Audi vehicles are among the most durable, luxurious, and efficient cars on the road today. However, over the years Audis have been known to develop a few common electrical problems. And since electrical problems in any type of car can be tricky to diagnose, we present you with this list of 5 signs that your late model Audi may be experiencing an electrical problem. We’ll also discuss how they can be dealt with.
Power window won’t go up or down: This is one of the most common electrical issues with many cars that have power windows. Usually when this happens the door on the driver’s side goes out first proceeded by the other windows going out over time. The cause of this is a defective power window regulator, window motor, window switch or other issue. The solution here is relatively simple – have the power window issue diagnosed and the proper parts within the [...]
One of the main challenges for drivers who have cars with diesel engines is in knowing that some of maintenance that is performed on it cannot always be DIY. For example, handling the Diesel Exhaust Fluid (DEF or AUS 32) required in diesel engines is better off left to professionals. Professionals can make sure that the DEF being used is of the highest quality. When drivers purchase DEF by themselves or leave it to fill-up locations that don’t identify the manufacturer and brand name on the receipt it can lead to engine damage. And while it may technically be true that some drivers can refill this fluid themselves, this approach is not at all recommended. Let’s take a look at just what DEF is, what it does and why you are better off letting experienced professionals refill it in your car.
What it DEF?
Diesel Exhaust Fluid is a caustic solution, which is 32.5% urea [...]
Despite the Volkswagen emissions scandal that has placed the future of diesel acceptance in jeopardy, many American still prefer diesel engines over gasoline engines. In fact, as of 2016 there were more than 8 million diesel engine vehicles in the U.S. This is because many drivers find that diesel engines produce more torque, better fuel economy, and easier maintenance to mention just a few of their attributes. Let’s look at these and some of the other benefits of owning a diesel vehicle.
Better fuel economy: On average, diesel engines are far more fuel efficient than gasoline vehicles. This is because they generate more power from less fuel. They are able to do this due to their higher compression rating. Additionally, turbochargers can increase fuel economy even more.
Diesel engines produce more energy than gasoline engines do: With greater torque drivers are better able to carry heavy loads such as trailers, campers, etc than they [...]
Car owners whose vehicles are still under warranty are often concerned that taking their vehicle to a non-dealership mechanic for regularly scheduled maintenance or services may void the terms of the agreement. Well, we at Autohaus are here to assure you that it will not. You see, automakers and dealerships are not allowed to force you perform regular maintenance or service at a dealership in order for your warranty to remain valid. This is the law.
When searching for an independent repair shop to have your factory recommended maintenance, the key is whether or not they have the correct scan tools to perform this job. Autohaus has been in business serving the Royal Oak and surrounding areas since 1970. We specialize in German car repairs, which means we have all of the latest software and scan tools in order to perform diagnostics, scan for codes, perform maintenance, read Condition Based Service reports (for BMW), as [...]
You don’t have to be a Handy Andy to save on auto repairs. That is to say that doing your own auto repairs is not the only way you can reduce auto repair costs. In fact, with today’s high-tech vehicles and all their intricate components it is not a very good idea to attempt a great many repairs on your own. So, how do you reduce auto repair costs the next time you visit an Audi service center in Michigan? Here are just a few of our recommendations.
Use a reputable auto repair shop: A good auto repair shop will have Automotive Service Excellence (ASE) certified mechanics that are familiar with all car components. Moreover, they should be able to provide you with excellent customer service and be able to explain to you in detail every repair they are about to make and why it is needed. Finally, they should also be willing [...]
Your car’s exhaust system is comprised of a catalytic converter, two oxygen sensors, one or two mufflers, and a tail pipe. What all does it do? It helps route harmful fumes away from the engine and passenger cabin, it converts carbon monoxide into carbon dioxide, and it reduces engine noise. Some common signs of exhaust issues are:
Check engine light: Many times a check engine light can mean that there is an issue with a restricted catalytic converter, or “cat.”
Decreased fuel efficiency: Although decreased fuel efficiency can mean a great many things such as incorrect tire pressure, bad fuel injectors or worn out spark plugs, an exhaust leak is also a reason for this phenomenon. If you notice your MPGs have dropped then you may be in need of an exhaust system repair.
Decreased power and acceleration: Eventually a restricted exhaust system will begin to affect your engine performance. [...]
…but before Jack Frost settles in for the long haul, here are a few things you should do to make sure your vehicle is ready for the cold season.
1. Check your battery: Cold weather is very harsh on your battery. When those temperatures drop, starting an engine can take almost twice as much current as it would need on an average day. Have a technician run a load test to see if it’s time to replace your battery.
2. Have your cowl drains checked: Leaves may get stuck in the drains that run from the base of the windshield. This can cause water back-up and major damage to electrical [...]
Brake components for German cars have changed quite a bit over the past decade but the basic principals are still the same. Back when automobile manufacturers cared less about weight, fuel economy and performance, brake components were built to be heavy and strong. The excessive mass of the rotors allowed room for them to be machined or “cut” down, in order to smooth them out and reuse the rotors when the brake pads need to be replaced.
These days, rotors are designed to weigh less, increase performance and reduce fuel consumption. Automobile manufacturers have reduced not only the weight, but the overall thickness of the rotor. The reduction in unsprung mass is noticeable on modern cars and has achieved the goal the engineers intended. However, modern brake rotors cannot be machined as they are too thin to remove any high spots or groves [...]
Pothole season has arrived and that means many cars are on the road, right now, with one or more broken coil springs. Often, you will not even notice!
The coil springs allow the wheels and suspension to move vertically, while also holding up the body of the car. The length of the spring determines the car’s ride height, so if a spring brakes, the car will sit lower. The coil springs usually rust at the bottom where they attach to the suspension. They fit into a notch that tends to hold water, causing the bottom coil to rust and brake off. Since only a small portion brakes off, it’s not always obvious or noticeable.
A broken spring will affect the wheel alignment and can cause a rattling noise. It can be a safety issue because when a coil spring is broken, it is possible for it to become dislodged when going over a bump, and [...]
How to remove carbon buildup on intake valves on a direct injection engine
Carbon buildup on intake valves for Audi, Volkswagen, BMW and Mini
Carbon may be the building block of life, but it can wreak havoc on your engine.
Audi, Volkswagen, BMW and Mini engines utilize direct injection of fuel into the cylinder. Direct injection is where the fuel is sprayed at a very high pressure, directly into the cylinder through fuel injectors. The engine control module, or ECU, precisely controls all aspects of fuel injection, including the amount of fuel injected, timing, air to fuel ratio, how long the valves stay open and more. This process achieves better fuel economy and power because the combustion of fuel is more complete and the fuel burns more efficiently.
Air intake valves in all engines are exposed to air mixed with oil residue which can build up on top of the valves. Older, port style [...]
