Grinding noise when cornering
E46 / M3E60 / M5E63 / M6E64 / M6
Complaint:
Grinding noises from the area of the rear axle when cornering at low speed, especially
when turning at road junctions, when manoeuvring, parking or on roundabouts.
Cause:
Slip-stick-effect between pad and steel disk of the rear axle for differential speed between
the rear axle wheels.
Affected vehicles:
E46/M3
Manufacturing period: from start of series production until December 2003.
E60/M5, E63/M6, E64/M6
Manufacturing period: from the start of series production.
Procedure:
In case of customer complaint, replace the oil in the differential with a special oil.
The special oil is filled into 0.5 litre plastic bottles. The rear-axle final drive can be filled from
the plastic bottle without the use of an additional auxiliary pump - please refer to the
following illustration.
Tear off and remove the lead seal (1) between the thread on the bottle and the filler neck
stopper.
Pull on the stopper flap (2) and pull the filler neck (see arrow) from the bottle.
Unscrew the sealing cap (3) from the filler neck.
Insert the filler neck into the filler opening in the rear-axle final drive and position the bottle
below the driven shaft. Squeeze the bottle (4) to fill. Fill the rear differential unit until the
special oil escapes from the oil fill opening.
Then, with the engine warm, drive the vehicle in circles with as small a radius as possible
(20 full turns in each direction). This causes the special oil to penetrate between the lock
pad layers.
Depending on "driving style" and "road characteristics," it may take from 500 to 1000 km
for the effect of the special oil to become fully noticeable!
