Overall reliability and structural points
The BMW E60 is based on a chassis combining aluminium at the front and steel at the rear, in order to achieve a near 50/50 weight distribution. This design improves dynamic balance, but makes certain repairs (wings, front hood) more expensive, as they require an aluminium-certified workshop .
The facelifted (LCI) versions produced from March 2007 onwards benefit from numerous improvements:
-
Next-generation iDrive (CIC, smoother and more reliable than CCC)
-
electronically controlled automatic transmission (“shift-by-wire”)
-
adaptive headlights and modernized driver assistance systems
-
regenerative braking and new electronic control units
Overall, electronic reliability is acceptable , but the steering sensors, battery module (MPM) and iDrive system may have problems over time.
Reliability of BMW 5 Series E60 / E61 diesel engines
520d – 2.0 four-cylinder (M47 then N47)
The 520d is the most common model, particularly in France, because it combines favorable tax treatment with fuel efficiency. However, not all 520ds are created equal.
M47 (2003–2007)
The M47TU2D20 engine was fitted to the early models. It was an evolution of the M47 engine already well-known in the E46 3 Series.
The positive points:
-
Simple mechanics, timing chain at the front (easy to replace).
-
Excellent performance (163 hp for approximately 6 L/100 km real-world).
-
Decent performance, inexpensive maintenance.
Points to be aware of:
-
Swirl flaps : These flaps, located in the intake manifold, can detach and be drawn into the engine, causing serious damage. The solution is to remove them or replace them with reinforced versions.
-
Turbo and EGR valve : susceptible to fouling, especially on urban journeys.
-
Vacuum hoses and oil breather : to be replaced preventively every 100,000 km.
Verdict: a reliable and economical engine, perfect for high-mileage drivers if well maintained.
N47 (2007–2010)
The N47 engine replaced the M47 in the facelifted (LCI) version. More modern, it improved performance (177 hp then 184 hp on some versions) and reduced emissions, but it suffers from a major flaw.
Recurring problem: the rear timing chain.
Located on the gearbox side, it is extremely difficult to access.
-
Symptom: metallic noise when cold or idling , which intensifies over time.
-
Replacement cost: often more than €1,500, or even €2,000 at a dealership.
-
If the chain breaks, the engine is usually destroyed.
Verdict: performs well but requires close monitoring. It is essential to check if the timing chain has been replaced or if the engine has been made more reliable.
525d, 530d and 535d – 6-cylinder in-line M57
These engines are the benchmark for BMW diesels. Smooth, powerful and remarkably reliable, they represent the heart of the E60 5 Series range.
525d – M57TU then M57TU2 (177 to 197 hp)
-
177 hp versions (before 2007): engine identical to that of the 330d E46, very robust.
-
197 hp versions (after 2007): slight update to meet Euro 4 standards.
Points to watch out for:
-
Swirl flaps , like on the 520d: to be removed or made more reliable.
-
EGR valve and manifold: frequent fouling, cleaning recommended every 100,000 km.
-
Oil leaks at the rocker cover and crankcase.
Verdict: a fuel-efficient, balanced and durable engine, capable of handling very high mileage.
530d – M57N then M57N2 (218 to 235 hp)
This is undoubtedly the best diesel engine for this generation.
It combines power, comfort and exceptional longevity.
-
218 hp versions until 2007, then 231/235 hp on the last E60 LCI.
-

-
More expensive maintenance (two turbos, more sensors, specific diesel filter).
Verdict: an exceptional engine, reliable but reserved for enthusiasts aware of the maintenance cost.
Reliability of the petrol engines of the BMW 5 Series E60 / E61
520i – 2.2, 2.0 and 2.5 L (M54, N46 then N43)
The 520i has had several successive engine versions:
-
M54B22 (until 2005) : 2.2L inline 6-cylinder, smooth and reliable.
-
Monitoring of the cooling system (water pump, thermostat, expansion tank).
-
Frequent oil consumption, but not serious if monitored.
-
-
N46B20 (2005–2007) : 4 cylinders, more economical but less refined, sometimes noisy.
-
Intake coils and VANOS need replacing.
-
-
N43 (after 2007) : direct injection, decent performance, but fragile injectors and irregular idle on some examples.
Verdict: the 520i is reliable in its 6-cylinder versions (M54), but should be avoided in N43 if frequent urban use is required.
523i / 525i – M54 then N52 (2.5 to 3.0 L, 177 to 218 hp)
-
M54 : excellent mechanical base, already used on the E39.
-
Check the rocker cover gaskets and the coolant hoses.
-
VANOS actuators can weaken over time, causing a lack of power.
-
-
N52 (2005–2010) : more modern, all-aluminum block with variable valve timing (Double-VANOS and Valvetronic).
-
Reliability is quite good, but some suffer from noisy hydraulic tappets when cold , which were corrected after 2008.
-
Verdict: the 525i is an excellent compromise between reliability, smoothness and reasonable fuel consumption.
530i – M54, N52 then N53 (231 to 272 hp)
