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.

About Trey
I have a passion for Volkswagen and Audi vehicles and spend my weekends working on them. I also appreciate assisting others by offering insightful and correct knowledge in the field of automobiles. I’ve worked in the automotive sector for at least ten years, and I make it a point to never stop learning new things. I hope that my posts reflect this passion and help the readers.
Do the 2.0 TDI engines in Audi have issues?
Failure of the diesel particulate filter is another issue that the 2.0 TDI engine is frequently associated with. There have been reports of the filter failing from clogging. Even though most diesel engines have this problem, the VW 2.0 TDI has it a lot more often than most.
Modern diesel engines use diesel particulate filters, or DPFs, to clean the exhaust emissions. By capturing diesel particulate inside the filter, it accomplishes this.
The TDI’s DPF may stop working as a result of sensor failure or clogging after a prolonged engine run. The DPF fouling inhibits the engine from breathing correctly, which causes it to malfunction and illuminate the amber warning light.
Avoiding short journeys is one strategy to avoid clogs. High RPM long-distance journeys will aid in burning any shoots that may clog the system.
Signs of a Failed Diesel Particulate Filter
An obvious indication that a particulate filter has failed is black smoke coming from the exhaust pipe. Check for low engine performance and high oil usage to identify this problem as well.
Solutions
The best course of action is to clean the DPF by clearing the soot because a failed DPF typically results from blockage. Cleaning the shot will assist the DPF return to its original condition without costing you any money. An pricey replacement serves as an alternative.
While the cost to clean a DPF might range from $150 to $300. A replacement might cost up to $900.
How trustworthy are 2.0 TDI motors?
The well-liked and praised 1.9 TDI engine was replaced with the 2.0 TDI engine. Additionally, although being significantly more modern than its predecessor, it is widely believed to be significantly less durable.
The majority of 2.0 TDI engine issues are caused by material savings and technical faults. The engine was first used in the 2003 Volkswagen Touran and thereafter continues to be represented in the majority of Volkswagen models before appearing later in various Mitsubishi, Jeep, and Dodge vehicles. The 1.9 TDI, while unquestionably enjoying a level of popularity as its predecessor, regrettably did not inherit durability from it.
The 2.0 TDI PD is available in a variety of configurations, with 8 valves producing 136140 hp and 16 valves producing 140170 hp. Versions of the 2.0 TDI were offered with a soot particle filter. Because of ongoing modernizations in response to more stringent rules for exhaust emissions, different engine types provide different options. The exceptional performance and low fuel economy of the 2.0 TDI PD engine are highly praised. The engine is installed in a variety of well-known Volkswagen Group cars.
Volkswagen made the decision to use the Common Rail technology in 2007 to implement a far more contemporary solution. As it turned out, this choice benefited these engines, which are distinguished by a significantly better operating environment. The variety of alternatives available has greatly grown over its predecessor; the new units have four valves per cylinder and can produce power ranging from 110 to 184 horsepower. The 2009 injection system’s earlier iterations were superseded by Common Rail engines.
The 2.0 TDI engine’s dependability may be better. Most issues begin to surface between 100,000 and 125,000 miles. There are many issues that are similar to those that plague the most recent diesel vehicles, but there are other issues that are unique to the 2.0 TDI variants. cylinder heads being shot in the 16-valve variant. Volkswagen is sure that it will address this issue before the end of 2006, although there are also newer vehicles with similar issue.
Another common problem with the 2.0 TDI is the oil pump, which occurs in both versions: in the version with the chain oil pump, the chain is stretched; in the version with the hexagonal shaft oil pump, the hexagonal shaft is rounded off. It is thought to be the root of the pump issue, which is also influenced by the motor shaft’s balance and generates the majority of the load. Lack of lubrication, igniting of the oil pressure bulb on the instrument panel, and rattling from the crankcase are signs of an oil pump failure (for chain version).
symptoms of a pump-nozzle injection engine, loss of engine power, and harsh engine operation. The most frequent issue is nozzle failure, which necessitates nozzle repair or replacement. There are two different kinds of injection units: Siemens and Bosch.
What should I look for in a used Audi A4 saloon?
The 2.0-liter diesel versions have a tendency to burn oil over time, and some owners depend solely on the oil warning light without checking the level. This is risky and can permanently harm the engine. Check the dipstick to see if the oil is low after consulting the service manual to see when it was last changed.
Reliability of Audi diesel engines
In conclusion, there are conflicting opinions about how reliable these engines are. However, the earlier versions had more issues. We would conclude that the older versions have been sufficiently adjusted to be trustworthy engines. Some of them have a 200,000-mile endurance limit, but they most certainly won’t live much longer. With these engines, regular maintenance is essential because, if neglected, the majority of them begin to have issues after 100,000 miles.
How far can a 2.0-liter diesel engine travel?
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.
Is the 2.0 TDI Audi A3 dependable?
No. Recent dependability studies have placed Audi very poorly, which is not encouraging. Additionally, the What Car? In comparison to competitors, Reliability Index estimates a rather high incidence of failures with this generation A3.

- DMAX Ltd. (A joint venture between Isuzu and General Motors) (A joint venture between Isuzu and General Motors)
- Detroit Diesel Corporation, etc. (located in Detroit, Michigan, USA).
Q: Which is better Duramax or Cummins?
The horsepower capacity of a vehicle engine is one of the widely used metrics to assess its superiority. Regardless of whether a vehicle is towing another vehicle, high horsepower promises quick and faster acceleration.
The most recent Cummins 24V Ram 6.7L diesel engine produces 400 horsepower compared to the 6.6L Duramax L5P’s approximately 445 horsepower. This is where Duramax outperforms Cummins. Both diesel engines, nevertheless, are among the best.
Q: What are the worst diesel engines?
Due to their failure to produce both the power needed by the cars and the necessary amount of horsepower for efficient and quick acceleration, some of the worst diesel engines ended up making the black list.
Some of the worst diesel engines you can imagine in the automotive business are the ones that follow:
- international DT VT-265 and VT-335 engines
- CAT 3116
- ISX Cummins
- engines from the vintage 2-stroke Detroit series 50, V-71, or V-92, etc.
Some of the above-mentioned engines worked properly when they were first produced (for example, the VT-265, and VT-335). When the manufacturers chose to change them from 6 to 4 cylinders, changing their power output, they started to perform poorly.
Q: What is the longest-lasting diesel engine?
The 5.9L Cummins 12-Valve 6BT diesel engine has the greatest lifespan. The engine has a million-mile lifespan and an exceptional 30 horsepower for quick acceleration. It also has a powerful P7100 injection pump and up to 440 ft-lbs of torque.
The Duramax and some other diesel engines aren’t even close to the Cummins when it comes to torque. They have a maximum torque of 1,000lb/ft.
You can’t go wrong with the Cummins 5.0L 12-Valve 6BT diesel engine if you require a long-lasting diesel engine.
Q: Why is Cummins the best diesel engine?
The best diesel engine, if you’re wondering, is a Cummins. Truck aficionados regard Cummins as one of the top diesel engines for pickup trucks for a reason.
One of the main producers of diesel engines for the automotive sector worldwide is Cummins Inc. Respected for the amount of torque and horsepower they produce, Cummins engines ensure quick acceleration on the road.
To be able to carry huge loads at any moment, work vehicles need to have a lot of horsepower and torque. The requisite horsepower and torque are precisely what Cummins diesel engines provide.
It makes sense why Cummins engines are known to as the torque king. In 2020, Cummins maintained its status as one of the top diesel engines and is modern.
Q: What diesel engine does Ford use?
6.7L Powerstroke engines are used to power contemporary Ford trucks. The engines used in Ford’s diesel-powered trucks are currently in their fourth generation. The majority of the diesel engines for Ford trucks were produced by Navistar International.
The 6.7 Liter V8 engine is Ford’s first officially produced power stroke diesel engine. Prior to the creation of this diesel engine, Ford had several Powerstroke models made by Navistar International (formerly known as International Navistar).
