Engine reliability and common problems:
The BMW N43 engine is built around a lightweight alloy cylinder block with a twin-cam, 16-valve head. It uses a dual-pump fuel delivery system—one located inside the tank to transfer fuel and supply the high-pressure pump, which then boosts fuel pressure up to 200 bar. Notably, the system lacks a fine fuel filter and relies only on a basic mesh filter in the tank.This engine uses direct fuel injection, and many of its recurring problems are tied to that system. Poor-quality fuel quickly damages the expensive injectors, which are often the root cause of hard cold starts. Many owners report that the engine refuses to start in the morning, and in most cases, the only long-term solution is replacing all injectors with the latest revision.
Misfires and uneven engine operation may also stem from faulty ignition coils. The engine runs hot, making it particularly sensitive to oil quality—cheap oil can degrade quickly under such conditions. Plastic coolant flanges and hoses are prone to cracking and should be monitored closely.
Another weak point is the vacuum pump, which frequently begins leaking and requires replacement as early as 70,000 km. The timing system, especially the Double VANOS components, is known for its limited durability.
The exhaust system is another frequent source of trouble. It includes a NOx storage catalyst and sensor. The catalyst stores nitrogen oxides and periodically burns them off in a regeneration process. As the car ages, this regeneration becomes more frequent, particularly the burn-off of sulfur deposits. However, regeneration requires sustained highway speeds—NOx regeneration activates around 80 km/h, while sulfur regeneration only starts near 100 km/h and takes significantly longer.
Failure to regenerate leads to fault codes and eventual failure of the NOx sensor, which is expensive to replace. Oil leaks are common over time, as is typical for many N-series engines. Valve cover gaskets, oil filter housing gaskets, VANOS solenoids, and vacuum pump seals all tend to require replacement eventually.
Coolant flange leaks are also common. These parts are made of plastic and tend to develop cracks at the joints over time. Fortunately, replacements are inexpensive and easy to source.
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.

| Timing chain change interval | 150,000 km (recommended) Sometimes manufacturers do not specify timing chain replacement intervals and design chains for engine life. However, once the recommended change interval has been reached, it is recommended to periodically check the condition of the chain and to change the chain if excessive stretching is detected or if unusual noises from the engine or other symptoms occur. |
