2007-2013：
Recalls:
•In September 2011, a recall was issued for BMW E70 X5 models with turbo-diesel engines that were available for sale from 20 August 2008 to 12 June 2009. In these vehicles, moisture may enter the diesel fuel filter heater at the electric contacts, causing the heater to short circuit – this could result in the short-term discharge of the starter battery such that the vehicle may not start. However, the short-circuit could also lead to an engine fire when the vehicle was switched off. Note that the diesel fuel filter heat unit only operated at temperatures below -1 degree Celsius (PRA 2011/13091).
•In November 2011, a recall was issued for BMW E70 X5 models with 4.4-litre twin-turbo V8 petrol engines that were available for sale from 16 November to February 2011. In these vehicles, fuel additives in plastic components in the additional coolant pump for the exhaust turbocharger may cause electromigration on the PCB (printed circuit board). As a result, the coolant pump may short circuit – this could also cause overheating and scorching on the coolant pump and a possible fire in the engine compartment (PRA 2012/13086).
•In February 2013, a recall was issued for BMW E70 X5 vehicles that were fitted with BMW’s N62 V8 petrol engine and available for sale prior to March 2010. In these vehicles, engine oil which entered the brake booster may damage the internal rubber membrane – as a result, the membrane may develop a leak which would impair the brake power assistance system. In turn, the driver may only be able to slow the vehicle by applying an increased level of brake pedal pressure (PRA 2013/13472).
•In August 2013, a recall was issued for BMW E70 X5 vehicles with turbo-diesel engines that were available for sale from 1 August 2009 to 30 November 2009. In these vehicles, an internal short-circuit may occur in the area of the electric contacts of the diesel fuel filter heating unit. At worst, an electrical short-circuit may occur in the diesel fuel filter heater which could could a vehicle fire. Please note, however, that hte diesel fuel filter heater unit only operated at temperatures below -1 degree Celsius. For the VINs of the recalled vehicles, please see PRA 2013/13591.
•In June 2014, a recall was issued for BMW E70 X5 vehicles that were powered by BMW’s N55 six-cylinder turbocharged petrol engine (i.e. the X5 xDrive35i) and available for sale from 1 October 2009 to 30 April 2012. In these vehicles, the bolted connection on the housing of the variable valve timing unit (VANOS) adjustment units could become loose. If this occurred, the units may develop an internal oil leak and then no longer adjust quickly enough due to the reduced oil pressure. The vehicle's emergency engine mode would then be activated and the engine warning light would illuminate to warn the driver. If the vehicle was being driven and slowed down or stopped unexpectedly, it would pose an accident hazard to the driver and other road users (PRA 2014/14160).
Problems and faults:
X50 3.0d and 3.0sd: M57TU2D30 swirl flaps
•For E70 X5 3.0d and 3.0sd models with the M57TU2D30 engines, the swirl flap mechanism in the inlet manifold consisted of butterfly valves within each individual inlet tract. These butterfly valves were secured to an actuating rod via two small screws and, over time, these screws could become loose. If this occurred, the screws could be drawn into the cylinder and cause significant damage to the piston, cylinder head and valves. If a screw were to pass through the exhaust valve, it could then damage the turbocharger. As a result of this problem, a common modification is to remove the swirl flaps and replace them with blanking plates. From 2004 to 2007, BMW introduced larger diameter spindles (made from plastic) and larger screws, though these engines were not immune to failure. Around 2006, it is understood that plastic swirl flaps were introduced to reduce the likely extent of damage.
X5 3.0si: N52 ticking noise
•E70 X5 3.0si models with N52 engines that were produced prior to November 2008 were susceptible to ticking noises from the hydraulic valve adjuster (HVA) during cold engine starts or frequent short-distance driving. In these situations, the HVA elements may not have sufficient amounts of air-free oil. The condition usually remedies itself with a longer driving distance or operating times at full operating temperature. Vehicles produced after November 2008, however, were fitted with an improved cylinder head that overcame the problem.
X5 3.0si and xDrive30i: N52 fuel pump
•In the USA in October 2010, a recall was issued for E70 X5 vehicles that had 3.0-litre N52B30 six-cylinder petrol engines and were manufactured from 1 November 2007 to 31 August 2008. In these vehicles, the fuel pump was not produced to specifications and, under specific operating conditions, the fuel pump’s commutator could experience an increase in wear – this wear could lead to fuel pump malfunction and engine stalling, such that the steering and brakes would lower power assistance (but remain operational). As such, the recall involved replacement of the in-tank fuel pump. For Australia, however, no recall has been issued.
Problems and faults: BMW E70 X5
•Seemingly unrelated electrical problems may be due to a loose power connector to the power distribution/electronics junction or box.
•In cold environments, moisture in the PCV system may turn to ice, causing the valve cover to crack and possibly leading to engine damage.
•The glove box may not fully open or close due to problems with the latch.
•For models with the sports suspension package, a knocking noise from the front suspension may be attributable to the sway bar.
•Water may leak from the upper section of the tailgate due to hinge bolts coming loose. Furthermore, the ‘tailgate ajar' warning or rattling of the tailgate may occur due to the latch striker not being properly aligned.
•The windscreen washer fluid reservoir may empty itself due to a siphoning action created in the breather while driving; a redesigned reservoir was subsequently released.
