Finding out what type of engine is in front of you and whose automobile it belongs to will be quicker and easier if you comprehend the logic behind the labels used on engines.
BMW engines are identified by a sequence of numbers and letters that correspond to the engine’s technical specifications. This set may appear to have no logic and that the numbers are random at first glance. Contrary to popular belief, the VIN Number (also known as the vehicle identification number) is used by manufacturers to identify the version of a vehicle it is.
The upper-left corner of the tables below shows an example of the engine code. The symbol whose meaning is clear from this table is marked in red.

Identification of the engine numbers’ shape and appearance
The 5-character vin engine code and the actual engine numbers make up the engine N. (8 alphanumeric characters).
On more recent models, everything might be on a single line. The engine code matches the engine designation on the factory plate exactly (identification plate).
What is the BMW x5 engine code?
Plugging a scan tool into your car’s OBD II diagnostic port is the only way to find out why your check engine light is on. The set fault code or trouble codes will then be shown by the scan tool. The issue code and a one-line description of the code are typically displayed by scan tools.
How do I read the engine number on my BMW?
The N54B30 was mentioned previously. With regard to the model names we were describing, this code didn’t make sense. That is so because it is not a model name for a BMW. In actuality, it is an engine code, and each digit stands for a distinct component of the engine.
The initial letter, an N, stands for the family of engines that BMW uses. It will be one of the following six: M, N, B, S, P, or W. The W is the only one not built by BMW. The M range of engines was produced up to 2001, and the N range later. Modular engines called B engines have been developed since 2013. P engines are racing engines for motorsport, while S engines are production engines for motorsport. W is a category for outside engine providers.
The first number, the second component of the BMW engine code, can alternatively be one of the following six: 3, 4, 5, 6, 7, or 8. These show how many cylinders there are.
The engine variety is indicated by the third component of the code, the second number. Up to ten reasonably significant alterations, with 0 representing the original, are possible for the engine (marked as 1-9 in the code).
The last two figures represent the engine size multiplied by 10. Thus, the N54B30 from our earlier example would have a 3.0L engine.
Our BMW engine code’s optional addendum “TU,” which stands for “technical upgrade,” makes up the sixth component. These improvements are not as significant as engine variations and do not necessitate a new numerical categorization for the engine. Consider the iPhone 6 and iPhone 6s as the same model, but with Siri on one and not the other.

How do BMW engine names function?
In order to distinguish engines throughout engineering and production, automakers frequently give them internal nomenclature designations. Typically, they are just a list of letters and numbers that the average consumer cannot understand. But as Engineering Explained’s Jason Fenske notes in his most recent video, these codes typically include a wealth of information. BMW is a perfect example because it has been calling its lineup of engines the same way for decades. Here is a guide to understanding BMW engine code names.
I’ll give you an example. The S63B44T4 engine in the 2018 M5 is a reliable one. Here is the meaning of all those letters and digits.
The first letter indicates the “engine family” that this powerplant belongs to. In this instance, “S” stands for an engine created by BMW’s M division. Given that the engine is from an M5, this makes sense. The majority of standard, non-M BMW engines have a “N” designation if they were created after 2001, and a “B” designation for those created after 2013. If a BMW engine has a “W,” it was not produced by BMW but rather by an outside supplier.
6: The second character is a number that denotes how many cylinders the engine has. Don’t be deceived; occasionally, the digit doesn’t match the number of cylinders. For instance, this “6” actually denotes a V8 engine. Engines with three or four cylinders are designated as 3 or 4, accordingly. Here, the numbers 7 and 8 designate V12 and V10 engines, respectively.
The engine has undergone three upgrades, as shown by the third character. For instance, if this number were “0,” the original design would have been indicated. The “3” above denotes that this engine has three enhanced features, such as sequential turbos or direct injection.
B: The engine’s fuel type and whether it is positioned longitudinally or transversely in the vehicle are indicated by the fourth character. The “B” in this case indicates that it is positioned longitudinally and runs on gasoline. The engine would run on gasoline and be positioned transversely if it had a “A” designation. Diesel engines are denoted by letters “C” and “D,” while electric motors are denoted by letter “E.”
44: The displacement is represented by these two digits. Here, the “44” refers to 4.4 liters. This would be a 5.0-liter engine if it were to say “50.”
T: The engine’s “performance class” is indicated by this character. From lowest (K), lower (U), middle (M), upper (O), top (T), and super are the options (S). Ironically, this engine is in the second-highest category, which is the top class.
4: The very final character stands for the number of redesigns the engine has undergone during the course of its existence. It would be a new engine that has not yet been changed if this number were “0.” The engine in question is in its fifth generation and has had four modifications, as indicated by the “4”.
TU: The final two characters of some older engines are “TU,” which stands for “technical upgrade.” The engine has changed significantly from the previous edition, which is exactly what it sounds like.
Without a scanner, how do you read BMW error codes?
While turning the ignition key ON, press the Trip and Reset buttons on the odometer. Release the odometer Reset and Trip buttons after turning the key to the ON position to see if the Diagnostic Trouble Code, or DTC, shows up on the odometer display.
You’ve generated a diagnostic trouble code without a code scanner if the error code appears. Make a note of each fault code and look up the DTC definitions in your manual.
Which M47-powered BMW models are available?
Straight-4 diesel engines, such the BMW M47 and Rover Group M47R, are used. BMW produced variations between 1998 and 2007. Throughout the M47’s lifespan, BMW progressively included high-pressure common rail fuel injection systems.
What engine do I have, and how do I know?
“The VIN, which can be located in the owner’s manual or on the engine, will tell you what kind of engine your automobile has. The engine information can be found in the eighth digit.”
The VIN, which may be found in the owner’s manual or beneath the hood, makes it simple to determine what kind of engine is in your car. In most situations, the front of the dashboard on the driver’s side will also display the VIN. The eighth character of a VIN’s 17 digits gives details about your car’s engine. Find out what kind of engine your automobile has by deciphering it. You may find out what kind of engine your model has by conducting an internet search using the precise model, year of production, and trim level of your automobile.
The arrangement of an engine’s cylinders determines how car engines are classified:
- Cylinders in straight engines are arranged in a single row that runs parallel to the vehicle. They are typically used for saloon-style vehicles.
- The most popular type is an inline engine, which is frequently utilized in compact family vehicles like hatchbacks. Similar to the straight kind, but at a right angle to the automobile, they feature a row of cylinders organized in the engine compartment, allowing parts like the radiator, battery, and cooling system to be easily fitted around the sides.
- When viewed from the front, the cylinders of an engine with a V configuration are positioned at an angle to one another. Supercars and other high-end vehicles are better off with this configuration.
- Cylinders are arranged horizontally in two lines, pointing outwards, in a flat engine architecture. Even though this type of engine is less frequently employed than other designs, sports cars can handle more comfortably thanks to its lower center of gravity.
Engines are further divided into three categories: GDI (Gasoline Direct Injection), MPI (Multi Point Injection), and CRDI based on the fuel injection technology (Common Rail Direct Injection).
- The most popular gasoline engine technology, GDI, raises the efficiency of gasoline engines by sprinkling fuel directly into the combustion chamber. This kind of technology is more powerful and fuel-efficient than other gasoline engines, but it is also more expensive and noisy and vibrational than those engines.
- In comparison to GDI, MPI is less powerful and fuel-efficient, but it also offers better longevity and less vibration and noise.
- Diesel engines use CRDI, which offers a high combustion rate, minimal emissions, and increased engine power.
Which engine code do you have?
The year, make, and model of your car are always requested at auto parts retailers. However, they also require information regarding your engine. Don’t know exactly what’s inside or what year it is? VIN numbers can be used to determine engine size. On the driver’s side of your windshield, locate it in the lowest corner. Your vehicle identifying number, or VIN, can be used to determine the size of your engine.
The model year is indicated by the tenth number from the left, while the engine codes are indicated by the eighth number. You only need to mention those two characters to the store clerk to get started.
What do the numbers in a BMW VIN stand for?
The VIN code’s letter or number placement provides crucial details about your BMW’s production history, including where and when it was built, the type of engine it has, the model or series it belongs to, and numerous features and equipment.
