Purpose and compatibility

The offered B47D20A engine is dedicated to BMW vehicles with all-wheel drive, specifically in the 120dX, 320dX, and 420dX versions. The unit's design was developed with dynamic driving in mind, while maintaining reasonable fuel consumption and appropriate component durability.

The engine falls under the Engines category, meaning it is a complete power unit intended for installation in the engine bay, rather than a single accessory component. As a result, it can be used both for major post-accident repairs and for replacing a worn-out unit in vehicles subjected to intensive use.

Construction and technical characteristics

The B47D20A engine is a modern, four-cylinder diesel with a compact, modular design. The cylinder layout has been optimized to reduce vibration and noise, which translates into more comfortable operation under typical road conditions. The use of a high-pressure injection system and advanced engine management allows for precise fuel dosing and efficient power utilization.

This unit features a new timing chain kit, which significantly reduces the risk of typical failures associated with timing component wear in diesel engines. For the user, this means a greater margin of operational safety and a reduction in potential repair costs in the near future.

Condition, mileage, and practical application

The engine comes from the secondary market and is offered as a used component, which allows for optimized repair costs compared to a brand-new unit. The declared mileage is relatively low for a modern diesel, which, combined with the replaced timing, makes this unit an attractive option for specialized workshops and informed users.

The B47D20A unit is well-suited for the following applications:

• comprehensive replacement of a damaged engine in BMW 1, 3, or 4 Series with xDrive,
• repair of post-accident vehicles where the front section of the body and the factory engine were damaged,
• restoration projects where maintaining the original BMW powertrain specification is a priority.

Benefits of choosing the B47D20A unit

By choosing this power unit, you gain:

• Original BMW construction – full compatibility with the factory vehicle architecture, without the need for modifications to the wiring or mounts.
• New timing chain kit – a key element affecting engine reliability has already been replaced, reducing the risk of failure in this area.
• Modern four-cylinder diesel – a balance between performance and fuel economy, suitable for both fleet and private vehicles.
• Possibility of professional refurbishment or further adaptation – the unit serves as a good base for further service work if the workshop plans additional preparatory steps.
