtering engine by letting harmful pollutants into the engine bay. It should be obvious to you when exhaust system leaks occur, as the sulfer smell may be extreme and smell rotten.

Common Oil Leak Spots in a BMW

Common Oil Leak Spots in a BMW

When you drive a BMW, you expect excellence above and beyond that of the average vehicle on the road. The brand is built on smooth performance, sleek style, and above all, mechanical perfection. When a BMW owner drives off the lot for the first time, they can expect nothing but excellence from their new vehicle.

That just makes it all the more jarring and frustrating when one of your engine’s parts calls it quits, be it a problem as big as a blown catalytic converter or as small as an oil leak. While it’s normal for your BMW to have some small fluid drips in and around the engine (such as condensation from the A/C system), what’s not normal is when you notice puddles of fluid beneath your BMW every morning. That begs the question: where is the oil coming from?

The Importance of Oil in Your Engine

Oil in your engine is responsible for cooling and lubricating all of the heated moving parts. Your oil makes sure that your engine does not overheat or wear out too quickly through normal use. Without it, you run the risk of severe and extensive engine damage that may result in your engine overheating.

Furthermore, without oil, the more heat-sensitive parts of your engine may break or crack after repeated exposure to hotter-than-normal temperatures.

Here are the most common locations of oil leaks in your BMW:

Oil pan gasket leaks

Perhaps the most common leak of all comes from the oil pan gasket. The oil pan in your BMW is where your oil sits when the vehicle is not in use, and therefore can accumulate sludge and mineral deposits over time from old or hot oil, which can wear at your oil pan gasket over time.

Valve cover gasket leaks

This is one of the most common locations to experience a leak in BMW. The valve cover gasket protects the rocker arms and valves at the top of the engine. Typically, valve cover gasket leaks are more common after 60,000 miles, although a defective gasket can leak much sooner.

Rear main seal leaks

The rear main seal tends to fail when the crankshaft of your BMW encounters too much wear. When that happens, the main seal may be unable to hold tight or it may be otherwise damaged and may begin to leak.

Timing cover gasket leaks

The timing cover gasket is the seal that protects the connection between the engine block and the timing cover. If the timing cover gasket is the issue, you may also notice that coolant is leaking as well.

Oil filter housing gasket leaks

If you notice that oil is leaking only on the left side of the engine or if it looks like it’s coming from the oil pan but not the oil pan gasket, the leak may actually be coming from the oil filter housing gasket.

Common Causes of Oil Leaks in Your BMW

The cause of your oil leak is dependent upon where the leak is coming from. However, some causes are more common than others:

  • Old age and high mileage are one of the most common causes of oil leaks in any vehicle, as the wear and tear over time causes some parts to fail.
  • Inconsistent oil changes and improper oil type can cause oil deposits to build up in your oil pan or other parts of your engine.
  • Rough driving habits can overexert your engine, which leads to the components of your engine potentially being damaged.
  • A loose filler cap usually occurs when the cap is improperly replaced after an oil change. This can cause oil to leak from your pan.

Signs of VANOS System Failure in BMWs

Signs of VANOS System Failure in BMWs

The reason why BMW is so well-regarded for the incredible driving and handling of their cars is largely thanks to their unique VANOS system. This high-tech part achieves what was thought impossible. It gives you the best of both worlds: smooth driving and increased power. The only true drawback to this part is when it fails, you notice it. A failed VANOS unit will contribute to a drastic decline in performance. Therefore, it is important you look after your BMW’s VANOS system and keep an eye out for the early signs of failure.


VVT units exist in many modern cars, but the VANOS system is unique to BMW cars and is the manufacturer’s rendition of this common part. BMW was one of the pioneers of VVT, and their first VANOS system was released in 1992. This changed the high-performance driving game for ever. Engine performance was dramatically increased through the reflexive manipulation of the intake and exhaust valves. Added bonuses were smooth idling and increased torque, which led to an all-round improvement in power, performance, and handling.

Additionally, the VANOS system can also regulate the flow of engine oil that the cam gears receive. It does this using solenoids, and this ensures that timing adjustments are made with the maximum level of precision. There are currently three types of VANOS systems: Single VANOS (1992 to 2002), Double VANOS (1999 to 2010), and Double VANOS with Valvetronic (2004 to 2015). So the age of your BMW will directly impact which type of VANOS system your vehicle uses.

Signs of VANOS System Failure

As previously mentioned, an overall decline in your BMW’s performance will likely indicate an underperforming VANOS unit. However, this decline may be subtle and happen over time, making it hard to notice. So, keep an eye out for the following signs:

1. Loss of Torque/Power

As the VANOS system boosts the power and torque created by your engine, if it is under performing, the power and torque output that your engine can achieve will be reduced.

2. Engine Hesitation When at Low RPM

Low RPM commonly occurs when idling, such as when in traffic or waiting at an intersection. When the VANOS system is lacklustre, the engine’s timing won’t be precisely regulated, resulting in both power loss and engine hesitation at low RPM.

3. Rough Idle

One of the great things about the VANOS system is how smoothly it makes your VANOS drive. Therefore, it’s common sense to expect that when the VANOS system becomes sub par, your car will drive much less smoothly. Also, rough idling is likely to occur.

4. Reduced Gas Mileage

The VANOS system is responsible for getting the very best in efficiency out of every part it interacts with. When it isn’t working properly, your engine won’t function at peak levels, which can result in increased fuel consumption.

5. Cold Start Problems

Many cars can struggle with cold starts, but add in a faulty VANOS system, and it’s likely you’ll find it much harder to wake up your BMW.

6. Stalling in Cold Weather

On a similar note, when winter hits and your VANOS system isn’t working, you can expect an increase rate of stalling and an unhappy, uncooperative engine system.

7. Generation of Fault Codes

Your BMW’s onboard computer (ECU) is likely to pick up on the overall reduction in engine performance and may generate error codes pertaining to the VANOS unit. If the problem becomes severe, the ECU will likely trigger the Engine Management Light (EML or check engine light).

8. Engine Goes Limp After Accelerating

Your engine works hardest when it accelerates. As the VANOS system helps make this easier by making sure timing is perfect, when the VANOS system is not operational, the engine will not be able to correctly regulate its timing. This typically results in a sharp decline in power post-acceleration and a limp engine.

Here at Turning Wrenches of BMW VANOS System Repair Louisville, KY, we’re eager to help the BMW drivers with their VANOS problems.

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.
