BMW 118i engine B38
Engine reliability and common problems:
The B38 1.5-liter three-cylinder petrol engine, introduced in 2013, was designed with a focus on fuel efficiency and low emissions to meet modern environmental standards. While it received generally positive feedback, it isn’t without issues.Common problems include rapid wear of the timing chain, injection system malfunctions, and occasional short circuits in the wiring harness. Overheating has also been reported, and in some cases, it leads to serious engine damage. BMW has addressed many of these issues in later production versions, improving reliability over time.
A known structural weakness is the turbine housing, which is made of aluminum and integrated with the exhaust manifold. Subject to high thermal loads, it can develop cracks that result in coolant leaks.
As with most direct injection engines, carbon buildup on intake valves is a typical issue. This leads to rough idle and unstable performance, often described as “fluctuating revs.”
Other weak points include the relatively short-lived catalytic converter and the EVAP purge valve. At higher mileage, failures in the VANOS and Valvetronic systems also become more common.
Despite its compact size and three-cylinder layout, the B38 responds well to chip tuning. With a proper remap, output can be increased from the stock 136 hp to over 170 hp, and torque from 220 Nm to more than 280 Nm, significantly enhancing the car’s performance.
Overall, this engine can last around 220,000 to 370,000 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.
