Because the main, pertinent topic question is omitted from the thread title, it is misleading. It should be modified to reflect that you are focusing specifically on the TDI scandal and not the entire Audi brand.
Of course I’d buy an Audi. No, especially one connected to the smog cheating scam, I would not purchase a TDI.

Do Audi diesels work well?
Due to their distinctive qualities, such as good performance, high fuel efficiency, low emissions output, and low maintenance requirements, today’s new clean diesel models have garnered considerable appeal. When it comes to the design, production, and sales of cars with diesel engines, Audi is a well-known innovator.
How durable are Audi diesel engines?
Your automobile’s gasoline engine should typically last for roughly 200,000 miles before needing a significant refurbishment or you need a new car. However, diesel engines may operate continuously for an amazing 1,000,0001,500,000 miles before needing any significant maintenance. In actuality, a properly maintained diesel engine can last for 30 years or longer.
According to Capital Reman Exchange, there are three primary factors that contribute to a diesel engine’s lifetime, durability, and dependability:
- A diesel engine’s general layout
- the substance used in diesel engines
- The use of diesel engines in numerous applications
A diesel engine is gear-driven in design. Gears never lose timing, unlike other components that can be broken or damaged. They are also simple to repair. Gear-driven water and oil pumps may also be used by the majority of diesel vehicles. This reduces the possibility of parts and components breaking down.
Diesel-powered vehicles typically have heavy-duty construction that can resist the power of the engine, resulting in reduced wear and strain on the engine’s many components.
Diesel engines are excellent at self-cooling, which greatly reduces the likelihood that they may overheat. In order to prevent the engine from overheating, multiple sensors and thermostats are employed, so even if one fails, there are still others. A number of piston-cooling nozzles additionally guarantee a continuous flow of coolant through the engine.
A compression ignition system is used by a diesel engine to burn its fuel to produce power. When diesel fuel and air are sufficiently compressed, heat is produced, resulting in spontaneous combustion. This spontaneous combustion is much more favourable for a long-lasting engine, claims Digital Trends.
Are the 2.0 TDI Audi engines trustworthy?
When it comes to engine dependability, the VW/Audi 2.0 TDI has conflicting assessments, primarily due to oil pump and turbo issues. The VW emissions scandal, of course. However, these engines are generally reliable; many of them have lasted over 200,000 miles without suffering any significant engine damage. We’ve even witnessed some vehicles running at 400,000 miles like they were just purchased. The customer MUST keep up with all maintenance and use premium fuel with any Volkswagen or Audi engine.

Audi diesel or gasoline: which is superior?
It is evident that supporting one model practically cannot be done. Both the diesel and gasoline versions of the Audi A4 have advantages and disadvantages. You are entirely responsible for deciding whether to use a gasoline or diesel mill. There are several things that affect how decisions are made. Please keep in mind that diesel vehicles have cheap operating costs and reduced maintenance requirements compared to gasoline vehicles. Because diesel engines must handle greater pressure than a typical petrol engine due to higher combustion pressure, they require routine maintenance such as fluid changes. In a nutshell, diesel vehicles require expensive maintenance yet have cheap operating costs, and the opposite is true of gasoline vehicles.
It should be noted that a diesel variant has more power and torque than a petrol run variant, with 174.33 bhp at 4200 rpm and 380 Nm at 1750 2500 rpm compared to 167 horsepower at 380 06200 rpm and 320 Nm at 140 03700 rpm. Diesel outperforms gasoline on the mileage front as well, with run trims of 16.55 km/h in the city and 17.11 km/h on the roads for diesel vs 12.32 km/h in the city and 15.64 km/h on the highways for petrol.
The decision to choose an Audi A4 with a diesel or gasoline engine depends on the priorities of the buyer. In comparison to its petrol-powered counterpart, the diesel model offers better engine power and mileage. Additionally, a diesel-powered model can carry a bigger load because to the higher engine power (passenger and cargo). However, the engine is more noisy, more combustible, and expensive to maintain. On the other hand, the petrol version is lightweight and requires little upkeep.
Which of the outstanding sedans, the Audi A4 petrol or diesel, you choose will depend on your own preferences. You may also make a choice based on the needs you have for running. You can choose the diesel version if your daily commute is more than 60 to 70 km, but if it’s only 20 to 50 km, you should choose the petrol version. Both engines get about identical mileage. Although the power output of the diesel and gasoline engines is nearly equal, the diesel variant offers more torque.
If we choose one of these two, it would be unfair to the other. Diesel and gasoline each have advantages and disadvantages. For instance, the diesel engine claims to require high maintenance because it puts more strain on the engine yet is great for longer trips and provides superb low end torque and power while operating at low cost. On the other side, gasoline is better for city driving since it provides you more power and allows you to drive faster, but it has less maintenance and a high running cost because of the price of the fuel.
You were so kind to say that! Your response to the query will help hundreds of people decide whether to buy! After moderation, it will show up on the website.
Are TDI engines trustworthy?
Volkswagen has made numerous excellent diesel engines throughout the years, but the “ALH engine,” which was utilized from 1998 to 2006, is considered to be one of the best. With 1.9 liters of displacement over 4 cylinders, direct injection, and turbocharging, these engines were solely utilized in automobiles.
These engines became well-known not only for their exceptional dependability but also for the incredible fuel economy they were capable of. The Pumpe Dse engines, which employed camshaft-driven fuel injectors and were less dependable, began to replace the ALH engine about 2005. The common rail fuel system was added to the TDI engine later in 2008, and it is these newer engines that were the focus of the Volkswagen emissions-cheating issue.
With 500,000 kilometers on the clock, it’s not unusual to see diesel-powered Volkswagens still on the road. With between 300,000 and 500,000 kilometers on them, we disassembled and examined a number of 1.9L ALH engines. We were astonished by how little wear or other damage we discovered within. The fact that some of these engines were not kept up very well speaks to their toughness. The 2004 Jetta’s undercarriage housed an ALH TDI engine with 720,000 kilometers on it, which is the greatest mileage ALH TDI engine we’ve ever seen in our facility.
How long do TDI engines in the Audi A3 last?
Average annual maintenance and repair costs for an Audi A3 are $741. This is higher than the predicted $652 average for all vehicles across all segments but lower than the $801 average for other luxury compact automobiles.
Due to the luxurious nature of the Audi A3, components and maintenance will cost more than they would for a conventional car.
It will be less expensive to have your A3 maintained by a local independent mechanic that has experience working on German automobiles, but it is still advisable to get your car serviced by Audi while it is still under warranty.
How Long Do the Brakes Last?
The normal brake life of an Audi A3 is between 30,000 and 70,000 miles, though this can vary substantially depending on your driving habits. For instance, driving in heavy rush-hour traffic will hasten the brakes’ deterioration.
- Between $197 and $233 can be spent on parts and labor for brake pad replacement.
- You may extend the life of your brakes by allowing plenty of stopping distance and applying gentle, controlled pressure.
How Long Do the Tires Last?
Based on an annual mileage of 15,000 miles, Audi A3 tires should last roughly 34 years or 40,00060,000 miles. However, based on the state of the roads and driving practices, they may wear out significantly more quickly.
- To guarantee even wear, have your tires rotated every 5,000 miles.
- Make sure your tires are inflated properly; doing so will improve fuel efficiency. Every two to three weeks, check.
- Have a skilled technician inspect your wheel alignment every six months.
How Long Do Audi A3 Engines Last?
With standard maintenance, such as changing the oil frequently, the Audi A3 engine should survive for at least 200,000 kilometers.
The 2.0-liter turbocharged four-cylinder used in the Audi A3 is a well-built piece of machinery and is renowned for its dependability.
What are the drawbacks of diesel vehicles?
Diesel engine sales are increasing at a rate that has never been seen before. This technology won’t be obsolete anytime soon because the trend is anticipated to last at least through 2025. It is a technique that bears the name of its creator, a German engineer by the name of Rudolf Diesel.
During the Franco-German War, Diesel chose to leave his home country of France and move to England. He went home after the battle to start learning about engine design theories. He made important improvements to the steam engine concept in the 1880s, but the coal needed to run them was expensive and inefficient. He intended to develop something that would aid in the competition of small firms.
Diesel ultimately figured out how to build a tiny internal combustion engine that used the heat it produced to do work. Theoretically, one of them could potentially convert 75% of the heat it produced into energy. Because the fuel was heavier and less flammable by 1904, the French began utilizing his engines in their submarines.
The moment is right to assess the benefits and drawbacks of diesel vehicles as this technology develops.
List of the Advantages of Diesel Cars
1. Diesel motors are quite effective.
The compression-ignition system used by diesel technology is more effective than the one found in a typical gasoline vehicle. Diesels require additional compression to ensure that the air reaches the proper temperature instead of using spark plugs to generate heat for the operation. Because of the increased compression level, the engine runs hotter than a regular car’s motor. This indicates that the system produces more energy while requiring less fuel to do it.
This means that compared to gasoline-powered vehicles, diesel cars often have superior gas mileage. You can go farther without having to refuel, which can help you save some money. Compared to a comparable vehicle with equivalent performance, you’ll get up to 30% more mileage.
2. Due to their engine configuration, diesel cars are more durable.
Engineers must design diesel engines in a way that allows them to tolerate this climate because they must function at greater temperatures in order to be effective. This indicates that better materials and skill were used to create the final product. It is a benefit that the technology lasts longer than products powered by gasoline. To get this benefit, you must perform all required maintenance, but most car owners find it to be a worthwhile investment.
Several Mercedes-Benz models have original engines that have logged more than 900,000 miles. Even if you drive a lot (15,000 miles or more year), it would take you 60 years to get to that upper limit. The majority of engines may run for 300,000 miles or more before needing any significant repairs.
3. When driving, diesels provide you more torque.
When compared to gasoline-powered vehicles, diesel engines create more energy, therefore there is greater torque available for driving. This implies that whichever vehicle you choose to drive will have a substantially better towing capacity. This technology will provide you the extra power you need to complete the task if you want to buy a travel trailer or you frequently need to tow hefty loads.
Due to this benefit, you can operate a smaller diesel vehicle and still achieve performance that is comparable to that of a gasoline-powered passenger car. Many of them can accelerate from 0 to 60 in seven seconds or less and still reach up to 40 miles per gallon.
4. The resale value of a diesel vehicle is higher.
You’ll learn that diesel cars have a higher resale value if you followed the recommended maintenance schedule with your vehicle. The quality and lifespan of the engine will keep your diesel an enticing offer even if the car’s body isn’t in the best condition. Long after their gas-powered competitors have worn out, they remain a viable option because of their longevity, performance, and general handling.
5. Over the past 20 years, diesel fuel quality has substantially improved.
In order to be sold in the US, new diesel vehicles must adhere to the EPA’s most recent fuel economy and emissions requirements. Most adults can recall the 1980s and 1990s, when these cars were filthy, odorous, and significant environmental polluters. This fuel is now more pure than it has ever been. In 2006, the business began to change thanks to the development of ultra-low sulfur diesel, which is now required to meet both on- and off-road fuel standards. The new sulfur content restriction is set at fewer than 15 ppm, whereas the prior standard was set at up to 5,000 ppm.
Particulate emissions drop by 90% when the enhanced gasoline is used in conjunction with a cutting-edge exhaust emission control system, and nitrogen compound emissions can drop by up to 50%. To profit from this perk, you do need to buy a more recent diesel engine.
6. The price variation for some diesel vehicles is negligible.
Automobiles that run on diesel fuel do cost more than cars that run on regular gasoline. You can significantly lessen the discrepancies by using smart shopping techniques. To take advantage of this technology, you would need to spend an additional $2,500 on the Volkswagen Jetta turbo-diesel. Over time, driving that automobile frequently on the interstate would enable you to lower your overall ownership costs. Alternatively, you may target Volkswagen’s Golf TDI to get a comparable outcome.
7. Diesel vehicles can use more than one type of fuel.
You only have one fuel option if you buy an engine that runs on unleaded gasoline. To a certain extent, you can use ethanol blends, but doing so will reduce your gas mileage. You can choose to burn more than one type of fuel when driving a diesel vehicle. Waste vegetable oil (WVO) is a choice if you have a thrifty outlook. The grease that eateries produce is usually free to take. To stop the oil from congealing, you’d need to modify the engine, but it does work.
Additionally, you have the option of producing biodiesel on your own at home. If that situation arises, you can’t refine gasoline, therefore choosing this car will provide you more flexibility.
8. Some diesel engines have a quiet operation.
The 1.6L turbo-diesel engine that powers the 2018 Chevy Equinox goes by the moniker “whisper.” It offers a base of support that attempts to reduce the noise and vibration it makes while moving. According to General Motors, the engine is 65 percent quieter than the F-Pace diesel from Jaguar. Additionally, this car has a 577-mile cruising range, which allows you to drive for longer periods of time without being physically exhausted because there is less noise and vibration.
