BMW 116d (E87) engine: which one, problems and replacement

The BMW 116d in the first 1 Series five-door generation (E87, built 2004–2011) was built with 2 different engines over its life: the N47D20A (116 hp, 2007–2015) and the N47D16 (116 hp, 2010–2015).

Below you will find how to identify the engine in your 116d, the faults to look for, current prices for a replacement and the swap options that make sense.

• Generation: first 1 Series five-door, 2004–2011
• Body styles: E87 (hatchback)
• Engines: N47D20A, N47D16
• Output: 116 hp
• Replacement engines in stock: 343 from 737,00 €

Which engine is in your 116d?

N47D20A in the 116d

The N47D20A was used in the E87 116d, built 2007–2015. It is a 2.0 L turbocharged diesel inline-4 with 116 hp and 260 Nm. It has the same output as the N47D16, so the build date decides which one your car has.

Reading the code: N marks an N-series code, the generation of BMW engines introduced from 2001; 47 is the family number; D stands for diesel; 20 is the capacity in decilitres, so 2.0 litres; A identifies the version or output stage.

N47D16 in the 116d

The N47D16 was used in the E87 116d, built 2010–2015. It is a 1.6 L turbocharged diesel inline-4 with 116 hp and 260 Nm. It has the same output as the N47D20A, so the build date decides which one your car has.

Reading the code: N marks an N-series code, the generation of BMW engines introduced from 2001; 47 is the family number; D stands for diesel; 16 is the capacity in decilitres, so 1.6 litres.

116d engines by model year

The engine changed once during the E87 run, in 2010. 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 116d

A replacement engine does not have to come from another 116d. 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.

N47D20A: BMW E90 316d, BMW F30 316d.

N47D16: BMW F20 114d, BMW F20 116d.

How to confirm your engine code

Because the 116d 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 116d engine problems

The N47D20A and N47D16 in the 116d 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.

Symptoms to watch for on the 116d

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 116d engine

• 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.

Buying a used engine for the 116d: checklist

1. Why your old engine failed. Before fitting a replacement, find out why the original failed. An overheating radiator, a blocked intercooler or a failed turbo can destroy a second engine if they are not fixed.
2. Sump, oil pickup and drive variants. Rear-drive, xDrive and front-drive cars can use different sumps, oil pickups and engine mounts even with the same engine code. Check that the sump matches your subframe and front axle.
3. Photographs from every side. Good suppliers photograph the actual engine you will receive. Look for the block stamp, the sump, the timing cover and any broken brackets or connectors in the pictures.
4. 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.
5. 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.
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 116d replacement engine cost

Our 116d engine stock runs to 343 units, priced from 737,00 € to 4.314,00 € with a median of 1.657,00 €.

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.

116d engine prices by model year

Engines from 2000–2004 have a median of 4.090,00 €, while units from 2020–2024 sit at 2.752,00 €. Newer engines usually cost more because they come from younger donor cars with lower mileage and later updates.

116d 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.

5 of these come from E87 donor cars, priced from 857,00 € to 2.614,00 €. 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 116d

These engines were fitted to other versions of the E87 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 N43B16 in my 116d?

It is a full conversion: the N43B16 runs on petrol and the N47D16 on diesel, so the fuel system, wiring, engine control unit, instrument coding and usually the gearbox change too. The gain is 6 hp and 0 Nm. In Germany and most of Europe an engine swap must be inspected and registered.

Can I fit the N46B20 in my 116d?

It is a full conversion: the N46B20 runs on petrol and the N47D16 on diesel, so the fuel system, wiring, engine control unit, instrument coding and usually the gearbox change too. The gain is 34 hp and 0 Nm. In Germany and most of Europe an engine swap must be inspected and registered.

Can I fit the M47TUD20 in my 116d?

Yes, it is one of the more common upgrades. Both are diesel inline-4 engines, so the mounting points are similar, but the M47TUD20 needs its own wiring and engine control unit, the matching gearbox or clutch, and often a different sump, cooling and exhaust. The gain is 34 hp and 70 Nm. In Germany and most of Europe an engine swap must be inspected and registered.

Fitting a replacement engine in the 116d

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.
