Buying a used B58B30: checklist

1. 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.
2. 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.
3. 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.
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. 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 B58B30

How do I know a used B58B30 engine is in good shape?

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. 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 petrol engine like the B58B30, a careful fitter will also look at the spark plugs, the coils and the timing side 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 should I replace when I fit a used B58B30 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. Clean the intercooler and the intake pipes, and fill the turbo oil feed with clean oil before the first start, so the turbo never runs dry. Change the drive belt, the thermostat and the water pump seals if they look tired, because they are cheap while the engine is out.

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.

Will the B58B30 engine fit my BMW G01 X3 M40i?

Yes, if your BMW G01 X3 M40i was built with the B58B30. BMW used this 3.0 liter (2,998 cc) petrol engine with 250 kW (340 HP) in the G01 X3 M40i from about 2015 to 2020.

Some G01 X3 M40i cars were built with a different engine: the B58B30M1. These look alike from the outside, so check the code on your engine or send us your VIN.

Your car has all-wheel drive or is an X model, so the sump, the oil pickup and some brackets can differ from the rear-drive cars. Tell us the full model so we send the right set-up.

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.

Which cars use the BMW B58B30 engine?

BMW fitted the B58B30 to the BMW F30 340i, BMW G30 540i, BMW G11 740i, BMW G05 X5 xDrive40i and BMW G01 X3 M40i. These cars were built with this engine from about 2015 to 2020.

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.

Other engines in the same B58 family are the B58B30M1 (374 HP). They look alike but differ in power, parts and electronics, so they are not always a direct swap.

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 is the difference between the B58B30 and other B58 engines?

The B58B30 makes 250 kW (340 HP) and 500 Nm. The other B58 engines are: B58B30M1 with 275 kW (374 HP) and 500 Nm (2019 to 2026).

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.

Yes. We sell conversion kits that fit the B58B30 into the BMW E46. The kit replaces the M54, N52 and N55, and works with the ZF 8HP and ZF GS6-53.

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.

Tell us your BMW E46's year and current set-up, and we suggest the right parts. 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.

Will the B58B30 engine fit my BMW G05 X5 xDrive40i?

Yes, if your BMW G05 X5 xDrive40i was built with the B58B30. BMW used this 3.0 liter (2,998 cc) petrol engine with 250 kW (340 HP) in the G05 X5 xDrive40i from about 2015 to 2020.

Some G05 X5 xDrive40i cars were built with a different engine: the B58B30M1. These look alike from the outside, so check the code on your engine or send us your VIN.

Your car has all-wheel drive or is an X model, so the sump, the oil pickup and some brackets can differ from the rear-drive cars. Tell us the full model so we send the right set-up.

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.

The yard checks the code, records what is bolted on, and seals the openings before the engine is offered.

How much power and torque does the BMW B58B30 have?

From the factory the BMW B58B30 makes 250 kW (340 HP) and 500 Nm of torque. It is a 3.0 liter (2,998 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 B58B30 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.

Does a used B58B30 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.

Is the BMW B58B30 a diesel or petrol engine?

The B58B30 is a petrol engine. It is a 3.0 liter (2,998 cc) inline 6, DOHC, 24 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.
