Important!
After completion of work, check transmission oil level.
Use only the approved transmission fluid.
Failure to comply with this requirement will result in serious damage to the automatic transmission!
Important:
E60/E61 and E63/E64 cars are equipped with the Auto-P function as from 03/07 and 09/07 respectively.
Consequence:
With ignition on and selector lever in N position, the P position (transmission parking brake) is automatically engaged after 30 mins.
This can be prevented by manually unlocking the transmission interlock [1][2]Manual Emergency Release of Transmission Lock.
Car must not be moved when the transmission interlock is engaged.
Failure to comply with this instruction will result in immediate transmission damage.
Important!
Aluminium-magnesium materials.
No steel screws/bolts may be used due to the threat of electrochemical corrosion.
A magnesium crankcase requires aluminium screws/bolts exclusively.
Aluminium screws/bolts must be replaced each time they are released.
Aluminium screws/bolts are permitted with and without color coding (blue).
For reliable identification:
Aluminium screws/bolts are not magnetic.
Jointing torque and angle of rotation must be observed without fail (risk of damage).
