BMW N57D30, N57D30S1, N57D30TOP engines
The production of the next generation of 6-cylinder turbocharged diesel engines - N57 (N57D30) from Steyr Plant, began in 2008. Compliant with all Euro-5 standards, the N57 has replaced the beloved M57 - repeatedly awarded at international competitions and one of the best in the BMW turbodiesel line.
The N57D30 received a closed aluminum BC, inside which a forged crankshaft with a piston stroke of 90 mm (whose height is 47 mm) was installed, which made it possible to achieve as much as 3 liters of volume.
The cylinder block inherited from its predecessor an aluminum cylinder head, under which two camshafts and 4 valves per cylinder are hidden. The diameter of the valves at the inlet and outlet: 27.2 and 24.6 mm, respectively. Valves have legs 5 mm thick.
A characteristic feature of the timing chain drives in the N57 internal combustion engine, as in the N47, is that the chain is located at the rear of the installation. This was done in order to reduce the risks of pedestrians in case of emergency.
The N57D30 units are equipped with: diesel fuel supply technology - Common Rail 3; High pressure fuel pump CP4.1 from Bosh; supercharger Garrett GTB2260VK 1.65 bar (in some modifications, double or triple models of turbocharging are installed), and, of course, an intercooler.
Also installed in the N57D30 are intake swirl flaps, EGR, and a Bosch electronic unit with DDE firmware version 7.3.
Simultaneously with the 6-cylinder N57, a smaller copy of it was produced - N47 with 4 cylinders. In addition to the absence of a pair of cylinders, these engines were distinguished by turbochargers, as well as intake and exhaust systems.
Since 2015, the N57 has been replaced by the B57.

Modifications
- The N57D30O0 is the first Upper Performance N57 with 245 hp. and 520-540 Nm.
- N57D30U0 - Lower performance version of N57 with 204 hp, 450 Nm, and Garrett GTB2260VK. It was this modification that served as the basis for N
- N57D30T0 - N57 of the highest (Top) performance class with 209-306 hp and 600 Nm. The first BMWs with the N57D30TOP appeared in 2009. The units were equipped with a modified exhaust, piezoelectric injectors and a BiTurbo boost system (with K26 and BV40 from BorgWarner), where the second stage is a supercharger with variable geometry, which allows you to create a pressure of 2.05 bar. The N57D30TOP is controlled by a Bosch box with DDE firmware version 7.31.

Advantages and problems of N57D30
Pros:
- Turbo systems
- Common Rail
- High potential for tuning
Cons:
- crankshaft damper
- Intake flap problems
- Injectors with piezoelectric drive
Extraneous noises in the N57D30 indicate a broken crankshaft damper, which usually happens already at 100 thousand kilometers. After another hundred thousand, an unnatural sound in the rear of the unit indicates a possible need to replace the timing chain. An additional problem here is the operation of dismantling the power plant, because the drive itself is located at the back. Chain resource - more than 200 thousand km.
Unlike the units of the M family, the dampers in the N57D30 cannot get into the internal combustion engine, but they can become so heavily covered with coke that they stop working altogether, which is why the motor will constantly give errors.
The EGR valve also needs to be cleaned, because often, already at 100 thousand kilometers, it can be thoroughly clogged with dirt. To avoid the above problems, it is better to simply put plugs on the dampers and EGR.
In order for the motor to work extremely adequately after that, you will have to reflash the control unit.
The resource of turbines in BMW N57D30 engines is about 200 thousand km, but usually even more. In order for the power unit to work as long as possible, you should not save on the quality of the oil and it is better to use technical fluids recommended by the manufacturer, as well as service the engine in a timely manner and refuel it with proven fuel. Then the resource of the N57D30 engines themselves can significantly exceed the 300 thousand km declared by the manufacturer.
Tuning N57D30
Conventional N57D30s (N57D30U0 and N57D30O0) with a single turbocharger can achieve up to 300 hp with the help of chip tuning, and with a downpipe their power can reach up to 320 hp. The N57D30T1 units in this case add more than 10-15 hp. By the way, the above ICEs with 204 and 245 hp. the most popular for tuning.
The power of the N57D30TOP with two superchargers with just one flashing of the control unit and with a downpipe is tuned up to 360-380 hp.
Perhaps the most flawless of the entire N57 family is the N57D30S1 diesel unit with a Tri-Turboged injection system, after chip tuning and with a downpipe, it can develop power up to 440 hp. and 840 Nm.
