7 Signs Your Audi Needs Maintenance

Audi Needs MaintenanceDriving a luxury car like an Audi requires extreme attention to detail. These cars need a special type of maintenance to perform at their best.

As a car owner, you should be doing your due diligence to ensure your car is at optimal performance level. If not, you're gonna have to dish out cash for serious repairs.

We've created this guide to show you the signs that your Audi needs maintenance.

1. You See Signals Flashing on Your Dashboard

Nowadays, cars have an electronic computer system that alerts you to a number of vehicle maintenance issues.

However, not everyone reads their driver's manual. Some drivers have no idea what those flashing lights mean, and that proves to be very dangerous.

Especially when your Audi needs maintenance.

The first thing I suggest is to read the owner's manual. It will tell you everything you need to know about the make, model, and computer system.

Audi employs a mileage-based system that alerts you to maintenance needs after you've driven X amount of miles.

Your manual should also include a standard maintenance schedule to keep you up-to-date with repairs.

Every car goes through wear and tear, and experts suggest a standard maintenance check after one year or 5,000 miles. After 5,000 miles, you need to change your oil and filter, check the brake system, and check/rotate tires.

2. Smoke

Smoke is always a bad sign. People usually panic when they see smoke and think the engine is on fire or the car might explode.

In truth, smoke usually signals a problem with the exhaust like a valve issue.

Believe it or not, smoke also ranges in color. Blue and gray smoke mean different things.

Smoke can also signal a bigger problem such as a blown gasket. Pay special attention to the color of the smoke.

Blue smoke means the engine is burning oil through the valve, piston rings, or spark plugs. If you have a turbocharged car, blue smoke means something is wrong with the turbocharger.

Gray Smoke

Gray smoke has a few different meanings. It could mean a transmission issue. The vacuum modulator could be malfunctioning and leaking fluid into the engine.

Gray smoke can also mean an issue with the PCV system. When the PCV valve isn't operating properly, oil starts to leak.

White Smoke

White smoke suggests a significant problem with the vehicle. It could mean any of the following:

  • Coolant Leakage
  • Blown Head Gasket
  • Damaged Cylinder Head
  • Cracked Engine Block

Black Smoke

Black smoke always means an issue with the engine.Make sure your air filters, fuel injectors, and fuel-pressure regulators, and fuel return line is working properly.

3. Ignition Coil or Spark Plug Problems

Ignition coils and spark plugs are interconnected. The ignition coil powers the ignition which lights up your spark plugs. Ignition coil failure leads to an engine misfire.

Ignition coil failure is usually caused by excess heat, vibration, and voltage overload. Excess heat or vibration damage the windings and insulation in the coil.

Open spark plugs or plugs with an excessive resistance increase the coil's output voltage levels. High voltage levels burn through the coil's insulation and cause circuit shortages.

In extreme cases, the engine will not start or run.

4. Oil Leaks

An oil leak is a common car issue and your Audi needs maintenance if you notice oil puddles under your car.

The oil dipstick should tell you if the engine is in need of oil. Low levels mean your engine is leaking oil. You should also be on the lookout for blue smoke.

As we mentioned before, blue smoke is a sure sign of an engine issue.

If your engine is leaking oil, it's probably caused by one of these four things:

  • Oil Seals
  • Degraded engine gaskets
  • Bad Connections
  • Oil pan leaks

Visit your mechanic right away once you identify a leak. Leaks can lead to engine failure. Typically, an Audi leakage problem is linked to the valve cover gasket or the camshaft tensioner.

5. Fuel Caps

The vehicle information display system should alert you to a loose fuel cap. This could be as simple as checking your gas tank and screwing the cap in or getting a replacement.

In addition to the fuel cap warning, the display system will also ignite the "check engine" signal. That's because a loose fuel cap leads to low gas mileage.

6. Catalytic Converters

Although your catalytic converters are made to last for a decade, these problems can arise, causing you to need replacement converters for your Audi:

  • Contamination
  • Clogging
  • Overheating
  • Damage

Converter contamination is caused by gas with high levels of lead, engine coolant, and oil. Once the converter is clogged, it's hard for exhaust gases to exit the vehicle.

When the exhaust system is compromised, oxygen can't enter the system and the engine becomes slow.

Overheated catalytic converters are the result of a faulty exhaust valve or spark plugs that misfire. The defective valve or spark plugs make it hard for the Audi to properly burn gas.

Excess amounts of unburned gas create overheated catalytic converters.

Be on the lookout for smoke. Black smoke can be a sign of catalytic converter issues.

Other signs include the following:

  • Strong sulfur or egg smell coming from the exhaust
  • Slow engine performance
  • Overheated engine
  • Acceleration issues

7. Exhaust Gas Re-Circulation (EGR)

Exhaust gas recirculation is a system that takes a portion of the engine's exhaust fumes and circulates it back into the intake air. By substituting burnt gas for oxygen, the system helps to reduce nitrogen oxide.

A valve is the mao component of the system that allows gas to flow through.

The system works within the combustion chamber to lower the cylinder temperature. Some cars are equipped with an EGR cooler, to cool the gas before it passes through the EGR system.

The biggest issue with EGR systems is carbon build-up.

When your EGR starts acting up, you'll notice problems with your engine. Engine problems are a sure sign that your Audi needs maintenance.

Fuel efficiency and acceleration problems could be a sign that it times to check the EGR valves.

Performance Upgrades for More Horsepower

car engine repair Shaus Motorsport DenverIf you are looking at performance upgrades for more horsepower, Shaus Motorsport in Aurora has you covered. We understand that you love your high-performance vehicle, but we also know that sometimes more horsepower and more torque can make a great car feel top of the line. There are a few ways to assist you in a quest for better vehicle performance and Shaus has all the parts and expertise needed to help you achieve your goals.

Cold Air Intake

One of the easiest and most affordable ways to maximize your horsepower is to upgrade your cold air intake. Upgrading your cold air intake allows the air coming into your engine to reach colder temperatures. Colder temperatures make the air denser and allow your vehicle to produce more power. This upgrade involves installing a different filter.

Some of the innovatively shaped filters offer 3x the surface area of your factory-installed filter. These parts are also designed to reduce unwanted turbulence and airflow resistance, both of which can cause a reduction in airflow to your engine. This is one of the easiest performance upgrades to achieve more horsepower for your Audi, BMW or Porsche vehicle.

Increase the Diameter of Your Throttle Body

The throttle body in your vehicle works together with your fuel injection system to regulate the airflow to the engine. Air is required to allow your engine to fire properly and so it is important to your engine’s function. A throttle body with a larger diameter and bigger flaps lets more air flow into your engine and in turn, maximizes and improves several aspects of your vehicle’s performance. With a larger diameter in your throttle body, you feel the faster acceleration and a surge in engine power. You can further enhance torque and improve your fuel economy by installing a throttle body spacer.

If you want to improve your horsepower and torque, contact our team at Shaus Motorsport in Aurora to discuss your needs and schedule an appointment. We can help you get the performance upgrades that you want from your high-performance vehicle.

Exhaust Headers and Manifolds

Many vehicle manufacturers must meet various emission requirements and maintain low production costs. This means that your stock manifold may not be moving air as efficiently as it has the potential to do. This means that aftermarket exhaust headers are an excellent possibility for obtaining extra horsepower and torque.

Additionally, changing your headers can also help. Both shorty and long-tube headers can help you achieve better performance. Both help move air faster and more effectively. Long-tube headers may be best for high-revving rides. These headers are great for building mid-range torque and horsepower to top end RPMs. Shorty headers are better for the lower RPM range and will still help with delivering torque and horsepower.

Catalytic Converters

Your stock catalytic converter functions very similarly to a high-flow catalytic converter, but a high-flow can still be one of the more useful performance upgrades you can have done. A high-flow catalytic converter makes sure that emissions are reduced quicker. This is done because the high-flow converters have an increased volume surrounding the catalyst and a less dense cell count internally.

The increased flow capacity of your engine allows it to produce more power. This power increase is most noticeable in the lower RPM range, but a high-flow catalytic converter achieves a power increase in both torque and horsepower across the range.

Replace Your Stock Muffler and Exhaust Pipe

Your stock muffler and factory exhaust pipe can be surprisingly restrictive. You can replace them with a high-flow cat-back exhaust system. It is called this because is placed behind your catalytic converter. If you pair a high-flow cat-back exhaust system with a high-flow catalytic converter, the combination can be one of the more powerful performance upgrades.

For the most impressive gains in your torque and horsepower, use systems that have large-diameter, mandrel-bent pipes. Additionally, some cat-back systems have straight-flow mufflers.  These mufflers can further enhance exhaust airflow and contribute further to more power.

If you are looking to exchange your factory muffler and exhaust pipe, contact us here at Shaus Motorsport in Aurora. We can make sure your choices achieve the increase in power that you want for your high-performance engine.

Performance Programmers and Chips

You can utilize performance chips and power programmers to change the controls of your factory-programmed computer and enhance your vehicle’s performance capabilities. These types of programmers and chips can adjust your vehicle’s settings and easily maximize your horsepower and torque.

Performance upgrades in your turbo boost and engine timing, as well as your fuel-to-air ratio, can all have an impact on your engine’s ultimate performance. The best part is that such performance software is easy to use and install. They even often offer pre-made and pre-programmed selections, along with customizable options.

Superchargers and Turbos—Your Forced Induction System

The greatest performance upgrades can come from compressing the airflow into the engine of your vehicle. This is often done by using forced induction systems, like superchargers and turbochargers. Forced induction systems are capable of increasing both horsepower and torque 50% or more. Adding more air allows your engine to mix in additional fuel faster which increases the overall power that your engine can produce.

A supercharger is powered by a belt that directly connects to your vehicle’s engine. On the other hand, turbochargers are powered by using excess energy from the exhaust stream. This is the primary reason turbochargers are considered to be more efficient but there is a delay (also known as turbo lag) in the production of power. Superchargers are considered to be easier to install and offer instant power, but they are less energy efficient.

If you need performance upgrades for more horsepower and torque for your high-performance Porsche, Audi, BMW, or Volkswagen, we here at Shaus Motorsport in Aurora can help. We can make recommendations about which of these options would serve you best and help you determine whether all of them will help. Contact us for help getting the performance you want from your vehicle.

What Are the Benefits of an HID Conversion

What are the benefits of an HID conversion? Here at Shaus Motorsport in Aurora, we want to share a bit about HID (High-Intensity Discharge) xenon headlights which are the newest thing for modifying all types of vehicles. HID headlights look cool and provide several benefits that you might enjoy adding to your car. And when you’re ready, come see us for install.

Improved Brightness

HID headlights offer improved brightness for nighttime driving. These headlights can be 3 to 5 times brighter than a regular halogen bulb and this is a considerable improvement. This upgrade has been achieved by combining xenon gas with an electrical charge. The electrical charge agitates the gas producing a whiter and brighter light.

Halogen lights have a filament that is heated to produce their light output. The lamps are usually yellowish and use twice the amount of energy to produce light. This makes the HID headlights a much better option overall.

Better Visibility

The quality of your nighttime driving visibility will be substantially improved with HID xenon headlights. The beams are bright and bolder. These lights allow you to see a much broader field both on the periphery and in front of your vehicle. This can be a great way to see obstacles well before you would be able to with halogen or regular bulbs. Bottom line, one of the benefits of an HID conversion is greater nighttime safety.

Better Durability

HID xenon bulbs can last several times longer than a standard bulb. This allows for you to have great visibility and reduce the number of times you need to change the headlights on your vehicle. If you want to get your headlights converted, contact Shaus Motorsport for assistance. We can get them installed for you quickly so that you can have these durable, high performing lights on your next nighttime drive.


Again, HID xenon headlights add to your everyday driving safety. Because you can see better and further, you will be safer while you are driving. Lack of visibility can be a factor in so many accidents. These headlights can give you a safety advantage while you are on the road and allow you a better peace of mind when driving at night.

Consider Using a Professional

You will see a number of websites for HID xenon headlights and as with any aftermarket product, you want to choose carefully. Many products will talk about the ease of installation and how inexpensive their product can be. Some of these products may not fit your specific vehicle very well and others may be inexpensive because they are too cheaply made.

Having a professional help you will ensure that your conversion to HID lights is going to fit properly and that you are getting a better product. Additionally, some older vehicles may not be well suited to having HID lights and a professional can make you aware of such issues in advance.

What are the benefits of an HID conversion? Increased visibility, improved brightness and greater durability are solid advantages. They also look pretty cool, too. If you want to get HID headlights installed, contact us here at Shaus Motorsport for your conversion needs.

The All-Electric Porsche Mission E

The All-Electric Porsche Mission EThe all-electric Porsche Mission E prototype is out and we at Shaus Motorsport in Aurora thought we would share what we know. The Mission E is out in public near Porsche’s German development center in Weissach so it seems like a good time to give a preview of what to expect from the Mission E in 2020.

Different Than the Panamera

As some of you know, Porsche sells the Panamera, which is a hybrid sedan. Yet, Porsche is not simply modifying the Panamera to create this new Mission E. The Mission E will have a lithium-ion battery making up its floorpan, much like the Tesla, between its two axles. It will have replica exhaust tips but do not be fooled, this is an all-electric Porsche.

There are rumors that the Mission E platform will be the basis for the all-electric SUV that Audi plans to put out soon. There is also talk that Lamborghini has an electric car in the works that models itself on the Mission E—but that could just be talk. It looks like the Mission E is the next big step in the all-electric field and others are taking notice.


The all-electric Porsche Mission E is expected to follow Porsche’s existing hierarchy, so you will likely see a Mission E S or a Mission E GTS. We don’t expect to see a Mission E Turbo though since the Mission is electric and won’t have turbos. The Mission E is likely to be offered initially with three power outputs: 402 hp, 536 hp, and 670 hp. The Mission E will also have all rear drive with electric motors at both the front and rear axles, much like the Tesla Model S does. Eventually, Porsche might offer a rear-drive, entry-level version of the Mission E, so be on the lookout.

A Smart Drivetrain

The all-electric drivetrain Mission E concept car features 605 hp, from the two permanent synchronous magnet motors on each axle. The motors are much like the ones used in the 919 LMP1 hybrid. You may remember that it is the one that won the Lemans three times and can recover heat-energy from braking. Porsche indicates that its concept can reach 60.5 mph in 3.5 seconds and 124 mph in less than 12 seconds.

The all-electric Porsche Mission E will probably have torque-vectoring and four-wheel steering. Porsche really wants this car to drive much like a true Porsche which is a great sign.

A Panamera Price

We expect that the Mission E pricing will start at the same level as the Panamera. In the United States, the Panamera base car begins at $85,000. The most expensive that a Panamera get is $190,000—the cost of the Panamera Turbo S E-Hybrid Sport Turismo. The Mission E price range should sit in the middle of the Panamera and the 911. A base 911 Carrera starts at $91,000. Keep in mind that the rival to the Mission E, Tesla’s Model S 75D starts at $74,500 so the all-electric Porsche Mission E is going to be more.

Comes With 800-Volt Fast Charge

With more money, you should be getting more and Porsche is trying to deliver a longer distance and a shorter charge time with the Mission E. Tesla uses 480-volt charges that offer approximately 170 miles of driving distance and takes 30-minute to charge. Porsche is trying to produce an 800-volt system that will offer a range of 250 miles and only take 15 minutes to charge. Of course, they are trying to accomplish this using the common house plug.

According to Porsche, the concept car has 310 miles of driving range. Porsche did not indicate the size of the battery pack. It is important to note that electric vehicle testing in the US and Europe are different, so it is not yet clear how the Porsche Mission E will compare with the Tesla Model S.

Concept is a Preview of the Production Visuals

The futuristic look of the all-electric Porsche Mission E is combined with classic Porsche proportions and it is eye-catching. Thankfully the production car is expected to stick close to the slick look of the concept. There may be some minor variations, of course. That is generally the case with any production model but the idea that it will closely resemble the concept is exciting.

First in a Line of Electric Porsches

Apparently, Porsche has already started working on a smaller version of the Mission E because the Mission E has a scalable platform. Porsche may be looking at potential different body styles and Porsche may already be planning its next all-electric model. This means that the Mission E is a prelude to the future of Porsche vehicles.

The 911 may always have a flat-six behind the rear axle, but there is a possibility that the future Cayenne, Macan, and Panamera will be all-electric as well. The Mission E may be Porsche’s first fully electric car but it looks like it will be far from the last one we will see from them.

It Will Be on Sale by 2020

As long as there are no unexpected delays, we should see the all-electric Porsche Mission E coming off the production line by the end of 2019 for the 2020 model year. At the Frankfurt Model Show in 2019, there could be an unveiling if all goes well for Porsche. This was where the concept made waves back in 2015. It would be great to see it come full circle in 2019.

The Mission E is a groundbreaking foray for Porsche. It could be a big change for Porsche and their hardcore fans, but the changes could bring exciting things for the company and its customers. The all-electric Porsche Mission E is the first of what could be a great future for Porsche. We here at Shaus Motorsport in Aurora can’t wait to see these cars out on the road. If your Porsche is due for some work, contact us here for your Porsche’s needs. We take good care of our customers and their cars!
