BMW 340i xDrive (F30)

BMW 3 series 2015 3.0 petrol description

Sedan BMW 340i xDrive has been produced from January, 2015 to January, 2018. It has six-cylinder petrol engine with displacement of 3.0 litres, which produces power of 326 horsepower on 6500 rpm - this is the most powerfull BMW 3 sērija 2015 - 2018 version and torque 450 Nm (Newton metres) on 1380 revolutions per minute.

This 6-cylinder 24-valve engine camshaft is driven by chain (What is an engine chain and belt? ). Engine has fuel injection system and Twin-Scroll turbine. The engine meets the Euro 6 emissions standard. Approximate engine life expectancy (mileage until serious repairs are required) for this engine is between 210 000 and 360 000 kilometres. Remember that engine life depends on regular maintenance and the quality of the materials used (oils, fuels, etc.).

The B58 engine, compared to its predecessor, features a 20% increase in boost pressure, a closed-deck cylinder block design, an increased compression ratio of 11.0:1, and a slightly larger displacement of 2998 cc, up from 2979 cc, with an additional weight of 8  ...  This BMW 3 series 3.0 engine oil type is 0W-20, 0W-30, 5W-30 and oil capacity is 6.5 litres.

BMW 340i xDrive has AWD (all wheel drive) (power is automatically distributed between the wheel axles) and automatic gearbox with 8 gears. BMW xDrive is a proactive all-wheel drive system without a center differential that engages before the vehicle becomes destabilized, unnoticed by the driver. Torque is distributed between the axles by an electronically controlled multi-plate clutch in the transfer case. The clutch is partially locked at most times, distributing power to both axles in a 40/60 front/rear ratio, but the system is capable of sending 100% of the torque to either axle. At higher speeds or when parking, multi-plate clutch is disengaged and all power is transferred to the rear wheels. DSC system (Dynamic Stability Control) also brakes the wheels separately to regain traction and assist in cornering.
BMW 340i xDrive accelerates to speed 100 kilometres per hour in 4.9 seconds. The maximum speed of this car is 250 km/h.

In combined cycle (city and motorway), the BMW 340i xDrive fuel consumption is 7.3 litres per 100km (13.7 km/l), fuel consumption in city - 9.7 l/100km, highway fuel economy - 5.9 l/100km. Fuel tank capacity is 60 litres or 15.85 gallons, which gives a mileage up to 820 kilometers without refueling in urban cycle and even up to 1000 kilometers on highway.
According to user reviews, this BMW real everyday fuel consumption is 9.5 litres per 100 km, which is 30% more than the manufacturer's stated. More - Real BMW 3 series fuel consumption.

BMW 340i xDrive engine B58

Engine reliability and common problems:

The B58 engine, compared to its predecessor, features a 20% increase in boost pressure, a closed-deck cylinder block design, an increased compression ratio of 11.0:1, and a slightly larger displacement of 2998 cc, up from 2979 cc, with an additional weight of 8 kg. Despite its advancements, the engine has several common issues.

Coolant leaks are frequently reported, often linked to a drop in coolant levels without an obvious cause. In some cases, replacing the expansion tank cap resolves the issue. Head gasket failure is another recurring problem due to the engine's high operating temperatures. Symptoms include a strong smell of burning oil and sometimes visible smoke. Oil leaks are also common, originating from areas such as the oil filter housing, oil cooler, or head gasket. Prompt repairs are crucial to prevent oil starvation and potential engine damage.

The B58, like many direct-injection engines, often experiences carbon buildup on intake valves, leading to fluctuating idle and reduced performance. Less frequently, issues arise with the VANOS system, responsible for variable valve timing. Symptoms include power loss, uneven idle, stalling, and high fuel consumption. VANOS problems typically appear around 80,000–100,000 km. Oil filter disintegration is another concern, with parts of the filter sometimes breaking off and getting stuck in the housing. This can lead to oil leaks and other complications, often caused by low-quality filters or improper replacement.

Additionally, valve cover gaskets are prone to leaks, with symptoms such as the smell of burning oil, smoke, or low oil level warnings. Plastic valve covers can also crack over time. These issues usually arise between 60,000 and 100,000 km. Some BMW G-series models produced before 2021 may encounter failures in the oil pump due to a design flaw in the internal bushing. The recommended solution is upgrading to the sixth revision oil pump with a metal component.

Overall, while the B58 engine is a significant improvement in performance and efficiency, these known issues highlight the importance of regular maintenance, timely repairs, and the use of high-quality parts to ensure reliability.
Overall, this engine can last around 210,000 to 360,000 km if properly maintained, using the correct quality oil and fuel, and carrying out regular checks and maintenance.
The engine has hydraulic valve tappets (lifters), which provide quieter operation and do not require periodic adjustment, but are more complex in design and can cause serious engine damage in the event of failure.
Engine displacement 2998 cm3
Number of cylinders 6

Camshaft drive Timing chain

Chain motors are considered more reliable, chain replacement usually is required less often than a timing belt, but they are often louder and vibrate more.
