It goes without saying that BMW series, models, and model years vary from one another in terms of safety features, engine size, body and chassis style, transmission type, and OEM equipment they are equipped with. The current BMW model lineup is divided into 18 different series, some of which are updated iterations of their vintage forebears. However, there is much more to it than that, and we confess it can be a little perplexing given the overlap in BMW model naming.
- Before you purchase the car of your dreams, you should be thoroughly informed on the qualities of a particular model. A car can feel like a second home to some of us, and you should experience this when driving.
- After choosing to purchase a BMW, you must keep in mind that it will eventually need repairs or replacement parts. Regardless of whether you choose a physical location or an online store, you will undoubtedly be questioned about your series, model, and year of production.
You’ll ultimately feel the desire to improve your BMW, we’re pretty confident of that. Understanding your model and consequently original OEM gear is crucial for that.

Codes for BMW Engine Identification
Since 1978, all BMW engines sold in the US are covered by this information. On the engine block are codes that can be used to determine the engine’s displacement size, country version, fuel system, revision state, and serial number.
The engine block may have a variety of codes imprinted into it. These symbols stand for:
1. ENGINE CODE AND NUMBER:
Engine No. :
An eight-digit engine number, made up of two sets of four digits, will be assigned to a series production engine. Information on the assembly line and the serial number of the engines produced each day is contained in the first block’s first four digits. The factory code and manufacturing day are displayed in the second block.
An engine designation code is stamped in series manufacturing engines in addition to the eight-digit engine number for model identification. With the aid of Chart 1, these numerals can be decoded.
Note: The codes for new/remanufactured engines obtained from the parts department are different from those for production engines and should not be confused with them. This code (see list below) contains details on the nation version, change status, fuel system, and number of cylinders for engines fitted during production:
The information for the remanufactured engine is now die-stamped in the same location as for new engine identification after the digits for the original engine data were ground off.
Similar to engines in series production, the 8-digit engine number is made up of 2 blocks of 4 numbers, however they represent distinct information:
- Information on the daily production of engines is given in the first block of four digits.
- The month and year of production are also included in the second block, along with a code for either a new or remanufactured engine.

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.

One of the most popular and successful inline-6 engines made by BMW is the N52. The N52 was primarily used in the E90 325i, 328i, and 330i as well as the E60 525i and 528i models.
