BMW 325i engine N52B25
Engine reliability and common problems:
On this engine, the valve seals and crankcase breather valve diaphragm tend to fail after 80-100 000 km, leading to increased oil consumption. It is recommended to choose engines manufactured in the last years of production (after 2010). The engine is not suitable for power boost modifications.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.

| 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. More service info |
| Timing chain change interval | 120,000 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. |
