About this model
The second-generation BMW X5 (E70, 2006-2013) is one of the most popular luxury SUVs on BiH roads. In BiH it is mostly imported from Germany, Switzerland and Austria, usually as the 3.0d diesel variant with an automatic gearbox and all-wheel drive. A typical example on the local market has between 200,000 and 300,000 km, a production year of 2007-2012 and comes well equipped. The E70 is a significant step up from the E53 predecessor, with the iDrive system, optional LED headlights and a more comfortable ride. However, that complexity also brings higher maintenance costs. The 3.0d diesel version with the M57TU2 engine (until 2010) or the N57 engine (LCI from 2010) offers a good balance of power and fuel economy for an SUV weighing over 2 tonnes, but demands a disciplined service schedule. On the BMW service Banja Luka page you can see the services we offer for this brand.
Engines and variants
This model is most commonly available in BiH with the following engines.
M57TU2D30 (235 HP, 3.0d / xDrive30d): An inline six-cylinder diesel with 3.0-litre displacement, a single Garrett GTB2260VK turbocharger and 520 Nm of torque. This is the most common variant on the BiH market and the most popular import choice. The electric water pump and EGR cooler are two key problems specific to this version, along with oil leaks from the valve cover. The timing chain sits at the front of the engine, which makes access easier and lowers replacement costs compared to the N57. Parts availability is good because the same engine is used in the E60, E90 and E65.
M57TU2D30 (286 HP, 3.0sd / xDrive35d): An uprated version of the same M57TU2 block with a twin-scroll turbocharger and 580 Nm of torque. Less common in BiH but present, particularly among imports from Switzerland and Germany. The larger turbocharger is under even greater stress than on the 235 HP version, so VGT vane wear and turbo oil leaks are more frequent issues. Fuel consumption is slightly higher, but the power difference is noticeable under full load and when towing.
N57D30O0 (245 HP, xDrive30d LCI): The new-generation diesel with an aluminium block, single turbo and 540 Nm. A facelift version with improved efficiency and lower emissions. The timing chain at the rear of the engine is the main problem with this variant. Unlike the M57TU2 where the chain is at the front and accessible, on the N57 the engine needs to be raised or the gearbox removed for a chain replacement, significantly increasing the cost. The aluminium block is lighter but more sensitive to overheating.
N57D30T0 (306 HP, xDrive40d LCI): The bi-turbo version of the N57 engine with 600 Nm of torque. The most powerful diesel in the E70 range, rare but present in BiH among higher-end buyers. Two turbochargers mean double the chance of a turbo failure, plus the same rear-mounted timing chain issue as the 245 HP version. Maintenance costs are the highest of all diesel variants.
Reliability and reputation on the BiH market
The X5 E70 3.0d has a reputation in BiH as an excellent car to drive but a demanding one to maintain. In our workshop we most often see examples where previous owners ignored regular services and used BMW's longlife service regime on lower-quality fuel, resulting in premature turbocharger wear, a coked-up EGR system and timing chain problems. By contrast, examples with regular services at 10,000 km intervals and a complete history routinely exceed 300,000 km without major work.
Parts for the M57TU2 engine are well available because the same engine is shared with the E60, E90, E65 and Range Rover Sport. N57 parts are somewhat more expensive and less available on the local market. SUV-specific components such as the transfer case, air suspension and Dynamic Drive system are expensive and usually ship from Germany with a 5-10 day lead time. Most owners in BiH are men aged 35-55 who use it as a family car for longer trips, which suits this engine's character.
Compared to the Mercedes ML W164, the main rival in this segment, the X5 E70 offers better on-road behaviour but requires a more experienced mechanic and a larger maintenance budget. The average owner in BiH drives 15,000-20,000 km per year, which is enough for regular DPF regenerations if it includes out-of-town trips.
Common faults we see
From our hands-on experience, here is what most often comes in for repair on this model.
1. Transfer case actuator
Symptom: 4x4, ABS and DSC warning lights on the dashboard, clicking noise from underneath the car when the ignition is switched off, inability to change drive modes.
The E70 uses an ATC700 transfer case with an electric motor actuator. Inside the actuator is a plastic gear that wears down and loses teeth, typically between 120,000 and 180,000 km. This is an inherited design flaw also present on the E53 generation, although the E70 uses a different assembly (ATC700 instead of the E53's ATC500). The fault does not appear suddenly - it usually starts with intermittent warning lights that clear after restarting the engine.
Advice: An aftermarket metal gear for the actuator costs far less than a complete case replacement. The swap is done without removing the entire transfer case. If you notice clicking when the ignition is switched off, that is an early symptom you should not ignore.
2. Electric water pump
Symptom: Engine overheating with no prior warning, "Engine overheating" message on the iDrive screen, sudden coolant loss.
Unlike the E53, the X5 E70 with the M57TU2 engine uses an electric water pump instead of a mechanical one. This pump operates independently of engine speed, which is an advantage for cooling, but it fails without warning. There is no gradual weakening as with a mechanical pump. When the pump stops, the engine overheats within minutes, and on an SUV weighing over 2 tonnes the consequences of overheating are serious. The problem is more common on examples with 150,000-200,000 km. You can read more about symptoms and preventive replacement in our guide on water pumps and when to replace them.
Advice: The electric water pump is a preventive replacement at around 120,000-150,000 km. Always replace the thermostat and expansion tank at the same time, as both are prone to failure in the same mileage range on this engine.
3. EGR cooler leak
Symptom: White smoke from the exhaust on startup and while driving, coolant loss with no visible external leak, sweet smell from the exhaust.
The EGR cooler on the M57TU2 engine develops internal cracks that allow coolant to enter the exhaust system. The smoke looks like a blown head gasket, but the head is usually fine. The problem is specific to the E70 generation because the greater vehicle mass means the engine spends longer periods under higher load, thermally stressing the EGR system and its cooler. Diagnosis requires experience because the symptoms mimic a more serious fault.
Advice: Before concluding a head gasket failure, inspect the EGR cooler with an endoscope or a pressure test. Replacing the EGR cooler is a considerably simpler job than replacing the head gasket.
4. Timing chain - N57 engine
Symptom: Rattling or droning from the rear of the engine on cold start, vanos fault (eccentric shaft sensor), rough idle.
The N57 engine (from 2010 in the E70 LCI) has the timing chain mounted at the rear of the engine, towards the gearbox. The chain stretches and the guides wear. Unlike the M57TU2 where the chain is at the front and relatively accessible, on the N57 the engine needs to be raised or the gearbox removed for replacement. The problem typically appears after 150,000 km, particularly on examples serviced on longlife oil intervals. Replacement is a major job that requires an experienced mechanic and more labour hours.
Advice: If you hear rattling from the engine area on cold start that disappears after warm-up, do not delay diagnostics. A stretched chain that skips a tooth can destroy the engine.
5. Turbocharger - VGT vane wear
Symptom: Loss of power during acceleration, exhaust smoke, whistling from the engine bay, boost pressure too low fault (P0299).
The M57TU2 engine has a Garrett GTB2260VK turbocharger with variable geometry. The VGT vanes stick due to soot and oil build-up, especially on vehicles driven mostly on short urban trips. As a heavier vehicle, the X5 requires more boost pressure than a saloon with the same engine, so the turbo operates under greater stress. On the 286 HP version (3.0sd/xDrive35d) the problem is even more pronounced due to the larger turbocharger.
Advice: Periodically load the engine on the open road (longer drives at higher RPM) to keep the VGT mechanism moving freely. If the vanes are already stuck, cleaning is possible without a full turbo replacement.
6. Front axle active stabiliser
Symptom: Clunking from the front over bumps, "Chassis and suspension" message on iDrive, the car leans more in corners than before.
The E70 has an optional active stabiliser (Dynamic Drive) with hydraulic actuators on the front and rear axles. The actuators leak oil, sensors fail and the hydraulic lines develop leaks. The system is complex because it uses a separate hydraulic pump, sensors and ECU. Many E70s in BiH have this system because it was included in higher equipment packages, but not all examples do. Repair is expensive because it requires specialist parts and experience with hydraulic systems.
Advice: Checking the Dynamic Drive system is essential when buying. If the system is not working, converting to conventional stabiliser bars is an option that eliminates the complexity and reduces maintenance costs.
7. Air suspension - rear axle
Symptom: The car drops at the rear overnight, the air suspension compressor runs constantly or not at all, uneven ride height from left to right.
Many E70 examples in BiH come with air suspension on the rear axle. The air springs leak at the seams, height sensors fail and the compressor (located under the boot floor) burns out from overwork. The system uses a newer generation of components than the E53, with better durability. Still, after 12-15 years and 200,000+ km, most examples have at least one issue with this system.
Advice: Leave the car for 12+ hours and check whether it sits level. If it has dropped on one side, the air spring on that side is leaking. Converting to conventional coil springs is a popular swap in BiH that permanently solves the problem.
8. Oil leaks - valve cover and oil filter housing
Symptom: Burning smell from the engine bay, visible oil drips underneath the car after standing, smoke from the top of the engine on longer drives.
The valve cover gaskets and oil filter housing seals on M57TU2 and N57 engines harden and begin leaking after 150,000-200,000 km. Oil drips onto the exhaust manifold and the smoke is drawn into the cabin through the ventilation. On the X5 the problem is more pronounced than on a saloon because the higher engine load generates more heat in the engine bay. The leak is visually noticeable when inspecting the top of the engine.
Advice: Replacing the oil filter housing seal and valve cover gasket are preventive jobs best done together. Do not ignore a burning smell, as oil on a hot exhaust is a potential hazard.
Service and maintenance
The M57TU2 engine uses a timing chain at the front that does not require scheduled replacement, but the N57 has a chain at the rear that should be inspected after 120,000-150,000 km. We recommend 5W-30 oil meeting BMW LL-04 spec with a change interval of 10,000 km - never the 25,000-30,000 km longlife interval on BiH fuel. The ZF 6HP26/6HP28 automatic gearbox requires an oil and filter change every 50,000-70,000 km, despite BMW's claim that the oil is lifetime fill. Transfer case oil should be changed every 40,000-60,000 km. The DPF filter requires regeneration achieved through longer drives on the open road. A short urban driving pattern accelerates DPF clogging and can lead to forced regeneration or replacement.
Owner tips
- Use 5W-30 oil meeting BMW LL-04 spec and change it at 10,000 km. Longlife intervals of 25,000 km are not suitable for BiH fuel and driving conditions.
- Check the history before paying a deposit: use the VIN to pull the full history via carVertical. From international registries you get real odometer readings by date, recorded accidents, number of previous owners and theft or total-loss indicators. We consider this essential before buying any used car, especially German imports. When paying for the report you can use the code GAGA for a 20% discount.
- Replace coolant every 2 years and check the electric water pump at every service, as it fails without prior warning.
- Change the oil in the ZF automatic gearbox at 50,000-70,000 km with genuine ZF LifeGuard 6 fluid and ignore BMW's lifetime fill recommendation.
- Drive at least once a week for 30+ minutes on the open road so the DPF filter can complete a regeneration. Exclusively urban driving accelerates clogging and shortens filter life.
Frequently asked questions
Is the BMW X5 E70 3.0d reliable at 250,000 km?
With regular services at 10,000 km, the M57TU2 engine comfortably reaches 300,000+ km. The key is avoiding the longlife interval on BiH fuel and preventively replacing the water pump around 120,000-150,000 km. Major costs arise when maintenance is neglected.
Which engine is a better choice in the X5 E70 - M57 or N57?
The M57TU2 (until 2010) is simpler to maintain because its timing chain sits at the front of the engine and is easier for a mechanic to reach. The N57 (from 2010) is more economical and quieter, but the rear-mounted chain makes replacement expensive. For BiH conditions, the M57TU2 with 235 HP is the most practical choice.
Is it worth fitting LPG to a BMW X5 E70?
On the petrol version of the X5 E70 (4.8i or 3.0si) an LPG conversion is worthwhile due to the high fuel consumption. LPG cannot be fitted to the diesel version. If you are interested in a conversion for the petrol version, get in touch for a quote.
How much does annual X5 E70 maintenance cost in BiH?
Routine maintenance (oil, filters, brakes, minor consumables) on the X5 E70 is more expensive than on a standard saloon because the car uses larger oil quantities, bigger brake discs and model-specific filters. Plan for a higher budget than for an E90 or E60 with the same engine.
Should I avoid an X5 E70 with air suspension?
Not necessarily, but air suspension requires extra attention. Check whether the car sits level after standing overnight. If it drops, the air spring is leaking. Converting to conventional coil springs is a popular option that eliminates that risk.
Is the ZF gearbox in the X5 E70 reliable?
The ZF 6HP26/6HP28 automatic gearbox is one of the more reliable automatics on the market, but only with regular oil changes at 50,000-70,000 km. BMW claims the oil is lifetime fill, but from experience we know that a gearbox without an oil change struggles to survive 200,000 km without juddering.
What to look out for when buying an X5 E70?
Be sure to check the transfer case (4x4 warning lights), air suspension (does it sit level), turbocharger condition (smoke on acceleration) and service history. Use the VIN to verify the real mileage, as X5s from Germany are a common target for odometer rollback.
