Common Issues if You Own an Audi

Common Issues if You Own an Audi Shaus Motorsport DenverHere at Shaus Motorsport in Aurora, we want to share some common issues if you own an Audi. Knowing what to look out for can help you spot symptoms early so you can get the issue repaired quickly. Early troubleshooting can help you avoid more costly repairs.

Of course, once you notice any of these common issues if you own an Audi, get in touch with our team, specializing in German auto repair for your elite vehicle.  

Burning Oil Smell and Oil Leaks

Audi engines typically leak from the tensioner gasket seals or the valve covers. Leaking oil can be a potential fire hazard and if you can smell the oil burning, it is best to get the issue fixed quickly. The smell is created by oil hitting the exhaust and burning while you drive.

Leaking oil can also be a danger to the electronics in your Audi.

The electronics can also be affected by an Audi leaking oil. It can permeate the wiring and cause damage to the control modules and electrical connections. The longer your oil leaks, the higher the likelihood that your repair is going to become more expensive. Additionally, the longer it continues, the less oil you have running through your engine, so it is important to address this issue quickly.

Clicking or Clunking during a Sharp Turn

Usually, this issue is the result of overlooking a needed repair on your axle CV boot. When the CV boot tears, the grease is expelled and the joint begins to wear out as a result of the lack of lubrication. Eventually, the entire axle assembly may need to be replaced. If you have a torn CV boot, get it replaced quickly to avoid a more extensive problem and repair.

Exhaust Leak

If your Audi sounds throaty when you accelerate, you may have an exhaust leak. A number of Audi models have a flexible joint between the catalytic converters and the downpipe in the exhaust. This joint is prone to leaking. While a deeper exhaust may sound cool, an extended leaking exhaust can become quite expensive.

If you suspect you have an exhaust leak, call us at Shaus Motorsport. We can determine the best next steps for fixing one of the common issues if you own an Audi.

Check Engine Light with a Rough Running Engine

If your engine is running rough and your check engine light has come on, you may have a cylinder that is misfiring. It is possible that your ignition coil is the source of this problem. In fact, your Audi may have been part of a recall for ignition coils. Your local repair shop can help you determine if your ignition coil needs to be replaced.

Check Engine Light is on, but Your Audi Sounds Great

If your check engine light stays on for multiple cycles and your Audi seems to be running fine, the trouble could be an emissions related issue. To figure out what’s causing your check engine light to come on, you need to bring your Audi in so we can provide a deeper analysis and locate the source of the problem. There are a number potential problem areas, all common issues if you own an Audi.

Low Coolant Light is on or Coolant Leaks

Your make frequently have trouble with the low coolant light coming on as Audis commonly have visible coolant leaks. The culprit could be a crack in the coolant reservoir. Sometimes, the leak can be difficult to find because the coolant will evaporate upon reaching the exhaust component. Thankfully, replacing the coolant reservoir is generally inexpensive when the repair is taken care of before the problem progresses.

Turn Signals Don’t Work or Stay On Continually

In older models, this is one of the common issues if you own an Audi. Frequently, the source of this problem is the hazard switch. Additionally, it could be related to a faulty switch in the steering column. This cause is not nearly as likely though.

Rattle/Knocking Noise

During a cold start of your vehicle, you may hear a rattle or knocking noise. This can be caused by an Audi’s camshaft adjuster or the camshaft chain tensioner. If this is the case, the noise will last for a second or two after the car starts. This noise can be normal on a particularly cold day. If it lasts for more than a couple seconds, the problem will need a more detailed diagnosis to determine the nature of the issue.

Unpleasant Odors from Ventilation and Heating System

If a musty odor is coming from your heating system, you may have an issue with mold in the ducts. The mold and the odor can be removed, however, repeated, regular treatments will be necessary to keep the mold from returning.

Turbo Car Blowing Smoke

If your turbo vehicle is blowing smoke, you need to have an Audi-trained mechanic look at it right away.  There are a number of simple reasons for the smoke, but getting it taken care of is a must to avoid a much more expensive repair. The worst-case scenario could be a failing or worn out turbo. Oil may be passing by the turbo and heading down the exhaust creating the smoke. If it is not taken care of quickly, the oil can destroy your catalytic converter and this will cause your repair to be much more costly.

You can remove the intercooler hose and if more than just a small amount of oil runs out of the hose, you have an issue that needs prompt attention.

Trunk Won’t Automatically Close

A voltage distribution module failure is another of the common issues if you own an Audi, and it’s one of those odd electrical issues like a truck that won’t close automatically or an MMI that opens or closes randomly. When the voltage distribution model is not working properly, various devices in your Audi will either exhibit strange behavior or fail to work. It is also possible that your vehicle’s battery needs to be replaced.

If you are experiencing any of these common issues if you own an Audi, contact us here at Shaus Motorsport in Aurora. We can track down the source of your trouble, get your vehicle fixed and help you avoid further repairs. Call for an appointment today.

BMW Tune-Ups and Maintenance

BMW Tune-Ups and Maintenance Shaus Motorsport DenverBMW tune-ups and maintenance can lengthen the life of your prized BMW. Here at Shaus Motorsport in Aurora, we think maintenance and tune-ups are an excellent way to improve the performance of your vehicle and reduce your chances of major issues. Though “tune-ups” aren’t really used the same way as they did in the past, you can certainly tune-up your engine by taking care of the following areas of your BMW machine.

Spark Plugs

A spark plug can tell you a lot about the condition of your BMW’s condition. Inspecting your spark plugs during regular BMW tune-ups and maintenance can reveal early possible problems. We recommend getting them checked every 30,000 miles and replaced every 100,000 miles. Changing your spark plugs avoids them seizing in the block which can result in expensive repairs in the future. Be sure to track which cylinder the spark plug came out of so that you are aware of which cylinder may have a problem.

Spark Plug Wire Sets

Spark plug wire sets used to need to be replaced with regularity. There have been dramatic reductions in failures and problems due to the use of better materials and sizing. They also now have increased operating ranges. These wires should be tested for proper resistance but they no longer warrant routine replacement like other parts of your BMW.

Distributor Cap and Rotor

The rotor and the distributor cap are generally plastic and so they often deteriorate with use over time. Cracks can develop which can let in moisture. Both the distributor cap and rotor have metal contacts that can corrode. If the contacts become worn, your BMW engine can misfire as a result. Be sure to have these parts replaced when they are worn or at least checked for issues during BMW tune-ups and maintenance.

Air Filters

Air filters trap dirt and other particles as the air passes through the filter. In older BMWs, the air filter helps to protect the carburetor. In newer models, the air filter is helping to protect the fuel injector. Generally, you should replace your BMW air filters every 20,000 miles. If you live in a dusty area or drive dirt roads, your vehicle’s air filter will need to be replaced more frequently. Any air filter that looks really dirty or is damaged should be replaced regardless of how many miles it should last.

Oil Filters

One of the basics of BMW tune-ups and maintenance is your oil filter which is simple to replace and doing do stops unnecessary wear on your engine. Oil filters remove rust, soot, and any other solid contaminants from your engine’s oil. They should be replaced every 3,000 miles at the same time that your engine’s oil is replaced.

PVC Breather Filter

Every 30,000 miles your PVC filter should be changed. Your PVC filter makes sure that only clean air is drawn through the PVC breather. If your PVC filter is clogged, your PVC is unable to siphon away the moisture and gases created by engine combustion. A clogged PVC filter will cause sludge buildup and can result in oil breaking down.

Fuel Filter

A BMW fuel filter stops various contaminants from getting into your fuel system. These contaminants can clog the injector inlet screens. The pintle valve and seat can also get clogged if dirt and contaminants get into the injector itself. In older cars, the fuel filter helps stop dirt from plugging up the carburetor’s fuel metering openings.

Clogged fuel filters can result in your vehicle stalling due to a restriction of fuel flow. They can also cause loss of speed power as well as hard starting. To avoid these problems, change your fuel filters every 30,000 miles, annually, or when other fuel system parts need to be replaced as well (whichever of these conditions happen to occur first).

Automatic Transmission Filter

Transmission filters help the transmission fluid stay clean enough to properly transmit energy as well as cool and lubricate the moving parts of your BMW transmission. If your transmission filter is clogged, your transmission may slip, have trouble engaging gears, and hesitate. To help your engine last longer, your transmission filter should be changed around every 12,000-15,000 miles during regular BMW tune-ups and maintenance.

Easiest Way to Extend Engine Life

If there is one thing that can easily and inexpensively help your engine last longer, it is changing your filters. If you need your BMW’s filters changed, contact us at Shaus Motorsport in Aurora.

Other BMW Maintenance Parts

There are other parts that are not technically BMW tune-ups and maintenance areas but they can help the “tune-up” work be more successful. Some of these may be viewed as not critical but that’s not really true. If your vehicle needs to pass emission tests, taking care of the parts are essential to keeping your BMW working properly and operating safely.

  • Oxygen sensor: Also called your O2 sensor, this engine part should be replaced at recommended intervals. A worn down oxygen sensor can change your engine’s settings in a negative way.
  • Vacuum hoses: Each vacuum hose needs to be checked and replaced as may be necessary. A number of your vehicle’s major systems rely on the manifold vacuum’s signals and functions. Even the smallest leak in your vacuum hoses can cause serious performance issues. In some cases, your BMW may not run with a vacuum leak and checking them can help keep you on the road.
  • Temperature sensors: The sensors in your vehicle control your cooling system, the exhaust system, and the fuel injection system. If one of your temperature sensors is not functioning properly, your BMW will likely not perform well either.

Other Tips for Your BMW

Cleaning your engine is preventative maintenance. If your engine is clean, it runs better and cooler. Clean engines also last longer. So, make sure that you’re taking care of your vehicle’s needs on a regular basis.

Keeping up with your BMW tune-ups and maintenance will keep your BMW humming and will help your engine last much longer. Contact us here at Shaus Motorsport in Aurora if you need some maintenance performed on your BMW.

About Turbochargers and How They Work

About Turbochargers and How They WorkHere at Shaus Motorsport in Aurora, we want to share more about turbochargers and how they work. Did you know that the turbocharger is actually a big improvement on the internal combustion engine? Thanks to the turbocharger, turbo engines can go further faster and use less fuel. Turbochargers, in a nutshell, are a pair of fans that use waste exhaust from the rear of an engine to force more air into the front of an engine. The result is more get up and go than you would get otherwise.

Turbocharger Inventor

The turbocharger was originally developed by Alfred J. Büchi. He was an automotive engineer who worked for the Gebrüder Sulzer Engine Company in Switzerland. His invention was patented in 1905, and he worked on improving the turbocharger for the rest of his life. Büchi was fascinated with everything about turbochargers and how they work. He felt that they could improve combustion engines dramatically.

Turbocharger Basics

Everyone can tell that a tailpipe streaming exhaust is polluting the air. What isn’t as noticeable is that such tailpipes are also wasting energy at the same time. Exhaust is actually a mixture of different gases being pumped out. Turbochargers harness the exhaust, using the heat, gases, and energy to actually help the vehicle travel faster. Turbochargers force more air into the vehicle’s cylinders, which in turn allows fuel to be burned faster. The faster fuel burns, the faster a vehicle can travel.

Turbochargers and Cylinders

Since cars go faster based directly on how much fuel they can burn, adding cylinders was the original way to get a car to go faster. This explains why sports cars typically have eight and twelve cylinders. Those extra cylinders will help burn more fuel quickly. Your conventional vehicle typically has just four or six cylinders. Owners of performance vehicles such as a BMW, Audio or Porsche may want to go faster. Installing a turbocharger is a great way to gain speed without more cylinders.

Turbochargers: Like a Small Jet Engine

When we talk about turbochargers and how they work, we often compare them to how jet engines work. Based on the same principles as turbochargers, a jet engine sucks in air from the front, squeezes the air into a chamber where the fuel is burned, and the blasts hot air from the rear. As the hot air exits, it blasts past a turbine that drives the air pump (also called a compressor) which is at the front of the engine.

Turbochargers do much the same thing as jet engines. Turbochargers are basically two little air fans (called gas pumps or impellers) that sit on the same air shaft and both spin around together.

One fan is positioned in the exhaust stream coming from the cylinders. This fan is called the turbine. The cylinders blow hot gas towards the fan blades which then rotate. The second fan, which is sitting on the shaft with the turbine, spins at the same time. This fan is called the compressor. It is mounted so that it is inside the car’s intake and as it draws the air in, it forces it into the cylinders.

Disadvantages of Turbochargers

You may be wondering why turbochargers aren’t in every vehicle, everywhere. Well, in theory, more power means more energy output (and speed) and this is a great thing. At the same time, more energy output means more energy input is required. Ultimately, these engines need more fuel and expend it faster which isn’t the right fit for everyone.

If you’ve read up on everything about turbochargers and how they work, you may already know that early turbochargers didn’t deliver quite the amazing results that manufacturers promised. While they were eager to lay claim to having better engines than the competition, the turbos sometimes turned out to be less impressive. Had there been less of a rush to get turbochargers to market and more time spent fine-tuning its capabilities, the turbocharger could certainly have gained wider acceptance.

Turbochargers are also a little different to drive. There is a slight delay between pressing the gas and having the car take off. There is even a term for it: turbo lag. This means turbos are a bit trickier to drive and not all drivers might appreciate the difference. But those who do, love what a turbocharger can offer on the street and track.

Finally, turbochargers make engines more complicated. It makes sense since you’re adding another component to an engine which is another part that requires proper maintenance. Additionally, turbochargers run hotter. This subjects engines to higher stress, which in turn, means that turbocharged engines don’t always last as long as conventional counterparts. It all really depends on the driver though. Even without a turbocharger, plenty of people with standard engines find countless ways to drive them into the ground prematurely.

Of course, if the turbo in your Audi, Porsche, BMW, or Volkswagen needs maintenance, repair or even a rebuild, you can contact us here at Shaus Motorsport in Aurora. We’ll make sure your turbo delivers on its promises, delivering the performance you want from it.

Advantages of a Turbocharger

When it comes to understanding all about turbochargers and how they work, their many advantages are the best part. Turbochargers can be used with either diesel or gas engines and, for the most part, can be used on cars, trucks, buses, and more. Basically, the primary advantage is that the same size engine can get a great deal more output. A turbocharged engine produces more energy with every stroke of each piston and in each cylinder.

Engineered and performing properly, a turbocharged engine can actually save up 10% of the fuel. These engines also tend to burn the fuel more cleanly because more oxygen is burned with the fuel. Manufacturers can now produce the same size engine, or sometimes even a smaller engine, and get faster and better results. What was once a V6 engine can now be a 4-cylinder with a turbocharger.

The advantages are what make us the most excited about turbochargers and how they work. If you need our specialists to take a look at your Porsche, Audi, BMW, or Volkswagen engine, contact us here at Shaus Motorsport in Aurora. We can repair, maintain and even fully rebuild your turbocharged engine – all in less time and at less cost than other shops.

Brush Up on These Winter Driving Tips

Brush Up on These Winter Driving TipsAt Shaus Motorsport, we know the days of winter driving will be here faster than you think, so brush up on these winter driving tips and get prepared. Driving in winter weather and snow in particular, can be a daunting task, even for those who have done it for many years. It can be especially challenging for those who have moved here from more temperate places.

Stay Home

If you have the option, staying home and off the road is one of the best ways to stay safe. Fewer cars on the road are a big help to people who have to be out there. So if it’s an option, take it. If not, read on and brush up on these winter driving tips.

Know You Car and Your Brakes

In snowy weather, knowing how your car operates under normal conditions is important, particularly your brakes. Brakes in winter are key to safe driving. It may be a great time to get your German vehicle’s brakes checked by a shop like Shaus Motorsport in Denver. It is a great time to be sure they are still in prime condition. If your car is new, you really want to be sure that you have an especially good understanding of your car and brakes prior to the first snowfall.

Increase Your Distance

In the snow, traction is greatly decreased and in some instances, it is compromised entirely. Because of this, you should put much larger distances between you and other cars. The additional distance will help by giving you more space to gather some traction and more room to maneuver if your car starts to skid or slide. Putting more space between your car and the cars around you also helps other drivers, which is great for people who are new to our cold, Colorado winters.

Careful Driver

The most important thing to remember while driving in icy and snowy weather is to drive with patience and care. While slow drivers can be annoying, it is much safer and will help preserve the pristine condition of your Audi, BMW, VW or Porsche, not to mention your safety! You can brush up on these winter driving tips presented here, but ultimately, remaining calm, careful and patient will go a long way.  

Avoid Stopping

One of the hardest things to do in the snow is stopping and once you do stop, you can get stuck. Additionally, it can take a lot of power and potentially a bit of sliding to get going again. Stopping while driving can be a necessity, but if there is an opportunity to avoid it, it is good to try. This often involves driving much slower and in a very careful and calculating manner. When possible, take your foot off the gas and allow your car slow on its own instead of using the brakes.

Have Your Car Serviced

A great way to avoid trouble in winter is to get your car checked before the snow and ice arrive. If you need your German car serviced – tune-up to brake repairs and more – call us at Shaus Motorsport in Denver. We can help keep you safe when winter arrives.

The BMW X7 SUV Has Been Unveiled

The BMW X7 SUV Has Been Unveiled Shaus Motorsport DenverThe BMW X7 SUV has been unveiled and we at Shaus Motorsport in Denver want to share some of the details with you just in case you want to be one of the first people to enjoy this new SUV when it finally hits the market. BMW’s newest large edition is bigger and more luxurious and it is loaded with tech.

Concept Release

BMW unveiled its X7 SUV at the Frankfurt Motor Show earlier this month. As with the rest of the BMW collection, the larger the number the larger the vehicle, so X7 is a fitting label for the BMW SUV. As with any concept, it is subject to change, so what you see may not be exactly what you get but it is always interesting to take a look at most of what will probably be headed your way.

According to BMW, this concept represents the pinnacle of the brand, and some have referred to it as BMW’s flagship SUV, so it’s been given a powerful look. This includes an imposing kidney grille, BMW badging, and slick LED headlamp units. It might be a too much for some, but others may enjoy the large front-end look.

Here’s more of what we know now that the BMW X7 SUV has been unveiled.

A Look Inside

Billed as a luxury model, this car lines up with much of what BMW is already doing. This concept SUV also includes a wide dash and an infotainment screen in the dash center. The vehicle includes BMW’s next generation I-Drive controls and the upholstery is plush leather to complete their luxury look. BMW went with sleek, clean, and high-tech cool in their interior design.

More Tech

The middle row has a pair of screens, so passengers can watch what they want and share what they are browsing with other screens. The X7 concept includes the full services of BMW Connected like other BMWs. There is a great amount of focus on work-related items and productivity, which hints at BMW expecting that people will be driven rather than driving themselves. There is high-tech under the hood as well—a combination of electric motor and regular TwinPower turbo engine.

Some Concept Features May Be Simpler

In the final product, you can probably expect the steering wheel to be a bit simpler than the concept car. The headrests will probably also end up being a bit smaller once this concept hits production. The X7 SUV will probably also lose some of the flash like the backlit crystal glass, but it is billed as a luxury model so quite a bit of the flash will still remain.

Debut in Production

BMW expects to put this concept on sale sometime in 2018. So if you are looking to add this BMW to your garage or replace your existing BMW, you won’t have to wait very long. The BMW X7 SUV has been unveiled and we at Shaus Motorsport in Denver think you might enjoy seeing it when it is out on the market.
