Power units BMW M57D30 first began to be installed on cars of the German concern in the distant 1998. They were designed to replace the outdated diesel M51. The M57D30 engine was completely built on the basis of its predecessor. The cylinder block was made of cast iron, but the cylinders themselves were increased in diameter to 84 millimeters. The M57D30 got its performance thanks to the installation of a crankshaft that provides 8.8 centimeters of piston stroke. The connecting rods were 13.5 centimeters long. Pistons were used with a height of 4.7 centimeters. Thanks to this, the M57D30 engine received almost three liters of working volume, and to be more precise, 2.93 liters.
M57D30, reviews of which you can read below, had an aluminum cylinder head, which provided for the installation of 24 valves. Inlet and exhaust valves had the same diameter – 26 millimeters. The valve stem had a diameter of 6 millimeters. The same components were used as on the M47 diesel.
The camshaft is driven by the timing chain, which has a long life, so the chain may not need to be replaced at all under normal use of the power unit.

Advantages
This motor features BMW’s innovative Common rail fuel injection system, and has a supercharger paired with an intercooler. The M57D30 uses a Garrett GTX, a good turbine with variable geometry. In order for the motor to meet environmental requirements and improve mixture formation as well as combustion, the powertrain’s intake manifold was equipped with swirl flaps that shut off one intake valve at low rpm. The EGR valve also raised the exhaust gas figures. A Bosch DDE4 was used to control the engine.
The year 2002 was marked by the beginning of production of an updated modification of the motor, which was named M57TUD30. This power unit was distinguished by an increased working volume of up to 3 liters. This was achieved thanks to the installation of a crankshaft capable of providing a piston stroke of 9 centimeters. This modification used a DDE5 control unit, as well as a Garrett GT2260V turbine.
M57TUD30 TOP – the most powerful modification, which was equipped with a pair of turbines with different size. BorgWarner KP39 and K26 turbochargers were used, capable of inflating up to 1.85 bar. The engine was controlled by a DDE6 ECU and the pistons had a compression ratio of 16.5. The M57TU2 first saw the world in 2005. These engines featured a lightweight cylinder block made of aluminum, an updated fuel injection system, larger intake valves and a cast iron exhaust manifold. A DDE6 was used for control. A Garrett GT2260VK turbine was used as a supercharger.
The previous powerful modification was replaced by the M57TU2D30 TOP version, which was controlled by a DDE7 unit. Installation of a pair of BorgWarner KP39 and K26 turbochargers allowed the engine to blow up to 1.98 bar.
Disadvantages
The problem that annoys all users of M47 engines has passed on to its big brother – vortex flaps, which very often break off and get into the engine, causing serious breakdowns. These flaps are better to cut out in advance and rewire the electronic control unit by plugs. The crankshaft damper can fail. A sign of such a breakdown may be the occurrence of extraneous noises and knocks. The problem can only be eliminated by replacing the unit.
On BMW M57D30 there is a situation when you removed the egr and lost traction, this is normal, as it requires the installation of updated software. But simply loss of power can be due to a crack in the exhaust manifold, which has to be replaced with a cast iron one. This malfunction is also accompanied by exhaust inside the car and the fact that the revs are constantly floating. The injectors on this engine are able to pass more than 100 thousand kilometers. Superchargers at all can provide good work for 400 thousand kilometers. True, you have to use only high-quality oil, otherwise you can harm the turbines, and you need to know how much oil to pour into the motor.
Sometimes there is a question about how to change the pump, as it can fail after 100 thousand kilometers of mileage.
With proper care, normal oil and high quality fuel, there are no major problems with this power unit and it can be considered quite reliable. Very careful attention should be paid to the choice of diesel fuel, otherwise you can damage the fuel system. If all norms are observed, it is possible to provide more than 500 thousand mileage without serious breakdowns.
Modifications
The M57D30 motor, problems with which almost never occurred, received a large number of modifications:
- M57D30O0 – produced from 1998 to 2003. Was the base powertrain, which was accompanied by a Garrett GT2556V turbine, which allowed to achieve a power of 184 horsepower with a torque of 390 Nm.
- M57D30O0 is a power unit produced from 2000 to 2004. The version was characterized by higher power, which was 193 horses with 410 Nm of torque.

Range Rover vogue M57D30 was equipped with this modification.
Tuning
M57D30, tuning is quite simple. M57D30 chip tuning can be further boosted by another 40 horsepower. The downpipe on the M57TU2 series can provide about 20 more horses. Power of 306d2 and 306d3 can be increased to 340 horsepower, and stage 3 will give the opportunity to get an additional 20 horsepower on top.
The M57D30 is often welded to E34, as these motors are perfectly suited for this body, allow you to provide optimal power, dynamics and driving characteristics. There are no special problems during the integration of the motor.
