WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2013 BMW 128i, 2012 BMW 128i, 2011 BMW 128i, 2010 BMW 128i, and 2009 BMW 128i. However, it is still accessible from the selected car via links, so may be relevant.

Special tools required:

For the following special tools, refer to MAINTENANCE AND GENERAL INFORMATION - SPECIAL TOOLS -- 128I .

00 2 030
00 9 010
00 9 120
00 9 130
23 4 050 . See 23 4 050 UNIVERSAL TRANSMISSION BRACKET .

For the following special tools, refer to AUTOMATIC TRANSMISSION - SPECIAL TOOLS .

24 1 110
24 2 390
24 4 160
24 4 161
24 4 165

IMPORTANT: After completion of work, check transmission oil level . See 00 11 237 CHECKING/TOPPING UP FLUID LEVEL IN AUTOMATIC TRANSMISSION (GA6L45R) . Use only the approved transmission fluid. Failure to comply with this requirement will result in serious damage to the automatic transmission!

IMPORTANT: Aluminum-magnesium materials. No steel screws/bolts may be used due to the threat of electrochemical corrosion. A magnesium crankcase requires aluminum screws/bolts exclusively. Aluminum screws/bolts must be replaced each time they are released. Aluminum screws/bolts are permitted with and without color coding (blue). For reliable identification: Aluminum screws/bolts are not magnetic. Jointing torque and angle of rotation must be observed without fail (risk of damage) .

Necessary preliminary tasks:

Disconnect battery negative lead . See 61 20 900 DISCONNECTING AND CONNECTING BATTERY NEGATIVE LEAD .
