B47D20B compared with other B47 versions

B47D20B or B47C20?

The B47C20 has the same 190 hp as the B47D20B, from the same 2.0 L, and was built 2014–2026. Versions of the same size share the block and most mounting points, but the turbo or intake, injectors, software and sometimes the sump differ. Fitting one in place of the other usually means transferring parts and coding the engine control unit, so the simplest choice is the code your car left the factory with.

Buying a used B47D20B: checklist

1. Gearbox and flywheel match. Manual and automatic engines differ at the flywheel or flexplate, and sometimes at the crankshaft spigot. Make sure the engine you buy matches your gearbox or that you transfer the right parts.
2. Compression or leak-down figures. Even compression across all cylinders tells you more than mileage. Ask for the figures, not just a pass or fail, and compare the highest and lowest readings: a spread above 10 to 15 percent deserves a question.
3. Confirm the exact engine code. Read the code stamped on the block and compare it with the code for your car. Send us the last seven characters of the VIN and we confirm the match before anything is paid.
4. Warranty terms in writing. Read what the warranty covers, how long it runs and what fitting conditions apply. Most warranties require a qualified workshop, new fluids and filters, and replacement of the cooling parts that caused the original failure.
5. List of what is fitted. Engines are sold with different ancillaries: some have the turbo, injectors, manifolds, alternator and starter, others are long blocks. Agree the list in writing so you know which parts must come from your old engine.
6. Turbocharger shaft play and oil. Rotate the compressor wheel by hand. A small amount of side play is normal; in-and-out play or wheel contact with the housing is not. Oil pooled in the intake or intercooler pipes points to worn seals.
7. Injector correction values. On a diesel that can be run before removal, the injector correction values show whether one injector is delivering more or less fuel than the others. Large deviations mean an injector is on its way out.
8. Particulate filter and EGR history. Short-trip diesels clog their DPF and EGR systems. The engine may be fine, but ask whether the donor car had DPF warnings, and plan to clean or check your own filter before fitting.
9. Timing chain noise. Listen for a rattle at the front of the engine for the first seconds after a cold start. On an engine that cannot be run, look at the chain guides through the oil filler or with the valve cover off.
10. Gearbox-end timing chain. On this engine the timing chain sits at the gearbox end, so replacing it normally means removing the engine. If the chain has not been replaced, the time to do it is before the engine goes into your car.

What comes with a used B47D20T engine?

What should I replace when I fit a used B47D20T engine?

A used engine lasts longest when it starts life in your car with fresh fluids and new seals. Clean the intercooler and the intake pipes, and fill the turbo oil feed with clean oil before the first start, so the turbo never runs dry. Fit a new oil filter and fresh oil of the grade BMW lists for this engine, and refill the coolant with the correct BMW antifreeze mix. Use new gaskets for the exhaust manifold, the intake and the sump plug, and check every hose clip before the first start.

Look at the engine mounts and the clutch or the torque converter while the engine is out. Old mounts can crack a new engine's brackets, and a worn clutch is much easier to change now.

Before the first start, turn the engine over without fuel until the oil pressure light goes out. Then let it idle, check for leaks, and drive gently for the first few hundred kilometres.

The warranty asks for fitting by a qualified mechanic and the correct oil, coolant and filters. Keep your receipts in case you ever need to make a claim.

What is the difference between the BMW B47 engines?

BMW B47 2.0 modular diesel engines for F30, G20, G30 and X3. We list 2 versions: B47D20 (2.0 liter (1,995 cc), 140 kW (190 HP), 2014 to 2023); B47D20T (2.0 liter (1,995 cc), 170 kW (231 HP), 2015 to 2022).

The versions share the same basic design, but the power, the turbo or injection set-up, the electronics and the emission standard change. The right one for you is the one your car was built with.

The B47 family was used in chassis F30, G20, G21, G30, F48, G01 and F32. The photos on each listing show the actual engine, not a stock picture. The yard checks the code, records what is bolted on, and seals the openings before the engine is offered.

Is the BMW B47D20T a diesel or petrol engine?

The B47D20T is a diesel engine. It is a 2.0 liter (1,995 cc) inline 4, DOHC, 16 valve unit with twin turbochargers, and it was built to the Euro 6 emission standard.

The emission standard matters for registration and for low-emission zones in many cities. When you replace an engine with the same code, the car keeps the same paperwork and the same emission class.

Diesel versions need the matching exhaust treatment parts on the car to stay legal and to keep the engine computer happy. Reuse the parts from your car if they are in good condition.
