Some of the modern BMW models that use diesel fuel include the 3 Series, including the 320d and 330d, the 5 Series such as the 520d, 530d, and 540d, and the 7 Series is available with a diesel engine option, which is the 740d.

Also, the BMW X1 is a compact crossover SUV that is available with a diesel engine option, and their X3 is a mid-size crossover SUV that is available with diesel engine options, such as the xDrive20d and xDrive30d. The X5 and the X7 full-size SUVs are also available with a diesel engine option.

The availability of diesel engine options may vary depending on the market and the specific model year of the BMW vehicle. Regardless of your model, maintaining your BMW diesel engine in top condition requires a combination of proper care & regular maintenance . Here are some tips to help you keep your BMW diesel engine running smoothly for years to come.

Use High-Quality Diesel Fuel

Keep the Engine Cool

Diesel engines generate a lot of heat, so it’s important to keep the engine cool. Make sure the cooling system is functioning properly and keep an eye on the temperature gauge while driving.

Here are some ways to keep a BMW diesel engine cool:

Regularly inspect the cooling system components such as the radiator , hoses , and coolant level , and make sure they are in good condition. If there are any signs of damage or leaks, have them repaired or replaced as soon as possible.

The fan and fan clutch play a crucial role in keeping the engine cool. Check the fan blades for any damage or cracks, and ensure the fan clutch is functioning correctly.

This may include turning off the air conditioning and opening the windows, or pulling over to let the engine cool down.
