Does BMW Use Diesel?

Despite the disadvantages, and with substantial advantages in mind, particularly in the area of fuel efficiency, BMW provides a variety of diesel models, including the 320d, X5 xDrive 35d, and 540d, which were introduced last year (2018). Despite the stigma that surrounds diesel engines, they remain dedicated to them. Unfortunately, many of these models are not accessible in the United States, but some are. The carmaker makes it plain that diesel engines will continue to be an important element of their powertrain offering in order to satisfy global carbon-dioxide emission targets. Those looking for the best fuel efficiency may consider equipping their next BMW with a diesel engine.

Why did BMW stop making diesel?

This choice is influenced by lower demand, stiffer restrictions, and a concentration on plug-in hybrids. If you want a new BMW with a diesel engine, you’d better hurry. After the 2018 model year, the German automaker is expected to stop selling diesel vehicles in the United States.

What years did BMW make a diesel?

Manufacturers from Europe have led the way in bringing modern clean diesels to the United States market, where diesel vehicles are widely accepted for their performance, efficiency, and lower CO2 emissions. Mercedes-Benz (M-B) is the automaker with the longest history, having introduced diesel vehicles to its lineup in 1968 with the 200D and 220D. The four-cylinder 200 D produced only 55 horsepower, allowing the automobile to accelerate from 0 to 62 mph in 28 seconds and reach a top speed of 81 mph.

Diesel passenger car sales climbed dramatically, reaching a high of 520,788 in 1981. General Motors produced 60 percent of the diesel vehicles. That amounted to 10% of GM’s total sales for the year. Diesels were a significant factor for other manufacturers. In the United States, they accounted for about 85% of Peugeot sales, 78 percent of Mercedes-Benz sales, 58 percent of Isuzu sales, and nearly half of Volkswagen sales. Audi, Volvo, and Datsun all sold diesel passenger cars in 1981.

Significant problems began to surface in GM diesel-powered automobiles shortly after that.

Crankshafts and blocks cracked prematurely. Critics said it was just a modified gasoline engine, and unhappy owners formed clubs and filed lawsuits. Tougher pollution requirements wreaked havoc on all diesel manufacturers. The price of gasoline began to fall, putting the final nail in the coffin of diesel. Diesel sales also decreased. GM, which had been so enthusiastic about diesels, stopped producing them in 1985.

The 524td, BMW’s first diesel, was introduced in the United States in 1985.

It was the world’s fastest and most powerful diesel car at the time.

Due to falling gasoline prices in the United States, customers lost interest in diesels and grew less worried about fuel efficiency around the mid-1980s.

As a result, the 524td was only produced for a few years, ending with the 1986 model year.

In the years afterwards, BMW’s engine development experts have improved a wide range of innovations, ensuring that they meet series production standards while enhancing power and performance while lowering fuel consumption and emissions. BMW, for example, debuted Digital Diesel Electronics in 1987, followed by BMW’s first diesel engine with an oxidation catalyst three years later.

BMW’s engine development specialists understood the potential of diesel to improve efficiency from the start. They concentrated on the distinct performance characteristics of diesel, resulting in a completely new concept of The Ultimate Driving Machine. Above all, they took use of the diesel engine’s ability to generate higher torque at low engine speeds.

As a result, the BMW diesel was able to quickly establish its own sporty character – both in everyday driving and on the racing track.

When a BMW 320d won the 24 Hours of Nürburgring in 1998, it became the first diesel-powered race car to win a 24-hour endurance race.

In the same year, BMW unveiled its first diesel engine with direct fuel injection, allowing for considerably more flexibility in power development. The exact fuel dose helps cut fuel consumption and optimize combustion in the process, resulting in even more smoothness and refinement. Given these characteristics, the BMW diesel was finally prepared for the luxury performance class, with the first V8 diesel engine with direct fuel injection debuting in the BMW 7 Series luxury sedan in 1999.

Common-rail direct fuel injection, Sequential Twin Turbo Technology, a maintenance-free diesel particulates filter, and BluePerformance are all in the works.

BMW made considerable – maybe revolutionary – development in the areas of injection technology and diesel turbocharging in the years that followed. Fuel was delivered into the combustion chambers at a pressure of up to 1,600 bar, or over 23,000 psi, as early as 2001 with the second generation of common-rail fuel injection. The BMW 535d was the first car to employ Sequential Twin Turbo Technology in an inline-six diesel engine in 2004.

BMW also released the second iteration of its diesel particulate filter, which is now standard on all diesel cars. The exhaust gas-cleaning unit is mounted directly on the exhaust manifold to achieve maximum efficiency as early as possible. The particulate filter is self-cleaning and regenerates itself by incinerating the diesel particles. This filtering feature operates at all engine speeds and loads, resulting in no loss of engine power or increased fuel consumption.

A number of four-cylinder and six-cylinder diesel engines are available in BMW’s current lineup. The aluminum crankcases of both the six- and four-cylinder engines help to greatly reduce the weight of these engines. The adoption of a cast iron crankcase (a much heavier material than aluminum) has practically eliminated a typical disadvantage of the diesel engine, which adds weight. The car’s agility and, as a result, the sports character of BMW’s diesel versions are improved by the weight reduction.

When comparing the first six-cylinder BMW diesel engines from 1983 to today’s most powerful diesel engines, it’s easy to see how far we’ve come.

Take a look at the following numbers and facts:

The inline-six engine’s maximum output has increased by 135 percent, while maximum torque has increased by even more remarkable 170 percent.

Despite this significant boost in power and muscle, the 3.0-liter engine with Sequential Twin Turbo Technology consumes 20% less fuel than diesel engines from 1983.

At the same time, thanks to a number of new technologies, exhaust emissions have been drastically decreased.

For example, a BMW diesel from the 2008 model year emits only 1% of the particle pollutants seen in the exhaust gas of a 1983 diesel model.

Even though media reports about diesel vehicles have been mostly positive, citing advantages in performance, efficiency, range, and, of course, lower GHG emissions and reduced use of fossil fuels, modern clean diesel technology has struggled to gain recognition as a viable alternative even though media reports about diesel vehicles have been mostly positive, citing advantages in performance, efficiency, range, and, of course, lower GHG emissions and reduced use of fossil fuels.

While consumer acceptance has lagged behind critical media approval, sales of the VW Jetta and BMW X5 xDrive35d have increased in the last two model years, indicating that opinions are shifting once again.

With the debut of two BMW Advanced Diesel models for the United States in 2009, the BMW Group provided more proof of its EfficientDynamics engineering philosophy. A 50-state emission compliant variant of BMW’s award-winning sequential-turbo 3.0 liter diesel engine is included in the 335d and X5 xDrive35d vehicles. This is BMW’s first performance-oriented Advanced Diesel engine in the North American model line, and it serves as the foundation for the most fuel-efficient internal-combustion car the company has ever marketed in the US.

The sequential-turbo 3.0 liter diesel engine produces 265 horsepower by combining a very small and a larger turbocharger with a novel intake arrangement.

The torque characteristics are even more amazing.

From 1100 to 4200 rpm, 80 percent of the torque is accessible.

At 1750 rpm, peak torque is 425 lbs-ft, which is nearly as much as BMW’s 6.0 liter V12.

The ensuing performance is just what a BMW aficionado would anticipate.

The 335d can sprint from zero to sixty miles per hour in six seconds flat, while the X5 xDrive35d can accomplish it in 6.9 seconds.

There are no other diesels in the United States that perform as well as these BMW Advanced Diesel variants.

This performance capability is complemented by excellent fuel economy.

The 335d’s EPA mileage estimates are 23 city and 36 highway, which are the highest statistics ever attained by a road-going BMW in the United States.

The X5 xDrive35d gets 19 mpg in the city and 26 mpg on the highway.

The X5 xDrive35d has a range of more than 580 miles between fill-ups, but the 335d has a range of about 560 miles between fill-ups.

While the 335d provides outstanding sports sedan driving performance and everyday versatility, the X5 xDrive35d provides the poise, control, and safety of a BMW Sports Activity Vehicle, as well as a 6,000-pound towing capability.

  • BMW Advanced Diesel car sales have been gradually increasing in recent months.
  • The X5 xDrive35d is the most forward-ordered car in the BMW fleet, accounting for 30% of total X5 sales thus far this year.
  • In the luxury sector, the X5 xDrive35d is the best-selling diesel (up 37 percent YTD).
  • While the 335d sells less than the X5 Diesel, it has had a 77 percent growth in sales year over year.

BMW’s Advanced Diesel with BluePerformance technology is part of the EfficientDynamics system of integrated technologies (ED). As a result, the majority of the company’s new vehicles are more efficient and cleaner than the previous generation, while also performing better. ActiveHybrid technology, electro-mobility in the context of “Project I and the usage of hydrogen as an energy source are also essential components of ED.

Today’s BMW Diesels have drastically enhanced power and performance, as well as fuel consumption and pollution levels, demonstrating the BMW EfficientDynamics principle in every way.

BMW diesel engines have helped to greatly reduce misgivings about a diesel engine’s acoustic qualities just by virtue of their refinement. In reality, strong demand for BMW diesel engines has helped the company gain market share not only in Europe, but also in other parts of the world. In 2009, a diesel engine powered no less than 63 percent of all new BMWs supplied to consumers in Europe.

While today’s diesel engines set an impressive standard for fuel efficiency and emissions, BMW Advanced Diesel engines go even further, setting a standard for torque and pulling power that a similar displacement gasoline engine could never match – all while using 25% less fuel on average than an equally powerful gasoline engine.

The first BMW Advanced Diesel with BluePerformance is especially well-suited to combine the driving characteristics and refinement of a luxury vehicle with the most current and stringent regulations for resource conservation and emissions reduction. The 3.0 liter inline-six diesel engine is one of the most fuel-efficient engines in its class, with great power and torque.

Advanced Diesel with BluePerformance includes an oxidation catalyst just downstream of the exhaust manifold, a diesel particle filter contained in the same unit, and a Selective Catalytic Reduction catalyst with urea injection to enhance emission management. This combination ensures effective reduction of nitric oxides (NOX) by way of a chemical reaction within the exhaust system begun by the injection of a modest quantity of urea known as Diesel Exhaust Fluid, in addition to filtering out even the tiniest particles from the flow of exhaust gases. The ammonia (NH3) produced in the SCR catalyst then transforms the nitric oxides (NO and NO2, respectively) in the exhaust gas into environmentally friendly nitrogen (N2) and water vapor (H2O).

BMW devised a two-tank system to bring SCR technology into the vehicle, ensuring convenient use of this new technology with all the benefits and convenience required by the consumer. A dosing pump injects the needed amount of Diesel Exhaust Fluid from the active tank (about 1.6 gallons in volume) in each occurrence. This active tank, as well as the dose pipelines, are heated because the DEF would freeze at 12oF.

The active tank is connected to a passive tank, which is a second reservoir. This passive tank provides a sufficient supply of DEF thanks to its enhanced capacity of about 4.5 gallons. The average range supplied by this supply capacity is usually enough to keep the tank system topped up only when the driver has to change the engine oil. As a result of the huge amount of DEF kept in the reservoir, the customer can drive for longer periods of time without having to change his or her service intervals. As a result, the driver enjoys the benefits of this ecologically beneficial emission technology throughout the duration of the vehicle’s life, generally without the need for extra service or trips to a BMW Center. Because all BMWs sold in the United States are covered by the BMW Maintenance Program, the DEF tanks will be refilled at no cost for the first four years or 50,000 miles.

DEF is transported from the active tank to the dosing valve, where it is atomized and injected into the exhaust system. The SCR mixer ensures that DEF is distributed evenly throughout the exhaust flow. In a process known as a selective catalytic reaction, the ammonia created in the hot exhaust flow acts as a reduction agent in the SCR catalyst, converting environmentally damaging nitric oxides into nitrogen and water vapor (SCR). The name of the specific SCR catalyst comes from this procedure.

BMW’s advanced engine management computer is in charge of controlling the SCR system. The concentration of NOX in the exhaust emissions is monitored by a nitric oxide sensor located downstream of the SCR catalyst.

The position and location of the DEF tank and refill port changes from model to model due to packing constraints. The active and passive tanks are located in the rear of the BMW 335d, whereas the active tank is located in the front right section of the engine compartment and the passive tank is located beneath the floor next to the transmission in the BMW X5 xDrive35d. The refill ports on both models are conveniently accessible, ensuring that if the need to replenish the DEF supply before a scheduled service visit arises, it may be done quickly and efficiently.

How do I know if my BMW is diesel?

By using the methods listed below, you may readily distinguish between gasoline and diesel vehicles. To be sure, try at least a couple of them.

The Unpleasant Sound

Compared to the smoother sounds of their petrol counterparts, diesel cars’ engines emit a distinct tractor-like sound. At idle, the sound is a rattling noise that becomes raspier as you drive. These days, however, programmed diesel automobiles do not generate such noises. This method can be used to identify vintage automobiles.

Check the Fuel Cap Label

A label on the inside of the fuel door should read ‘Diesel Fuel Only,’ ‘Gasoline Only,’ or something similar, indicating the type of fuel the automobile uses. Check the fuel filler neck, the car key, and the instrument bundle near the fuel gauge if nothing is present. The rental firm will usually place stickers in one or all of these locations to indicate the type of fuel used in the vehicle.

Find the Clue in the Model Name

It’s a simple technique to distinguish between gasoline and diesel vehicles. The letter ‘D’ is likely to appear in the model name of cars having a diesel engine. BMW 745d or Lexus IS 220d, for example. The letter ‘D’ signifies that these vehicles are powered by a diesel engine.

A badge with the model name is likely to be seen on the back of your car. If it starts with the letter ‘D,’ it’s a diesel engine.

Look at the Engine

The car’s engine architecture also reveals the sort of fuel it utilizes. Spark plugs are not used in diesel engines. The mass air flow sensors and the throttle body are missing on some earlier models.

Fitting Fuel Pump

If examining around the car and within the engine yields no results, the fuel pump may be your only hope. In comparison to the thicker, larger diameter of diesel pump nozzles, modern petrol cars feature a narrow opening. If you have to shove the nozzle into the fuel neck, don’t fill the tank.

The compact petrol pump nozzle will slot into the diesel car’s fuel filler neck, making it easy to put petrol in a diesel automobile. To avoid an accident like this, make sure the nozzle fits snugly into the filler neck. If the nozzle seems too tight or too loose, don’t fill up.

How do I know if my BMW is petrol or diesel?

How can I know if my automobile is a diesel or a petrol?

  • Keep an eye out for a sticker. Rental car firms frequently install stickers in various locations throughout the vehicle to indicate which fuel to use.

Do BMW diesels have problems?

Timing chain difficulties have caused a lot of damage to the BMW 320d 2.0 Diesel N47D20A and N47D20C engines, and the percentage of these engines with timing issues has been rather high. The timing chain is damaged by the crankshaft sprockets, which reduces the engine’s performance.

Due to the car’s inability to run for long periods of time, the timing chain will eventually fail. There are just two options: either replace the engine altogether or pay a high repair bill. In both cases, you will have to pay a significant amount of money. It’s only that a replacement is less expensive than a repair.

The 2.0D engines are also affected by a manufacturing problem of the crankshaft sprockets, according to Engine Trust, a company that specializes in BMW 320d engine replacements. Due to a manufacture fault during the engine’s manufacturing, the sprockets drive the chain to the pressure pump on the camshaft. This will force the chain to snap in half, resulting in significant engine damage.

A return spring issue affects these 320d 2.0 Diesel engine versions, causing the turbo wastegate to be fully or partially open. Due to a spring problem, the wastegate remains partially open, resulting in poor turbo regulation. It either damages or completely destroys the turbo engine.

BMW 520d 2.0 Diesel Engine Issues

The timing chain has also caused issues with the BMW 520d 2.0 Diesel N47D20A and N47D20C variants of the same model. These are likewise two-cylinder engines, similar to the BMW 320d 2.0 Diesel engines’ two-cylinder engines. When the timing chain fails, the engine will not start and will do catastrophic damage to both the engine and your wallet. However, several variations have been known to have a manufacturing flaw.

The timing chain is driven to the high pressure pump on the camshaft by the crankshaft sprockets that have been created. As a result of this, the chain wears out and either snaps or jumps. In both cases, the engine suffers significant damage.

The spring problem also affects the BMW 520d 2.0 Diesel N47D20A and the other N47D20C variations stated above, resulting in the turbo blowing up while the wastegate remains partially or fully open.

BMW X5 330D 3.0 Engine Problems

The BMW X5 330D 3.0 diesel N57D30A engine has been known to generate significantly more problems than the previous two automobile engines. This engine, along with the 330D 3.0 Diesel’s N57D30B and N57D30C engines, has been known to have major engine difficulties.

The timing chain of the BMW X5 330D 3.0 diesel engine is faulty. When the crankshaft sprockets in these engines are misaligned, they inflict serious damage to the timing chain and create a slew of engine difficulties.

If the timing chain is constantly damaged, it will not last long and will break down at any time. When the timing chain fails, its components may become jammed in other areas of the engine, resulting in significant repair or engine replacement costs for you.

Other issues with the BMW X5 330D 3.0 Diesel engine variations discussed above include a manufacturing flaw in the crankshaft sprockets. As a result of this manufacturing flaw, the sprockets drive the chain to the high-pressure pump on the crankshaft. This will damage the timing chain or cause it to snap in half, resulting in engine damage.

The spring placed in the turbo wastegate in the BMW X5 330D 3.0 Diesel models detailed above is also a concern. When the wastegate spring is compressed, exhaust gases are discharged, bypassing the turbine and regulating its speed.

Failure to maintain sufficient lubrication causes the turbo to blow up, forcing the wastegate to open entirely or partially. The spring is critical for properly opening and closing the wastegate, else the turbo will be destroyed.

The BMW X5 330D 3.0 Diesel M57D30 (306D3) and M57D30 (306D5) have been known to have issues with turbo and injector failure for a long time. The major cause is filthy oil or a lack of lubrication, which causes the turbo to fail catastrophically. Because of the turbo failure, the engine is no longer as powerful as it once was, and it is not operating at full capacity.

BMWs are stylish, costly, and extremely powerful automobiles. The German automaker is recognized for producing vehicles that are both elegant and long-lasting. However, some BMW engines have had more issues than most people realize. Many people may be surprised to learn that BMW engines have recently been plagued by major problems. BMW has a long way to go in terms of making them more robust.

How long will BMW diesel engines last?

Yes, diesel BMWs can outlast their gasoline-powered counterparts. Maintenance at the proper intervals, like with any other fuel-powered engine, will ensure the engine’s longevity. We discovered that diesel engines can travel between 250,000 and 300,000 kilometres.

Will BMW stop making diesel?

Along with the six-cylinder monster, BMW is phasing out the 1.5-liter three-cylinder engine that’s also used in a number of MINI Cooper D models.

Perhaps less shockingly, Froelich predicts that the company’s enormous six-liter V12 engine will follow suit.

“Given that we only produce a few thousand units each year and the thousands of euros it costs to make them compliant with higher emissions laws,” Froelich said, “the V12 may not have a future.”

According to TopGear magazine, BMW will continue to produce the V12 until at least 2023. However, if Froelich’s words are to be believed, that may be the last we hear of it.

For at least another 20 years, the German manufacturer hopes to continue producing its other four and six-cylinder diesel engines. There are also petrol variants available for an additional $30.

What is the best fuel for BMW?

BMW recommended that you use premium unleaded gasoline in all of your vehicles. That isn’t to suggest that your BMW won’t run on lower-grade fuel, but premium unleaded petrol will keep its quality over time, allowing you to constantly drive at peak performance.
