BMW B47d20 Engine FAQ

General Engine Information

Beginning in 2007 and through until 2017, this engine was manufactured. The cylinder block's primary material was aluminum. This engine naturally has a diesel personality. For a very long time, no one has been startled by its row of four cylinders and the four valves that each cylinder has. Here, the piston has a 90 millimeter stroke. The cylinders' diameter is once again 84 millimeters. The compression ratio was extremely high and ended at 16.5 percent. The engine has a normal 2 liter capacity. It produces between 116 and 184 horsepower at 4000 rpm. However, the power rises to 184–218 horsepower at 4400 rpm. At 1750-2500 rpm, the maximum torque varies between 260 and 300 N * m. It will be at the level of 380 N * m between 1750 and 2750 rpm. Its value changes to 350 N * m between 1750 and 3000 rpm. It has a maximum torque of 400 N * m at 2000 to 2250 rpm. Additionally, only at 1500–2500 rpm is the maximum value of 450 N*m set. Environmental regulations Euro 5 and Euro 6 apply to the engine. In this variation, many turbo compressors might be employed. The gadget will be 149 kilos in weight. On the highway, it will use 4.1 liters of fuel, on mixed terrain 4.8 liters, and in the city roughly 6 liters. 700 grams of oil are transported every 1000 kilometers. The engine should be lubricated with 0W-40, 0W-30, 5W-40, and 5W-30. The machine has around 5.2 liters of oil. After 7 or 8 thousand kilometers, it is worthwhile to replace it. Here, the comfortable temperature is 90 degrees. The resource has undergone practical testing, and its worth comes from 250 000 kilometers. The engine may be tuned to produce more than 250 horsepower.

This diesel engine first emerged in 2007. The cylinder block was now mostly made of aluminum. On the building, two balancing shafts and cast-iron sleeves could also be seen. A forged crankshaft and tiny connecting rods were located within. On top was a 16-valve aluminum head with two camshafts mounted. The vehicle boasts an exterior intercooler, the most recent injection system, and turbo boost. Initially, the turbine's geometry could be altered. There is a chain running the length of the timing drive, which is behind the motor. This circuit's resource is calculated for the whole time the motor is running. However, its shelf life and durability are pitiful. The purpose of the separate circulation valve is to expel gases. The vehicle's revitalization was the goal of the two flywheel masses and the most recent control unit. Defects The motor's rear may be heard making noise. This is the most frequent issue, and a stretched timing chain is often to blame. You need to replace it after roughly 100000 kilometers in most cases. In order to prevent the equipment from developing new issues, you must update it quickly. Because the chain is behind the engine and cannot be seen, it must be removed before replacement. Additionally, extra noises might be brought on by crankshaft dampers, whose resource is comparable and which has to be adjusted promptly. The whirlwind-shaped dampers are unable to enter the engine. As it works, the USR system gradually coats them with soot, which might have devastating effects. As a result, it's important to close the valves and use the manifold to clean the dampers. Drivers also install plugs. To avoid having to perform all of this work later, you may also flash the block at first. The fact that fractures develop between the cylinders causes the engine to heat up as well. In this situation, welding is not always beneficial, but the replacement will not be inexpensive at all. About 200 thousand kilometers' worth of turbines are available, although sometimes there are more. Their shelf life may be extended to 300,000 kilometers if maintenance is done on schedule. Although regular and frequent oil changes are required, it is advised to only use original oil and to utilize premium gasoline. Additionally, you shouldn't drive the automobile at the limit consistently.

Chip Tuning

Modern firmware must be installed in order to boost the motor's power. Some versions of machines and units are capable of swinging up to 210 or even 220 horsepower thanks to the firmware's addition of 35 to 50 horsepower. Thanks to CHIP tuning, the engine of the highest BMW series can produce 240–250 horsepower. Engines with the lowest names may be boosted to a maximum of 185 or 200 horsepower. Some models feature downpipes that can produce up to 230 horsepower and firmware that goes up to 215. The finest motor is capable of 249 horsepower and more. Additionally, 280 horsepower may be attained if a downpipe is installed.


The B47D20K0, which was manufactured from 2007 to 2012, is the least powerful kind. It features a turbine and produces 116 horsepower at 4000 rpm and 260 N* m of torque. The motor is set to 116 or 316 degrees. Production of U0 lasted from 2007 until 2013. It produces 243 horsepower at 4000 rpm and 300 Nm of torque between 1750 and 2750 rpm. The turbocharger and ECU aid in the correct operation of the engine, and the boost has a one and a half bar pressure. Furthermore, solenoid-equipped injectors exist. Applying 118d, 318d, X1, and X3 settings. The O0 has 177 horsepower at 4000 rpm and was also manufactured from 2007 to 2013. Here, the torque is 340 N * m between 1750 and 3000 rpm. With 1.55 bar, the control unit and turbine operate without issue. The nozzles in this case are piezoelectric and have high rail pressure. The engine is present in the 120d, 320d, 520d, and X1 vehicles. The most potent version is T0 or TOP, which was manufactured during the standard years 2007–2013. A contemporary exhaust, piezo injectors, and two turbocharged compressors with a 2 bar blowing capacity emerged here. The ECU is also new, and the pressure in the rail has increased much more. It produces 204 horsepower at 4400 rpm and 400 N* m of torque between 2000 and 2250 rpm. It costs X1 or 123d. Production of K1 or TU lasted from 2011 to 2015. He acquired the newest turbine and took the place of his predecessors. This motor is more energy-efficient than previously, and consumption has dropped by 3%. Here, the engine produces 116 horsepower at 4000 rpm and 260 N* m of torque at 2500 rpm. Engine settings are 116d, 316d, and X1. There are also U1, O1, T1, and U1; they hardly vary from their forerunners.
