WARNING: This page does not describe the selected car, but rather 14 other vehicles, including the 2013 BMW 328xi, 2013 BMW 328i, 2012 BMW 328xi, 2012 BMW 328i, and 2011 BMW 328xi. However, it is still accessible from the selected car via links, so may be relevant.

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: 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 .

The end faces of aluminium screws/bolts are painted blue for the purposes of reliable identification.

Jointing torque and angle of rotation must be observed without fail (risk of damage).

Necessary preliminary tasks:

Remove underbody protection with bracket at FRONT and REAR .
Remove FAN COWL
Remove complete EXHAUST SYSTEM
Remove front muffler (N53)
Remove heat shields
