B48A20 compared with other B48 versions

B48A20 or B48B20?

The B48B20 has 66 hp more than the B48A20 (258 against 192 hp), from the same 2.0 L, and was built 2014–2026. Versions of the same size share the block and most mounting points, but the turbo or intake, injectors, software and sometimes the sump differ. Fitting one in place of the other usually means transferring parts and coding the engine control unit, so the simplest choice is the code your car left the factory with.

B48A20 or B48B20TU?

The B48B20TU has 66 hp more than the B48A20 (258 against 192 hp), from the same 2.0 L, and was built 2018–2026. Versions of the same size share the block and most mounting points, but the turbo or intake, injectors, software and sometimes the sump differ. Fitting one in place of the other usually means transferring parts and coding the engine control unit, so the simplest choice is the code your car left the factory with.

B48A20 or B48B20B?

The B48B20B has 66 hp more than the B48A20 (258 against 192 hp), from the same 2.0 L, and was built 2019–2026. Versions of the same size share the block and most mounting points, but the turbo or intake, injectors, software and sometimes the sump differ. Fitting one in place of the other usually means transferring parts and coding the engine control unit, so the simplest choice is the code your car left the factory with.

Common B48A20 problems

The B48A20 shares its weak points with the rest of the B48 family. These are the faults to check on a used unit and on your own engine. The full explanation of each is in the B48 and B46 guide.

• Timing chain at the rear (gearbox end).

Will the B48A20 fit my car?

Will the B48A20 fit my MINI F56 Cooper S?

For the MINI F56 Cooper S, the B48A20 is the factory engine and the one to order. The third-generation MINI hatch was built 2014–2024, and the B48A20 was produced 2014–2024, so check that your car's build date falls inside that window. Confirm the drive type (front-drive or ALL4), 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 an MINI F56 Cooper S?

We have 3 B48A20 engines from F56 donor cars, priced from 1.448,00 € to 1.943,00 €. Delivery to your door is included, and the engine carries a 12-month warranty when fitted by a qualified workshop.

Yes, the BMW F48 X1 20i left the factory with the B48A20, so a B48A20 from another car is the direct replacement. The second X1 was built 2015–2022, and the B48A20 was produced 2014–2024, so check that your car's build date falls inside that window. Confirm the drive type (front-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 F48 X1 20i?

Buying a used B48A20: 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. 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.
3. 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.
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. 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.
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.

Questions about the B48A20

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.

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.

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.

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.

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.
