X6 E71 BMW N57

- Critical severityFrequency: CommonTimingRear timing chain wearThe N57 inherits from the N47 the timing chain at the rear of the block, next to the gearbox, which complicates any repair. Unlike the N47, there is no documented campaign or wave of mass claims, and cases of serious wear appear mainly above 200,000 km.

X6 E71 BMW N62 / N63

- Critical severityFrequency: OccasionalTimingN63 timing chain stretch and guide breakageOn the N63 the timing chain can stretch and the sliding guide can break, leaving plastic debris in the sump and risking serious engine damage. We have found no European recall for this reason.
