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 only used 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 inside. 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.

Is the Volkswagen diesel a superior vehicle to the Volkswagen gas model?
Heavy-duty trucks must quickly reach highway speed, and torque is essential. Additionally, diesel engines outperform gas engines in terms of torque. Think about a diesel Volkswagen if you need extra power.
VW 2.0 diesel dependability
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.

The most dependable diesel engine manufacturer?
After many years, despite its high-tech competitors, the 7.3L Powerstroke is still recognized as the most dependable diesel engine. The joint venture between Ford and International Navistar (now Navistar International) produced this diesel engine.
Ford’s powerful, heavy trucks were designed to employ the 7.3L Powerstroke diesel engine. The technology (HEUI) used in the diesel engine’s design helped do away with the necessity for a separate injection pump.
High-pressure engine oil generated hydraulic pressure in each injector to forcefully inject low-pressure gasoline in place of the injection pump. The 7.3; Power Stroke was exceptional and powerful enough to handle loads because of the engine’s outstanding characteristics and specifications.
- Up to 920 lbs. dry weight
- Dates: 19942003
- 4.11 by 4.18 inches for the bore and stroke
- 7.3 L. of displacement
- OHV with two valves per cylinder as the valvetrain
- 275 horsepower with a maximum speed of 2,800 rpm.
- Price: from $10,000 and above
- V8 configuration
- 525 lb-ft of maximum torque @ 1,600 rpm.
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.
Why is TDI so reasonably priced?
In conclusion, these are excellent vehicles that are widely available for purchase and unaffected by the emissions fix. However, there’s more.
TDI vehicles currently on the market are selling for roughly 30% less than they otherwise would be, which is partially due to the uncertainty and negative attention surrounding the Dieselgate scandal as well as partially owing to the large number of bought-back cars that need to find new homes.
For instance, even though the sticker pricing for the Jetta Sportwagen and a comparably equipped GTI were relatively similar when the cars were new, the Sportwagen is currently selling for roughly $4000 to $5000 less.
When you consider that used Volkswagen TDI cars had some of the greatest resale values on the used automobile market before Dieselgate, the difference is even more striking.

What drawbacks are there to diesel engines?
You should consider each fuel’s features when choosing whether to use gasoline, diesel, or an alternative fuel for your future vehicle to determine which is best for your driving requirements, financial situation, and environmental concerns. Despite efforts to minimize air pollution making the future of diesel appear questionable, there are still some advantages to purchasing a diesel vehicle. These benefits consist of:
- Performance. Due to their higher low-speed torque than gasoline vehicles, diesel vehicles are best coupled with automatic transmissions and are therefore perfect for highway driving and lengthy commutes.
- fuel economy. In the long run, diesel cars are more cost-effective than petrol cars because they typically use 15-20% less fuel.
- emissions of CO2. Although diesel fuel has a slightly higher carbon content per litre than gasoline, overall CO2 emissions from diesel vehicles are often lower than those from gasoline vehicles.
The main complaint against diesel vehicles is their emissions because they are known to emit dangerous pollutants like carbon monoxide, nitrous oxides, and particulate matter (CO). All cars with combustion engines, including hybrid and gasoline models, release harmful pollutants, but diesel models typically produce 11.5 times more NOx than gasoline counterparts.
The diesel particulate filter (DPF), which can eventually become clogged by exhaust soot, is another recurring problem. Because of the evidence that this soot aggravates asthma and other respiratory diseases, new MOT regulations state that any vehicles with a DPF that emits visible smoke or exhibits signs of manipulation will not pass. Additional drawbacks of diesel include:
- cost increases Diesel is more expensive to purchase at the pump than gasoline, and a diesel car’s greater purchase price may result in higher insurance rates. Taxes on new diesel vehicles are also higher.
- driving knowledge. Due to their high running pressure, diesel engines often produce more noise than gasoline ones. Recent improvements have, however, been made to lessen this on later models.
So, is buying a diesel automobile a good idea? Diesel vehicles are best suited for drivers who log more than 15,000 miles annually, but if you don’t log many miles, it might be more sensible to look at alternatives. Consider looking at hybrid or electric automobiles if you’re searching for a car that can provide a long-term investment, cheaper upfront expenditures, and a less carbon footprint.
Why did VW’s diesel vehicles disappear?
The majority, if not all, of the products we offer here come from partners who pay us. This could affect the goods we write about, as well as where and how they appear on a page. However, this has little impact on how we evaluate things. Our opinions are our own. Here is a list of our partners, along with information on how we get paid.
The restored diesel vehicles are slowly making their way back onto the market as fury over the Volkswagen emissions-cheating scandal subsides, and bargain hunters might want to snag them.
Following the discovery that around 590,000 diesel vehicles had been modified to pass emissions tests, Volkswagen was ordered to either buy back or fix those vehicles in 2015. The diesel vehicles, which were produced by Volkswagen, Porsche, and Audi between model years 2009 and 2016, have been fixed to actually comply with emissions regulations and are now being offered, primarily through Volkswagen dealers, with improved warranties.
