Differential noise & failure is a very common fault with the BMW 1 series and later 3 series as they use the twin tandem ball bearings on the diff pinion. The same applies for many other models since 2004.

Your problems normally start with a faint whine and as the bearings wear you will be able to vary the noise with the throttle pedal. KOYO bearing 7531620 03 / bmw koyo 7525256 03 / koyo japan 7537981 02

Eventually the bearing wear will cause total failure of the diff unit resulting in a worn or broken crownwheel & pinion set (Ring & Pinion).

It is advisable and cheaper to rebuild this type of BMW diff when the noise starts. koyo 7537980 02
