320d engines by model year

The engine changed 3 times during the F30 run, in 2014, 2016 and 2017. Changes usually come with BMW's mid-life update (LCI) or a new emissions standard, so a car registered early in a year can still have the older engine. The VIN settles it.

Other cars with the same engine as the 320d

A replacement engine does not have to come from another 320d. These models left the factory with the same engine code, so a unit from any of them is a candidate donor once the sump, mounts and ancillaries are matched to your car.

N47D20: BMW E90 320d, BMW F20 120d, BMW E84 X1 20d, BMW F25 X3 20d, BMW E60 520d.

N47D20D: BMW E90 320d, BMW F20 120d.

B47D20: BMW G20 320d, BMW G30 520d, BMW G01 X3 20d, BMW G05 X5 25d.

B47D20B: BMW G20 320d, BMW G01 X3 20d.

How to confirm your engine code

Because the 320d used more than one engine, the badge alone does not tell you which one your car has. The build date is the first clue; the VIN is the proof. Send us the last seven characters of the VIN and we read the engine code from BMW's records, or look for the code stamped on the block. How to find your BMW engine code.

Known 320d engine problems

N47D20 and N47D20D (N47 family)

The N47D20 and N47D20D in the 320d share the known weak points of the N47 family. Full N47 guide.

Timing chain. The timing chain stretches and in the worst case breaks, causing major engine damage. Engines built before 2011 are most affected.

Swirl flaps. Swirl flaps can stick or break.

EGR cooler. The EGR cooler can leak coolant; BMW issued a recall for some cars.

Diesel particulate filter. The DPF clogs on short-trip cars.

Injectors. Injectors leak or fail.

B47D20 and B47D20B (B47 family)

The B47D20 and B47D20B in the 320d share the known weak points of the B47 family. Full B47 guide.

EGR cooler. BMW recalled many B47 cars to replace the EGR cooler, which could leak and cause a fire risk.

Diesel particulate filter. The DPF clogs on short-trip cars.

Injectors. Injectors leak or fail.

Symptoms to watch for on the 320d

Rattle for a few seconds after a cold start. The classic sign of a weak timing chain tensioner or stretched chain. It must be checked quickly: a chain that jumps a tooth can bend valves.

Rattle or whine from the gearbox end. On engines with the timing chain at the rear, a rattle or whine from the back of the engine is the warning sign of chain stretch or guide wear.

Whistle, loss of boost or limp mode. A split charge pipe, a sticking wastegate or worn turbo bearings. Check the pipes first, then the turbo shaft for play.

Black smoke under acceleration. Too much fuel for the air available: boost leaks, a sticking EGR valve, a dirty air mass meter or a leaking injector.

Hard starting when cold. Glow plugs or the glow plug control unit. On older diesels, also check the injection pump and fuel lines for air leaks.

Particulate filter warning. Short trips stop the DPF from regenerating. A long motorway run often clears it; a filter that keeps blocking may be covering an injector, EGR or turbo problem.

Sudden metallic noise followed by misfire. On diesels with swirl flaps, a broken flap or screw can enter a cylinder. Stop the engine immediately; continued running usually destroys the piston and head.

Looking after the 320d engine

N47 engines

• Oil: 5W-30 BMW Longlife-04, about 5.25 litres.
• Service interval: Oil every 10,000 to 15,000 km.
• Timing drive: Timing chain at the rear (gearbox end).
• Workshop notes: Replace the timing chain and guides when fitting a used N47 unless they were recently done.

B47 engines

• Oil: 0W-30 or 5W-30 BMW Longlife-04, about 5.25 litres.
• Service interval: Oil every 15,000 km or yearly.
• Timing drive: Timing chain at the rear (gearbox end).
• Workshop notes: Check front-drive (B47C) or rear-drive (B47D) before ordering.

Buying a used engine for the 320d: checklist

1. Ask how the donor car was damaged. Most good used engines come from cars with body damage. A front-end impact can crack sensors, the timing cover or the sump; a rear or side impact usually leaves the engine untouched. The yard records the damage on each unit.
2. 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.
3. Look at the oil and coolant. Clean oil without metal particles and coolant without oil are good signs. Milky oil, oily coolant or a burnt smell mean the engine needs further checks before it is fitted.
4. 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.
5. 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.
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. Swirl flaps. Check whether the swirl flaps are in place, blanked or removed. Broken swirl flaps are a known cause of engine failure on several BMW diesels, so many owners fit blanking plates when the intake is off.
10. 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.
11. 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.

BMW 320d replacement engine cost

We currently hold 342 320d engine engines. The cheapest is 729,00 €, the most expensive 4.242,00 €, and half of them cost less than 2.797,00 €.

Prices depend on the exact version, the donor's mileage, how complete the engine is and the demand for that code. Higher-output versions, low mileage and dressed engines with turbo, injectors and ancillaries cost more; long blocks and higher mileage cost less.

320d engine prices by model year

Engines from 2000–2004 have a median of 3.473,00 €, while units from 2020–2024 sit at 1.639,00 €. Newer engines usually cost more because they come from younger donor cars with lower mileage and later updates.

320d engine prices by mileage

Mileage matters less than history on a well-maintained BMW engine, but it is a useful guide. A low-mileage unit from a younger car gives you more life for a modest premium.

61 of these come from F30 donor cars, priced from 936,00 € to 3.988,00 €. An engine from the same body is the most direct swap because the sump, mounts and ancillaries already match.

On top of the engine, budget for the workshop's labour and the parts that are best replaced while the engine is out: engine mounts, the rear main seal, cooling parts, a clutch or converter seal, fluids and filters.

Engine swaps and upgrades for the 320d

These engines were fitted to other versions of the F30 at the factory, which makes them the most practical upgrades: the body was designed around them and many parts are shared.

Can I fit the N47D20T1 in my 320d?

Yes, it is one of the more common upgrades. Both are diesel inline-4 engines, so the mounting points are similar, but the N47D20T1 needs its own wiring and engine control unit, the matching gearbox or clutch, and often a different sump, cooling and exhaust. The gain is 28 hp and 50 Nm. In Germany and most of Europe an engine swap must be inspected and registered.

Can I fit the N20B20 in my 320d?

It is a full conversion: the N20B20 runs on petrol and the B47D20B on diesel, so the fuel system, wiring, engine control unit, instrument coding and usually the gearbox change too. The gain is 55 hp and 0 Nm. In Germany and most of Europe an engine swap must be inspected and registered.

Can I fit the N26B20 in my 320d?

It is a full conversion: the N26B20 runs on petrol and the B47D20B on diesel, so the fuel system, wiring, engine control unit, instrument coding and usually the gearbox change too. The gain is 55 hp and 0 Nm. In Germany and most of Europe an engine swap must be inspected and registered.

Fitting a replacement engine in the 320d

1. Inspect or replace the timing chain parts. Look at the guides and tensioner. On high-mileage engines, replacing them now costs far less than doing it later.
2. Replace the rear timing chain if in doubt. On engines with the chain at the gearbox end, chain work needs the engine out. If the history is unknown, replace the chain, guides and tensioner before fitting.
3. Prepare the turbo. Fit new oil feed and return seals, clean the intercooler and pipes of any oil or debris from the old engine, and prime the turbo with oil before starting.
4. Code the injectors and bleed the fuel. Enter the injector correction codes into the ECU, check the glow plugs and bleed the fuel system so the engine does not crank dry.
5. Check the particulate filter. If the old engine failed with oil or coolant entering the exhaust, the DPF may be contaminated. Check its back-pressure before relying on it.
6. Fill with the right oil and prime it. Fill with new oil of the correct specification and a new filter. Crank with the fuel and ignition disabled until oil pressure builds.
7. Coding and adaptations. On modern BMWs, the engine ECU must be matched to the car's immobiliser (CAS, FEM or BDC). Reset adaptations, register the battery and clear faults with diagnostic software.
8. First start and leak check. Start the engine, let it idle and watch oil pressure, temperature and fault codes. Check for leaks and bleed the cooling system.
9. First 1,000 km. Drive gently for the first few hundred kilometres, vary the engine speed and avoid full load. Change the oil and filter after about 1,000 km to remove any assembly debris.

How much power and torque does the BMW B47D20 have?

From the factory the BMW B47D20 makes 140 kW (190 HP) and 400 Nm of torque. It is a 2.0 liter (1,995 cc) inline 4, DOHC, 16 valve diesel engine with a variable-geometry turbocharger.

Because it is turbocharged, the torque comes in low in the rev range, which makes the car feel strong in everyday driving. A healthy turbo, a clean intercooler and tight boost pipes are key to getting the full figure.

A used engine reaches its factory numbers when it is fitted with the matching engine computer and software, and serviced with the right oil and filters. If the engine computer from your car is a different version, a specialist may need to code it.

Every B47D20 on our site lists its year and mileage. Ask the desk for more pictures of any listing. We are happy to show the stamp, the ports and the ancillaries before you decide.

For the B47D20, we confirm that your car was built with this code or with a version that can take it. BMW used it in the BMW F30 320d, BMW G20 320d, BMW G21 320d, BMW G30 520d and BMW F48 X1 xDrive20d and more.

We only reserve an engine once the match is confirmed, so you never pay for the wrong unit. You can reach the Hamburg desk by email at autowerkeengines@gmail.com, or by phone and WhatsApp on +49 15510 030835, Monday to Friday, 9:00 to 16:00 CET.

You can also use the VIN check on our site. It reads the year, the make, the model and the engine from the public vehicle register.

How much does a used BMW B47D20 engine cost?

A used BMW B47D20 engine in our yard usually costs between 2.150 € and 3.450 €. The exact price depends on the year, the mileage and the parts that come with the engine.

Our units show recorded mileage from about 22,000 km up to around 200,000 km. Lower mileage and more ancillaries mean a higher price. Each listing shows its own price, and the price you see is the price you pay. Prices include VAT for private buyers.

Shipping is a flat 249 € per order. It is added once at checkout and printed on the invoice, so there is no extra fee later. If you order a gearbox or a second engine on the same order, the fee is still charged once.

Inside the EU there is no import duty. For the UK and other non-EU countries, import duty and local VAT are paid by the receiver, and we supply a commercial invoice.

Is the BMW B47D20 a diesel or petrol engine?

The B47D20 is a diesel engine. It is a 2.0 liter (1,995 cc) inline 4, DOHC, 16 valve unit with a variable-geometry turbocharger, 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.

If you are not sure which version you need, send us your VIN. We tell you the right code for free.

How much is a replacement B47D20 engine for a BMW G21 320d?

A used B47D20 for the BMW G21 320d costs from about 2.150 € to 3.450 € in our yard. The price depends on the year, the mileage and the parts that come with the engine.

Shipping is a flat 249 € per order. It is added once at checkout and printed on the invoice, so there is no extra fee later. Inside the EU there is no import duty. Outside the EU, the receiver pays local duty and VAT.

A replacement engine is often much cheaper than rebuilding a damaged one, and much faster. The B47D20 you buy is photographed and checked in Hamburg before it is listed.

Eligible engines come with a 12 months warranty from the delivery date. It covers internal mechanical failure under normal use and correct fitting by a qualified mechanic or workshop. Not sure? Send us your VIN and your gearbox code. We match the engine family, the year window and the parts on the engine before anything is reserved, and the check is free.

Delivery, warranty and payment

Before a 320d engine leaves our Hamburg yard it is drained of oil and coolant, every opening is sealed, and it is strapped to a pallet and wrapped. We send photographs of the packed unit and the tracking details.

Door-to-door delivery is included to the address you give at checkout. Typical delivery takes three to five working days within Germany and neighbouring countries and five to ten working days to the rest of Europe and the UK.

A 12-month warranty covers eligible internal failure when the engine is fitted by a qualified workshop with new fluids and filters. You can pay by card, bank transfer or crypto and receive the invoice by email straight away.
