Faults that affect the X3 F25
- Critical severityFrequency: Very frequentTimingRear timing chain stretch and breakageYes: the N47 has its timing chain at the rear of the engine, next to the gearbox, and on a very high proportion of units, especially those built between 2007 and 2009, it stretches or breaks prematurely because of an inadequate tensioner, with a risk of destroying the engine.Repair (garage): €1,590–€3,000Appears at around 50,000 km
- Critical severityFrequency: CommonIntakeBroken intake manifold swirl flapsYes: the N47's intake manifold has plastic swirl flaps that, with diesel soot and the passing years, can crack, come loose and be sucked into the cylinder, with a risk of seriously damaging the piston, cylinder head and valves.
- High severityFrequency: CommonTurboTurbo and wastegate valve failureThe N47's turbo does not usually fail from general wear, but because of failure of the wastegate valve, which regulates boost and can seize or lose adjustment, sending fuel consumption soaring; oil leaks from the turbo itself are also common.Repair (garage): €900–€1,800
- Medium severityFrequency: CommonEmissions controlClogged or seized EGR valveYes, as on most diesels of its generation: the N47's EGR valve seizes or clogs with carbon, especially on cars used in town, causing an unstable idle, jerking and loss of power; it is not usually a serious fault if it is cleaned or replaced in time.Repair (garage): €400–€1,500
- Medium severityFrequency: CommonClutchDual-mass flywheel wear (manual gearbox versions)Yes: on manual-gearbox BMW N47s, the dual-mass flywheel can wear, especially after a lot of town mileage or driving in high gears at low revs; the typical symptoms are vibrations, a metallic rattle at idle and jerking when pulling away.Appears at around 150,000 km
