N55B30T0 or N55B30?
The N55B30 has the same 306 hp as the N55B30T0, from the same 3.0 L, and was built 2009–2017. 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.
N55B30T0 or N55B30O0?
The N55B30O0 has 20 hp more than the N55B30T0 (326 against 306 hp), from the same 3.0 L, and was built 2013–2016. 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 N55B30T0 problems
The N55B30T0 shares its weak points with the rest of the N55 family. These are the faults to check on a used unit and on your own engine. The full explanation of each is in the N55 guide.
| Known fault | What to check |
|---|---|

Will the N55B30T0 fit my car?
Will the N55B30T0 fit my BMW F30 335i?
Yes, the BMW F30 335i left the factory with the N55B30T0, so an N55B30T0 from another car is the direct replacement. The sixth 3 Series was built 2011–2019, and the N55B30T0 was produced 2009–2016, 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.

Buying a used N55B30T0: checklist
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Electric water pump. This engine uses an electric water pump. It fails without warning and needs a diagnostic bleeding routine when it is replaced or the system is refilled.
Questions about the N55B30T0
What should I check on a used BMW N55 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 N55 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.
Ask the desk for more pictures of any listing. We are happy to show the stamp, the ports and the ancillaries before you decide. 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 hard is an N55 BMW swap?
A N55B30 swap into the BMW E36, BMW E46 and BMW E39 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: N55 turbo petrol conversions for older BMW chassis.
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.

What should I know about the BMW N55 engine?
BMW N55 3.0 single-turbo petrol engines for F30 335i, M135i and X5 35i. We list one version: N55B30 (3.0 liter (2,979 cc), 225 kW (306 HP), 2010 to 2017).
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 N55 family was used in chassis F30, F31, E92, F32, F20, F15 and F25. 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.

Which years were BMW N55 engines made?
BMW built the N55 engines we list from about 2010 to 2017. The N55B30 ran from 2010 to 2017.
They went into chassis F30, F31, E92, F32, F20, F15 and F25. 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.
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.

Is the BMW N55B30 a diesel or petrol engine?
The N55B30 is a petrol engine. It is a 3.0 liter (2,979 cc) inline 6, DOHC, 24 valve unit with a twin-scroll turbocharger, and it was built to the Euro 5 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.

How much power and torque does the BMW N55B30 have?
From the factory the BMW N55B30 makes 225 kW (306 HP) and 400 Nm of torque. It is a 3.0 liter (2,979 cc) inline 6, DOHC, 24 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 N55B30 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.
