Bmw 340i problems
The sixth generation of the BMW 3 Series consists of the BMW F30 (sedan version), BMW F31 (wagon version, marketed as 'Touring') and BMW F34 (fastback version, marketed as 'Gran Turismo') compact executive cars. The F30/F31/F34 generation was produced from October 2011 to 2019 and is often collectively referred to as the F30.
For the sixth generation, the coupé and convertible models were spun off to create the new BMW 4 Series nameplate. BMW also introduced a separate hatchback model under the 3 Series nameplate called the 3 Series Gran Turismo (F34).
The F30 is the first generation of 3 Series to be powered by a range of turbocharged engines exclusively and electric power steering (replacing the hydraulic power steering systems used previously). The F30 also marked the 3 Series' first use of a three-cylinder engine in its 2015 facelift. A new plug-in hybrid F30 model was also introduced in 2016. A long-wheelbase sedan version (model code F35) was sold in China.
The M3 model (designated F80) was introduced in 2014 and is powered by the S55 twin-turbocharged straight-six engine.
In March 2019, the BMW 3 Series (G20) was released as the successor to the F30. But the F34 fastback model continued to be available until early 2020. Later, it was replaced by BMW 4 Series Gran Coupé (G26) in June 2021.

Common Bmw 340i problems
The BMW 340i, a powerful and luxurious vehicle, has been reported to have several common problems by its owners. One of the most frequently mentioned issues is coolant loss, which can be caused by a faulty expansion tank cap or a damaged radiator. This problem can lead to engine overheating and potential damage, making it a significant concern for 340i owners.
Another common issue reported by 340i owners is the malfunctioning of the Apple CarPlay feature, particularly the maps and WhatsApp applications. These issues can manifest as small grid lines with no map detail or the inability to display messages, respectively. This can be frustrating for drivers who rely on these features for navigation and communication purposes.
The sunroof in the 340i has also been reported to produce squeaking or creaking sounds, which can be a source of annoyance for drivers and passengers. This issue can be caused by various factors, such as loose or worn-out components, and may require professional attention to resolve.
The steering wheel in the 340i has been reported to be misaligned, which can affect the driving experience and potentially cause safety concerns. This issue can be resolved by adjusting the tie rods, a process that may require the assistance of a professional mechanic.
The Harman Kardon Surround Sound system in the 340i has been reported to produce a hollow and boomy sound, which can detract from the overall driving experience. This issue can be caused by various factors, such as improper installation or component failure, and may require professional attention to resolve.
The transmission in the 340i has been reported to hang onto gears and produce theatrical downshift sounds, which can be a source of annoyance for drivers. This issue can be caused by various factors, such as software calibration or component failure, and may require professional attention to resolve.
The Cerium Grey mirror housings and wheels in the 340i have been reported to have different shades, which can detract from the overall appearance of the vehicle. This issue can be a source of frustration for drivers who value the aesthetic appeal of their vehicle.
In summary, the BMW 340i has several common problems that can affect the driving experience and potentially cause safety concerns. These issues include coolant loss, malfunctioning Apple CarPlay features, squeaking or creaking sunroofs, misaligned steering wheels, faulty Harman Kardon Surround Sound systems, recalibrated transmissions, and inconsistent Cerium Grey shades. While some of these issues can be resolved with simple adjustments or software updates, others may require professional attention and potentially costly repairs.
What is the common failure of B58?
A failed valve cover gasket is an issue that's plagued many BMW engines and the B58 is no exception. As the rubber material ages and goes through many heat cycles, it begins to degrade and perish. We advise owners to monitor the valve cover area for oil leaks, especially on higher mileage vehicles.
Is the BMW B58 engine reliable?
The consensus is that the B58 holds its own in terms of reliability, even compared to its Japanese and American counterparts.
Is a BMW 340i a good car?
In normal driving, this M340i feels very quick and effortlessly muscular. The combination of the turbocharged engine, the excellent transmission, and the hybrid system provides seamless power. Turbo lag is essentially nonexistent unless you floor the throttle from a dead stop.
Is the B58 one of the best engines?
The B58 engine was named to Ward's World's 10 Best Engines four times, in 2016 (installed in the 340i), 2017 (M240i), 2019 (X5) and 2020(M340i). The S58 engine, which was released in early 2019, is the high-performance version of the B58. It was named to Ward's World's 10 Best Engines in 2023 (installed in the M2).
