Will it fit? BMW G22, G23 and G26 4 Series engine questions

Will the B48B20TU fit my BMW G22 430i?

For the BMW G22 430i, the B48B20TU is the factory engine and the one to order. The second 4 Series coupé was built 2020–, and the B48B20TU was produced 2018–2026, so check that your car's build date falls inside that window. Confirm the drive type (rear-drive or xDrive), the gearbox (manual or automatic) and the emissions standard, because these can change the sump, the flywheel and the software. Send us the VIN and we check all of it for you.

How much is a replacement engine for a BMW G22 430i?

We do not have a B48B20TU on the shelf for the G22 430i at the moment. Units arrive regularly; send us your VIN and we will tell you when the next one is ready and what it will cost, including delivery.

Engine swap questions for the BMW G22, G23 and G26 4 Series

Owners often ask whether a more powerful engine from another BMW G22, G23 and G26 4 Series model can be fitted. These answers show what each upgrade involves.

Fitment and swap notes for the BMW G22, G23 and G26 4 Series

• The M440i uses the B58 with mild-hybrid assistance.
• Engine software must be coded to the car.

Engines from the same family usually share mounts and gearbox bolt patterns, but wiring, ECU, sump and cooling differ between versions. Moving to a different family is a conversion, not a replacement.

Known problems by engine in the BMW G22, G23 and G26 4 Series

B48 and B46

• Coolant leaks. Check for coolant loss.
• Oil filter housing gasket. Check the filter housing.
• PCV and valve cover. Look for oil on the head.
• Water pump. Check for coolant trails.

How to identify the right engine for your BMW G22, G23 and G26 4 Series

Start with the VIN. The last seven characters identify your car in BMW's systems, and from them we can confirm the engine code, the production date, the gearbox and whether the car has xDrive. That is the only reliable way to order.

Next, check the stamp on the block. On most BMW four- and six-cylinder engines it sits on the left side of the block below the intake; on V engines it is usually at the back near the gearbox. The stamp shows the engine code and serial number.

Finally, compare the ancillaries. Two engines with the same code can carry different turbos, injectors, manifolds or sensors depending on the model and market. Our listings show what is fitted to each unit.

Buying checklist for a BMW G22, G23 and G26 4 Series engine

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. 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.
13. 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.
14. VANOS operation. Rough idle, a rattle from the front of the head and a loss of torque at low revs point to VANOS seals or solenoids. These are serviceable parts and are easier to renew with the engine out.
15. Double VANOS units and solenoids. Ask for the adaptation values or fault history if the engine was running. Solenoids are inexpensive and are often replaced as a matter of course on a used engine.
16. Valvetronic motor and eccentric shaft sensor. The Valvetronic motor and its sensor cause limp-mode faults when they fail. Inspect the connector and the seal around the motor for oil.
17. Injectors and high-pressure fuel pump. Direct-injection engines rely on high-pressure pumps and precise injectors. Ask whether the injectors are original or updated and whether there were fuel pressure faults.

Fitting an engine to your BMW G22, G23 and G26 4 Series

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. 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.
8. 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.
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. Reset VANOS adaptations. Clear the VANOS adaptations so the ECU learns the camshaft positions of the new engine.
13. Teach the Valvetronic limit stops. Run the Valvetronic learning routine so the ECU knows the eccentric shaft limits.
14. 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.
15. 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.

Diagnosing engine trouble in a BMW G22, G23 and G26 4 Series

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

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.

Poor low-down torque and uneven idle. VANOS seals or solenoids. The engine may run well at high revs but feel flat and lumpy at low speed.

Limp mode with a Valvetronic fault. The Valvetronic motor, its eccentric shaft sensor or the wiring. The engine runs on a reduced throttle until it is repaired.

Long cranking before the engine starts. On direct-injection engines, a weak high-pressure fuel pump or leaking injector lets pressure drop when the engine is off.

Repair or replace the engine in your BMW G22, G23 and G26 4 Series?

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 engine properly costs more than a good used unit.

Timing chain work on the engine needs the engine removed. When the chain has failed and damaged valves or pistons, a replacement engine with a sound chain is often the same price as the repair.

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.

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.

Are there other versions of the BMW B48B20?

In our yard the B48B20 is the only listed version of the B48 family. It makes 190 kW (258 HP) and 400 Nm, and was built from 2015 to 2025.

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.

Is the BMW B48B20 a diesel or petrol engine?

The B48B20 is a petrol engine. It is a 2.0 liter (1,998 cc) inline 4, DOHC, 16 valve unit with a twin-scroll 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.

Petrol versions need the correct catalytic converters and oxygen sensors 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.

Can you check if a B48B20 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 B48B20, we confirm that your car was built with this code or with a version that can take it. BMW used it in the BMW G20 330i, BMW G21 330i, BMW G30 530i, BMW G01 X3 xDrive30i and BMW F30 330i 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 B48B20 engine cost?

A used BMW B48B20 engine in our yard usually costs between 2.650 € and 4.200 €. 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.

What should I replace when I fit a used B48B20 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.

Which years were BMW B48 engines made?

BMW built the B48 engines we list from about 2015 to 2025. The B48B20 ran from 2015 to 2025.

They went into chassis G20, G21, G30, G01, F30, F40 and G22. 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.

What should I check on a used BMW B48 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 a B48 petrol engine, a fitter usually checks the spark plugs, the coils, the timing side and the oil seals. 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.

How much power and torque does the BMW B48B20 have?

From the factory the BMW B48B20 makes 190 kW (258 HP) and 400 Nm of torque. It is a 2.0 liter (1,998 cc) inline 4, DOHC, 16 valve petrol engine with a twin-scroll 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 B48B20 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.

Glossary

• VANOS — BMW's variable camshaft timing system. It adjusts the intake camshaft (single VANOS) or both camshafts (double VANOS) to improve torque and emissions.
• Valvetronic — BMW's variable valve lift system. It controls engine load with the intake valves instead of a throttle plate, improving economy.
• Direct injection — Fuel is injected directly into the cylinder instead of the intake port. It improves efficiency but can cause carbon build-up on the intake valves.
• Wastegate — A valve that lets exhaust gas bypass the turbine to control boost pressure. Worn wastegates rattle and can cause boost faults.
• 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.
• Rear-mounted timing chain — A timing chain at the gearbox end of the engine. Replacing it normally requires removing the engine.
• TU — Technical Update, BMW's suffix for a revised version of an engine.
