Which engine is in your 530i?

B48B20 in the 530i

The B48B20 was used in the G30 530i, built 2014–2026. It is a 2.0 L turbocharged petrol inline-4 with 258 hp and 400 Nm. It has the same output as the B48B20TU and B48B20B, so the build date decides which one your car has.

Reading the code: B marks a B-series code, BMW's modular engine family introduced from 2013 with 500 cc per cylinder; 48 is the family number; B stands for petrol, longitudinal installation for rear-drive and xDrive cars; 20 is the capacity in decilitres, so 2.0 litres.

B48B20TU in the 530i

The B48B20TU was used in the G30 530i, built 2018–2026. It is a 2.0 L turbocharged petrol inline-4 with 258 hp and 400 Nm. It has the same output as the B48B20 and B48B20B, so the build date decides which one your car has.

Reading the code: B marks a B-series code, BMW's modular engine family introduced from 2013 with 500 cc per cylinder; 48 is the family number; B stands for petrol, longitudinal installation for rear-drive and xDrive cars; 20 is the capacity in decilitres, so 2.0 litres; TU identifies the technical update.

B48B20B in the 530i

The B48B20B was used in the G30 530i, built 2019–2026. It is a 2.0 L turbocharged petrol inline-4 with 258 hp and 400 Nm. It has the same output as the B48B20 and B48B20TU, so the build date decides which one your car has.

530i engines by model year

The engine changed 2 times during the G30 run, in 2018 and 2019. 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 530i

A replacement engine does not have to come from another 530i. 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.

B48B20: BMW G20 330i, BMW F30 330i, BMW G01 X3 20i, BMW G05 X5 40i, Supra 2.0.

B48B20TU: BMW G20 330i, BMW G01 X3 30i, BMW G22 430i.

B48B20B: BMW G20 330i, BMW G01 X3 30i.

How to confirm your engine code

Because the 530i 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 530i engine problems

The B48B20, B48B20TU and B48B20B in the 530i share the known weak points of the B48 and B46 family. Full B48 and B46 guide.

Coolant leaks. Thermostat housings and coolant pipes leak.

Oil filter housing gasket. Leaks at higher mileage.

PCV and valve cover. Valve cover seals and PCV parts fail.

Water pump. The water pump can leak.

Symptoms to watch for on the 530i

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.

Looking after the 530i engine

• Oil: 0W-20 or 0W-30 BMW Longlife-17 FE+ or 01, 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 (B48A) or rear-drive (B48B) before ordering.

Buying a used engine for the 530i: checklist

1. 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.
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. 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.
4. 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.
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. 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.
8. 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.
9. 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.
10. 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.
11. 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.
12. 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.

BMW 530i replacement engine cost

Across 437 530i engine units in our stock today, prices start at 1.143,00 € and reach 4.795,00 €. The median — the price in the middle of the range — is 3.404,00 €.

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.

530i engine prices by model year

Engines from 2000–2004 have a median of 1.143,00 €, while units from 2020–2024 sit at 3.404,00 €. Newer engines usually cost more because they come from younger donor cars with lower mileage and later updates.

530i 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.

83 of these come from G30 donor cars, priced from 1.842,00 € to 4.185,00 €. 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.

Will it fit my 530i?

Will the B48B20TU fit my BMW G30 530i?

Yes, the BMW G30 530i left the factory with the B48B20TU, so a B48B20TU from another car is the direct replacement. The seventh 5 Series was built 2016–2023, 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 G30 530i?

We have 2 B48B20TU engines in stock, priced from 3.046,00 € to 4.795,00 €. Delivery to your door is included, and the engine carries a 12-month warranty when fitted by a qualified workshop. Add fitting labour and the parts you replace at the same time — seals, cooling parts and mounts — to estimate the total.

Will the B48B20B fit my BMW G30 530i?

The B48B20B is the original engine for the BMW G30 530i, which makes it the straightforward choice. The seventh 5 Series was built 2016–2023, and the B48B20B was produced 2019–2026, 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.

Add fitting labour and the parts you replace at the same time — seals, cooling parts and mounts — to estimate the total.

Engine swaps and upgrades for the 530i

These engines were fitted to other versions of the G30 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 B57D30 in my 530i?

It is a full conversion: the B57D30 runs on diesel and the B48B20B on petrol, so the fuel system, wiring, engine control unit, instrument coding and usually the gearbox change too. The gain is 7 hp and 220 Nm. In Germany and most of Europe an engine swap must be inspected and registered.

Can I fit the B57D30A in my 530i?

It is a full conversion: the B57D30A runs on diesel and the B48B20B on petrol, so the fuel system, wiring, engine control unit, instrument coding and usually the gearbox change too. The gain is 7 hp and 220 Nm. In Germany and most of Europe an engine swap must be inspected and registered.

Can I fit the B57D30T in my 530i?

It is a full conversion: the B57D30T runs on diesel and the B48B20B on petrol, so the fuel system, wiring, engine control unit, instrument coding and usually the gearbox change too. The gain is 62 hp and 280 Nm. In Germany and most of Europe an engine swap must be inspected and registered.

Fitting a replacement engine in the 530i

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

The full fitting and first-start procedure.
