BMW M47 engine: the complete buyer's guide

The M47 is BMW's 2.0 litre four-cylinder diesel from 1998 to 2007. It powered the E46 318d and 320d, the E39 520d, the E60 520d, the E83 X3 2.0d, the E87 118d and 120d, and early E90 318d and 320d models.

It is a durable engine with simple maintenance. Swirl flaps and the EGR system are the main concerns. A used M47 with good compression and a clean intake is a reliable choice.

History of the M47

BMW launched the M47 in 1998 with a distributor injection pump. The M47TU of 2001 moved to common-rail injection, and the M47TU2 of 2004 increased power to 163 hp. The N47 replaced it from 2007.

1998: the M47D20 arrived with 2.0 L and 136 hp in the BMW E46 320d and BMW E39 520d.

2001: the M47TUD20 arrived with 2.0 L and 150 hp in the BMW E46 320d, BMW E83 X3 2.0d and BMW E87 120d. Compared with the M47D20, it added 14 hp.

Every M47 version explained

M47D20 (2.0 L, 136 hp)

Built from 1998 to 2007, the M47D20 displaces 2.0 L in an inline-4 layout and is turbocharged. It produces 136 hp and 280 Nm on diesel. That is about 68 hp and 140 Nm per litre, a relaxed tune aimed at torque, durability and economy. Within the M47 family, the M47TUD20 (150 hp) is more powerful. It was fitted to the BMW E46 320d and BMW E39 520d.

Reading the code: M marks an M-series code, the naming BMW used for its engine families up to the early 2000s; 47 is the family number; D stands for diesel; 20 is the capacity in decilitres, so 2.0 litres.

We have 199 M47D20 units in stock, priced from 1.073,00 € to 1.846,00 €.

M47TUD20 (2.0 L, 150 hp)

Built from 2001 to 2007, the M47TUD20 displaces 2.0 L in an inline-4 layout and is turbocharged. It produces 150 hp and 330 Nm on diesel. That is about 75 hp and 165 Nm per litre, a strong figure for a road engine of its era. Within the M47 family, it is the most powerful version, while the M47D20 (136 hp) is milder. It was fitted to the BMW E46 320d, BMW E83 X3 2.0d and BMW E87 120d.

Common M47 problems and what to check

No engine is perfect. These are the faults our workshop sees most often on the M47, what causes them and how to check a used unit before you buy.

Swirl flaps

The swirl flaps in the intake manifold can loosen and break, and a broken flap can enter a cylinder and destroy the engine.

How to check: Check whether the flaps have been removed or replaced with blanks.

EGR valve and cooler

The EGR valve clogs with soot and the cooler can leak.

How to check: Check for EGR fault codes and coolant loss.

Injectors

Common-rail injectors leak or fail.

How to check: Read injector correction values.

Turbocharger

Turbos wear and leak oil.

How to check: Check shaft play.

Glow plugs

Glow plugs fail and cause hard cold starts.

How to check: Check the glow plug system.

Diagnosing a failing M47: symptoms and causes

If your current engine is showing one of these symptoms, this table helps you judge whether it can be repaired or whether a replacement M47 is the better route.

Knocking from the bottom of the engine. A deep knock that rises with engine speed usually means worn rod or main bearings. Stop driving: bearing failure ends with a broken connecting rod. A used engine is normally the most economical fix once the bottom end is damaged.

Overheating or losing coolant. Coolant loss without visible leaks points to a head gasket or a cracked head; visible leaks point to the water pump, hoses, thermostat housing or expansion tank. Overheating should be fixed before it warps the head.

White smoke that smells sweet. Coolant burning in the cylinders, from a head gasket, a cracked head or, on diesels, a leaking EGR cooler. Check the coolant level and look for oil in the coolant.

Blue smoke. Oil burning in the cylinders. A puff on start-up points to valve stem seals; constant smoke under load points to piston rings or, on turbo engines, turbo seals.

Rough idle or misfire. Ignition coils, spark plugs, injectors and vacuum leaks are the usual causes. A misfire on one cylinder that moves when you swap coils is a coil; one that stays is a plug, injector or compression problem.

Loss of power. Start with the simple things: air filter, boost leaks on turbo engines, fuel pressure and fault codes. A gradual loss with poor compression on a test points to internal wear.

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.

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.

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.

Repair or replace your M47?

Repair makes sense when the fault is outside the engine or in a part that can be replaced without opening it: sensors, coils, injectors, gaskets, the water pump or a turbo. Replacement makes sense when the bottom end, the crankshaft, the bores or the head are damaged, because rebuilding an M47 properly costs more than a good used unit.

Ask your workshop for a written diagnosis before deciding. A compression test, an oil analysis and a borescope inspection take an hour or two and remove most of the guesswork.

M47 maintenance and running costs

Fit swirl flap blanks and clean the intake when installing a used M47.

The single best thing you can do for an M47 is to change the oil more often than the longest factory interval. Clean oil protects bearings, chains, VANOS units and turbochargers, and costs far less than any of them.

Let a turbocharged engine idle for thirty seconds after hard driving so the turbo can cool, and warm it up gently before using full boost.

Diesels need regular longer runs to regenerate their particulate filter. If the car mostly does short trips, plan a motorway drive every few weeks.

Buying a used M47: the full checklist

Work through these points before you order a used M47, whoever you buy from.

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. 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.
10. 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.
11. 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.
12. 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.
13. 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.
14. 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.

M47 prices: what you should pay

Across 199 M47 units in our stock today, prices start at 1.073,00 € and reach 1.846,00 €. The median — the price in the middle of the range — is 1.455,00 €.

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.

M47 prices by model year

Engines from 2000–2004 have a median of 1.464,00 €, while units from 2005–2009 sit at 1.455,00 €. Newer engines usually cost more because they come from younger donor cars with lower mileage and later updates.

M47 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.

Fitting a replacement M47

These are the steps we recommend to every workshop fitting one of our M47 engines.

1. Compare the engines side by side. Put the replacement next to the old engine and compare sensors, brackets, connectors, the sump, the starter and the flywheel or flexplate. Note anything that must be transferred.
2. Transfer the parts that differ. Move the parts that are specific to your car, such as the engine harness on some models, the sump on xDrive cars or the air conditioning compressor bracket. Use new seals and gaskets for everything you move.
3. Replace the rear main seal and drive parts. With the engine out, the rear crankshaft seal is easy to reach. Fit a new one, inspect the flywheel and clutch on manual cars or the converter seal on automatics.
4. Renew the cooling system. Most engine failures start with cooling. Fit a new water pump, thermostat and hoses, check the radiator and fan, and use the correct coolant.
5. Fit new engine mounts. Old mounts transfer vibration and can let the engine move enough to damage hoses. They are cheap and easy to replace with the engine out.
6. 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.
7. 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.
8. 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.
9. Clean the intake. If the old engine failed internally, debris can be in the intake or intercooler. Clean them so nothing reaches the new engine.
10. 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.
11. 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.
12. 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.
13. 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.

Tuning and upgrades

Remaps add around 30 hp.

Whatever you plan, start with a healthy engine: a compression test, fresh fluids and the known weak parts replaced. Power upgrades amplify any existing problem.

M47 compared with similar BMW engines

Buyers often compare the M47 with these engines. Here is how they line up.

The B47 reaches higher outputs (up to 190 hp against 150 hp) and uses timing chain at the rear (gearbox end). Its best-known faults are egr cooler and diesel particulate filter. Read the B47 guide.

The M21 and M41 is milder (up to 115 hp against 150 hp) and uses timing belt on the m21, chain on the m41. Its best-known faults are injection pump and head cracks. Read the M21 and M41 guide.

The N47 reaches higher outputs (up to 218 hp against 150 hp) and uses timing chain at the rear (gearbox end). Its best-known faults are timing chain and swirl flaps. Read the N47 guide.

Delivery, warranty and payment

Before an M47 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.

Questions buyers ask about the M47

What is the BMW M47D20TU2 engine?

The BMW M47D20TU2 is a 2.0 liter (1,995 cc) diesel engine from the M47 family. It has an inline 4, DOHC, 16 valve layout with a variable-geometry turbocharger, and makes 120 kW (163 HP) with 340 Nm of torque. BMW built it from 2001 to 2007 and it meets the Euro 4 emission standard.

You find the M47D20TU2 in the BMW E46 320d, BMW E46 320td, BMW E39 520d, BMW E60 520d and BMW E87 120d. What we list: BMW M47 2.0 turbo diesel engines for E46, E39 and early E60.

At Autowerke Engines every M47D20TU2 is a real used engine from our yard in Hamburg. Each engine in the yard is inspected in Hamburg. The code is matched to the listing, the parts on the engine are recorded, the openings are sealed and the real unit is photographed. Each listing shows the year, the mileage and the price, so you can compare units side by side.

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.

How much does a used BMW M47D20TU2 engine cost?

A used BMW M47D20TU2 engine in our yard usually costs between 1.050 € and 1.850 €. 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.

Which cars use the BMW M47D20TU2 engine?

BMW fitted the M47D20TU2 to the BMW E46 320d, BMW E46 320td, BMW E39 520d, BMW E60 520d and BMW E87 120d. These cars were built with this engine from about 2001 to 2007.

The badge on the boot is not enough to be sure. The same model name can hide two different engines, for example after a facelift or a change in emission rules. Always read the engine code stamped on the block, or look it up with your VIN.

The M47D20TU2 is the only M47 version we list, which makes it easy to pick, but the wiring and the engine computer still need to match your car.

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.

How much power and torque does the BMW M47D20TU2 have?

From the factory the BMW M47D20TU2 makes 120 kW (163 HP) and 340 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 M47D20TU2 on our site lists its year and mileage. If you want more photos or a short video of a unit, ask the desk and we send them before you pay.

How do I know a used M47D20TU2 engine is in good shape?

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. An inspection certificate for the unit can travel with the order when you ask for it.

When you look at a listing, check the recorded mileage, the year and the photos of the ports and the stamp. Ask for photos of anything you want to see closer. You can ask for extra photos, a close-up of the code stamp or a short video before you order.

On a diesel like the M47D20TU2, a careful fitter will also look at the injectors, the turbo shaft play and the oil in the intake before the engine goes in.

If the engine fails inside under normal use, the warranty covers you. 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.

What comes with a used M47D20TU2 engine?

Each M47D20TU2 is sold as described on its own listing. The yard writes down the parts that are fitted to that unit, such as the turbo, the injectors, the manifolds or the alternator, so you know what arrives.

Some units are long engines with few ancillaries, others are more complete. If you need a part that is not listed, ask the desk. We often have the matching items in the yard.

Every engine is drained, sealed at each opening, strapped to a heat-treated pallet and shrink-wrapped, then photographed before it leaves the yard.

On delivery, the carrier brings the pallet to the kerb or a loading bay. Please have a forklift, a pallet truck or an engine crane ready.

Is the BMW M47D20TU2 a diesel or petrol engine?

The M47D20TU2 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 4 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.

Are there other versions of the BMW M47D20TU2?

In our yard the M47D20TU2 is the only listed version of the M47 family. It makes 120 kW (163 HP) and 340 Nm, and was built from 2001 to 2007.

Engines in one family share a basic block, but the turbo, the injection, the sensors and the engine computer can differ. A higher power version often has different pistons, a bigger turbo or a different fuel system.

This is why we ask for the exact code. Fitting a different version can work, but the wiring, the software and sometimes the gearbox must be changed to match.

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.

How long does delivery of an M47D20TU2 engine take?

Orders confirmed before 14:00 CET on a working day leave Hamburg the same day. Later and weekend orders leave the next working day. Delivery to the Netherlands, Belgium, Germany, France, Luxembourg and Denmark takes 1 to 3 working days.

Spain, Italy, Portugal, Poland, Czechia, Austria, Ireland, the Nordics and the Baltics take 2 to 5 working days. Greek and Spanish islands, Malta, Cyprus and remote areas take 4 to 8 working days. The UK and other countries outside the EU are quoted one by one.

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. Every engine is drained, sealed at each opening, strapped to a heat-treated pallet and shrink-wrapped, then photographed before it leaves the yard.

You get a tracking number when the pallet is collected. Check the wrapping before you sign, and note any damage on the paperwork.

What should I replace when I fit a used M47D20TU2 engine?

A used engine lasts longest when it starts life in your car with fresh fluids and new seals. 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. Change the drive belt, the thermostat and the water pump seals if they look tired, because they are cheap while the engine is out. 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.

Does a used M47D20TU2 engine come with a warranty?

Yes. 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.

The warranty does not cover damage from wrong fitting, overheating, low oil, wrong fluids or fuel, engines that were opened or modified without our approval, or labour and towing costs.

To claim, send us your order number, a short description of the problem, photos or a video, and a mechanic's report if we ask for one. If the claim is approved, we repair, replace or refund the engine.

Keep the receipts for the fitting, the oil and the filters. They make any claim quick and simple.

Can you check if an M47D20TU2 fits my car with my VIN?

Yes, and it is free. Send the 17-character VIN of your car and, if you have it, the gearbox code. We check the engine family, the build year window and the parts your car needs.

For the M47D20TU2, we confirm that your car was built with this code or with a version that can take it. BMW used it in the BMW E46 320d, BMW E46 320td, BMW E39 520d, BMW E60 520d and BMW E87 120d.

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.

What should I know about the BMW M47 engine?

BMW M47 2.0 turbo diesel engines for E46, E39 and early E60. We list one version: M47D20TU2 (2.0 liter (1,995 cc), 120 kW (163 HP), 2001 to 2007).

Because there is only one version, the code is easy to match. You still need the engine computer and wiring that suit your car.

The M47 family was used in chassis E46, E39, E60 and E87. Before a unit is listed, the yard checks the engine code against the listing, writes down the parts fitted to it, seals every opening and photographs the real engine you will receive.

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.

What should I check on a used BMW M47 engine?

Start with the basics: the engine code on the block, the recorded mileage and the photos. Make sure the code matches your car and the parts you need are on the unit.

On an M47 diesel, a fitter usually checks the turbo for shaft play, the intake for heavy oil or soot, the injector seals and the glow plugs. These parts are easy to check before fitting and easy to change if needed.

You can ask for extra photos, a close-up of the code stamp or a short video before you order. An inspection certificate can travel with the order on request.

Once fitted, change the oil and filter early and drive gently at first. Report any problem right away so the warranty stays valid.

Which years were BMW M47 engines made?

BMW built the M47 engines we list from about 2001 to 2007. The M47D20TU2 ran from 2001 to 2007.

They went into chassis E46, E39, E60 and E87. The exact year of a car matters, because BMW sometimes changed the engine version or its parts in the middle of a model's life.

Each listing in our yard names the engine year, so you can match it to the build date of your car.

Can I put an M47D20 engine in my Defender 110?

Yes. We sell conversion kits that fit the M47D20 into the Defender 110. The kit replaces the 200Tdi and Td5, and works with the R380 and LT77.

You can buy the full package with an engine, or only the parts you need: complete conversion with engine, complete conversion, adapter plate, engine mount, wiring and ecu and cooling and exhaust.

A swap like this needs a skilled workshop. Mounts, the adapter, the wiring and the engine computer, the cooling and the exhaust all have to work together. Check your local road rules for engine swaps before you start.

How hard is an M47 Defender swap?

A M47D20 swap into the Defender 90 and Defender 110 is a big job, but a good workshop can do it with a complete kit. Most of the time goes into the mounts, the adapter and the wiring.

The usual steps are: remove the old engine, fit the new mounts and the adapter plate, set the engine in, connect the wiring and the engine computer, then fit the cooling and the exhaust. A test drive and a final check follow.

Our kits come with parts that are made to work together, which saves time and guesswork. What we list: Lighter BMW M47 2.0 diesel kits for Defender 90 and 110.

Before you start, check your local rules for registration and road tests after an engine change. We supply invoices and documents that help with this.

Glossary

• Wastegate — A valve that lets exhaust gas bypass the turbine to control boost pressure. Worn wastegates rattle and can cause boost faults.
• EGR — Exhaust gas recirculation. It feeds some exhaust back into the intake to reduce NOx emissions but builds up soot.
• Swirl flaps — Flaps in the intake manifold that create swirl at low revs. On some BMW diesels they can break and enter the engine.
• Common rail — A diesel injection system with a high-pressure fuel rail feeding all injectors. It allows precise, multiple injections per cycle.
• Long block — An engine with the block, head and internals but without most ancillaries such as manifolds, turbo, alternator or starter.
• Dressed engine — An engine with most ancillaries fitted, ready to install with fewer parts transferred.
• Compression test — A measurement of the pressure each cylinder builds when cranked. Even readings show healthy rings and valves.
• Leak-down test — A test that pressurises each cylinder and measures how much air escapes, showing where any leak is.
• LCI — Life Cycle Impulse, BMW's name for a mid-life update. Engines often change at the LCI.
• xDrive — BMW's all-wheel-drive system. xDrive cars often use a different sump and oil pickup.
• DME — Digital Motor Electronics, BMW's name for the engine control unit.
• CAS, FEM and BDC — The immobiliser and body modules that must be matched to the engine control unit on modern BMWs.
• Timing chain tensioner — A hydraulic or spring device that keeps the timing chain tight. Worn tensioners cause cold-start rattle.
• TU — Technical Update, BMW's suffix for a revised version of an engine.

Our verdict

The M47 has a clear set of strengths and a known list of weak points. Check the code against your VIN, ask for compression figures and photographs, replace the known weak parts while the engine is out, and fit it with fresh fluids and filters. Do that and a used M47 will give years of service.
