BMW refers to its vehicles with all-wheel drive as an option rather than the more common rear-wheel drive under the moniker xDrive. In order to improve traction and provide the driver with superior control in more difficult driving circumstances, consider the 328i xDrive as an example. This vehicle can transfer power to both the front and rear wheels.
All-wheel drive has typically been associated with less environmentally friendly vehicles like SUVs, however your BMW can come in both xDrive and SULEV versions. Some buyers of the xDrive who discover it to be a SULEV may decide to modify it to turn it into a more potent type. They might not consider a SULEV BMW to be a true performance BMW.
The N51 SULEV is now nearly identical to the N52 in many ways because to technological advancements and general improvements. BMW SULEV engines are by definition unable to match the performance of the M4 or X5M engines, but those bearing the M designation are designed for performance on the racetrack.
To ensure that enough of BMW’s range can comply with the increasingly stringent emissions regulations and prevent the imposition of costly government fines, a SULEV engine is designed. Therefore, SULEV vehicles are a crucial component of any current lineup for a performance brand like BMW.

Exhaust
SULEV vehicles have completely different exhaust systems than conventional vehicles. BMW went ahead and added a catalytic converter to the exhaust manifold’s ultimate end. They’ve also added dual downstream cats and upstream oxygen sensors to some vehicles, including the E46 3-series.
These automobiles’ cats also need to warm up before they can perform at their best. When the entire system reaches the ideal operating temperature, they are designed to burn the most remaining particles.
Which States Offer N51 BMWs for Sale?
The LEV II Standards, which have since been adopted by additional states, include LEV (Low Emissions Vehicle), ULEV (Ultra Low Emissions Vehicle), SULEV (Super Ultra Low Emissions Vehicle), and PZEV (Partial Zero Emission Vehicle). Arizona, Connecticut, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New Mexico, New York, Oregon, Pennsylvania, Rhode Island, Vermont, Washington State, and Washington, D.C. are a few of these.
Your E9x 3-Series or another BMW generally powered by a N52 engine is probably powered by a N51 if it was acquired in one of these states.
What does SULEV on a BMW mean?
A U.S. categorization for passenger car emissions is super ultra-low emissions vehicle (SULEV). In order to qualify, a vehicle must emit 90% fewer emissions than the typical gasoline-powered car. The SULEV standard is more stringent than the standards for LEVs and ULEVs, but it is not as harsh as the PZEVs (partial zero-emissions vehicles), which satisfy the SULEV level for tailpipe emissions but have zero evaporative emissions rather than reduced ones. Japan additionally classifies vehicles as SU-LEVs if they exhibit a 75% reduction in emissions compared to the 2005 emissions criteria. [More information required]
Is every BMW a SULEV?
Although almost all BMWs are LEVs (Low Emission Vehicles), the whole BMW model line is required by law to fulfill certain low emissions objectives. BMW has special SULEV variants in order to increase their average while selling high-performance vehicles like the M5 and X5M.
How can I determine if my BMW is a SULEV?
It has actually gotten harder to tell what’s inside the hood now that many SULEV cars have the N51 and others bear the N52. It was simpler to identify the engines on earlier models that used the M54 and M56 SULEV. There were important visual cues, especially on the valve covers. On the other hand, the N51 SULEV vehicles and N52 engines have extremely similar appearances.
If you want to be sure, you can check the label mentioned above beneath the hood. If it says SULEV, then the engine is the N51; if it says LEV, then the engine is the N52. There are further methods, such as checking your BMW car identification number (VIN). The engine type and attributes are indicated by the numbers 4 through 8 in this lengthy number. The VIN can be found in numerous locations under the hood as well as on the driver’s side of the dashboard, which can be accessed through the windshield.
Hopefully, the SULEV requirements will enable your BMW to contribute to the solution rather than the issue of the environment. To determine whether you are a low emission vehicle or a super-low emission vehicle, look at the label beneath the hood.
BMW SULEV dependability
Between 2004 and 2015, the N52 replaced the wildly successful M54 and drove a number of BMW vehicles. It had a less well-known sister called the N51, despite becoming one of the most dependable and well-liked inline-six engines that BMW has ever produced.
It’s interesting to note that the N51 and N52 are almost identical, powering the same vehicles and being offered at the same time. In light of this, why did BMW create two versions of the same engine?
Are BMW SULEV prices higher?
However, it’s not so straightforward because there are other factors at play besides just the higher cost of acquisition. The SULEV/PZEV automobiles are more expensive to make and to fix. The components of “California emissions” are highly developed, intricate, and interrelated. For instance, the gasoline tank on a 2013 BMW 128i SULEV is hermetically sealed.
What is protected by the BMW SULEV warranty?
Previous repairs covered by the warranty included the replacement of the valve cover, each of the six coils, the fuel pump, the gasoline tank, and the fuel line. Recall that the SULEV warranty has two parts: one that covers the list of components and one that protects you in the event that an emissions test is unsuccessful.
What model of BMW has a N52 engine?
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. It was also used in a number of other vehicles, such the 128i, X1, and Z4, to name a few. From 2004 until 2015, the N52 was manufactured before being superseded by the turbocharged N20 engine. The M54, which was utilized in a number of E36, E39, and E46 models, was replaced by this model.
BMW was able to refine several parts of the engine during the course of manufacture thanks to the lengthy production history. Even top 10 best engines awards were given to the engine in 2006 and 2007. The N52 still experiences a good number of typical dependability issues, though. We’re going to talk about the top 7 engine problems that the N52 has.
The N52 has proven to be more dependable than its larger sibling, the N54, thanks to the engine design. Drivers of the N52 won’t have to worry about these two typical N54 problems because the N52 lacks an HPFP or direct injection. You may read our tutorial on N54 engine issues to compare the two as well!
What kind of engine powers a 2007 BMW 328xi?
The 3.0-liter inline-six cylinder engine that powers the 328i and 328xi models produces 230 horsepower. With a manual transmission, the manufacturer estimates that this engine can go from 0 to 60 miles per hour in 6.3 seconds with 200 pound-feet of torque.
Which motor powers my BMW 328i?
The BMW N52 engine’s specifications for the E90 and E92 328i are as follows:
The 3.0L inline-6 N52 engine of the 328i is naturally aspirated. To assist keep weight off the front axle, it incorporates a block made of lightweight magnesium and aluminum. Additionally made of aluminum, the head has 24 DOHC valves. Electronic throttle control, double-VANOS, and valvetronic are features of the BMW N52 328i engines. Better performance and fuel efficiency are delivered thanks to all of this technology.
What kind of motor powers the 2011 BMW 328i?
The 3.0-liter inline-6 engine in the BMW 328i sedan ($33,150) produces 230 horsepower. With the 328i xDrive sedan’s permanent all-wheel drive ($35,150), xDrive is added. Standard transmissions include a 6-speed manual, and most models may be ordered with a 6-speed Steptronic automatic for $1,375.
My BMW has a N51 or N52?
From 2006 to 2015, the engines were put into a wide range of various BMW automobiles. They can be found in the Z and X series, as well as the 1, 3, and 5 Series. Being aware of the type of displacement you’re dealing with is one simple technique to identify which engine you don’t have. N51 was only offered as a 3-liter engine, hence any inline-six of this generation that is 2.5 liters will be N52.
Following that, the following are some of the key variations between the two engines:
- Both the N52 and the N51 use aluminum cylinder heads, but the N51’s is unique due to changes made to the combustion chamber to comply with SULEV regulations. They cannot be switched out.
- Cylinder Head Cover: The cylinder head cover on the N51 is made of plastic and has integrated crankcase ventilation; the one on the N52 is made of magnesium.
- External crankcase vent valve with cyclone separator is a part of the N52’s crankcase ventilation system. The N51 contains an integrated vent valve, a labyrinth, and cyclone oil separation, as was already noted.
- On more powerful variants of the N52, the intake manifold is made of plastic and has a 3-stage DISA valve. The 3-stage DISA unit on N51 is utilized to account for various compressions.
- Piston/compression Ratio: For N52, this ratio is 10.7:1, but for N51, it is 10:1.
- The N51 utilizes a digital hot film meter, whereas the N52 features an analog version.
The problem is that despite all of these distinctions, it’s impossible to tell these engines apart by just opening the hood. Not like the M56 and M54 generations, for example. You could immediately distinguish the M56 SULEV from the M54 thanks to aesthetic differences.
But there is a solution. Examining the car emissions plate under the hood is the quickest way to figure out which engine you’re working with. The pertinent information can be found in the third row, on the left side of the plate. The N51 has a SULEV tag, but the N52 will be labeled as an LEV.
What are some typical BMW issues?
Some BMW owners have complained about issues with the heater core and coolant system in their cars. Frequently, the automobile overheating or not producing enough heat is the first sign of a coolant system issue. A sweet-smelling smell coming from the heater, which is the smell of coolant leaking, is another sign of coolant issues. If any problems develop, make sure to take the car to a dependable Portland auto repair facility. Nobody wants to be stranded in the middle of a cold Oregon winter without a working heater!
There are also known issues with the cooling system. The typical lifespan of a BMW coolant system is 80,000 to 120,000 miles. Maintaining routine maintenance is the best approach to avoid problems with the coolant system.
How many kilometers can a BMW 328i travel?
But how far is a BMW 3 Series capable of traveling? When maintained properly, you can anticipate your 3 Series to endure between 200,000 and 250,000 kilometres.
How far do BMWs travel before problems arise?
Although we think BMWs are dependable vehicles, there are a few main problems that affect the vast majority of BMW vehicles and BMW engines. A number of these issues begin to surface between 80,000 and 120,000 miles. Conveniently, there are a ton of used BMWs available that are close to this mileage and are considerably less expensive initially. Some customers purchase these vehicles without being aware of the problems, and they rightly become angry when they receive $1,000 maintenance bills soon after purchasing their BMW. A few things to watch out for are as follows:
- Electricity Problems
- Oil Spills
- Probleme with dem Kühlsystem
This is not a comprehensive list, and some specific BMW models might have additional frequent problems while other models might not have any of the aforementioned frequent problems. However, the most well-known and frequent difficulties are oil leaks, cooling system problems, and electrical problems.
