This 6-cylinder 24-valve engine camshaft is driven by chain (What is an engine chain and belt? ). Engine has fuel injection system, this is an atmospheric engine (without turbine). Engine versions compliant with Euro 4 and Euro 5 emission standards available. Engine lifespan (mileage before major repairs or overhaul) can last from 240 up to 410 thousand kilometres. Remember that engine life depends on regular maintenance and the quality of the materials used (oils, fuels, etc.).

Engine reliability and common problems:
The BMW N52 engine was the first water-cooled engine to feature a composite cylinder block made from a magnesium and aluminum alloy. It was included in Ward’s AutoWorld’s list of the top 10 engines in 2006 and 2007. While it offers many advantages, the engine is known to face several recurring issues.The smaller 2.5-liter version often suffers from oil consumption problems due to its thin piston rings, which quickly coke up and seize. Additionally, after 100,000 km, valve stem seals tend to harden, further exacerbating oil consumption. This issue was largely resolved in engines produced after 2007, but for earlier models, the solution is to replace the valve stem seals and piston rings.
Idle fluctuations are commonly caused by issues in the Valvetronic or Vanos systems, or by a malfunctioning mass airflow sensor. Proper diagnostics are required to identify the fault and replace the defective component. Another frequent issue is the failure of the crankcase ventilation valve (CCV) membrane, which can destabilize engine operation and requires timely diagnostics and replacement.
Engines produced between 2004 and 2009 often exhibit ticking sounds from the hydraulic lifters when cold. This noise is not a sign of failure but a characteristic of the design. Additionally, the engine is prone to overheating, necessitating careful monitoring of the cooling system, including the water pump, thermostat, and radiator, along with regular maintenance.
Valve cover gasket wear is another common issue, leading to oil leaks that require replacement. Despite its weaknesses, regular maintenance and timely resolution of problems can ensure stable and reliable performance from the N52 engine.
Overall, this engine can last around 240,000 to 410,000 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 | 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. |
