32 13 075 Removing and installing electrical steering box (vehicles with active steering)

WARNING: This page does not describe the selected car, but rather 31 other vehicles, including the 2015 BMW Alpina B7L, 2015 BMW Alpina B7, 2015 BMW 750i, 2015 BMW 750Li, and 2015 BMW 740i. However, it is still accessible from the selected car via links, so may be relevant.

IMPORTANT:

Connecting line:

In the event of moisture/corrosion inside the two plug connections, check the insulation of the connecting line. If the insulation reveals any noticeable/striking features, partial replacement will be necessary. Otherwise it will be sufficient to replace the contacts or connector housing.

NOTE: In a warranty case you must always provide a fault memory printout, even where there is no fault entry, with the defective part.

Necessary preliminary work:

Disconnect BATTERY EARTH LEAD
NOTE: High-current-carrying wiring laid with permanent positive connection (80 A fuse).
Remove underbody protection at FRONT and REAR
Remove COVER FOR STEERING ASSEMBLIES on left and right
Remove TRACK ROD END on both sides from swivel bearing
Remove LOWER SECTION of steering shaft from steering box
Vehicles with Dynamic Drive:
- Remove ANTI-ROLL BAR LINK ON RIGHT OF ANTI-ROLL BAR

IMPORTANT:

To avoid the need for axle/wheel alignment, mark position of steering box (1) to front axle support (2).

To do so, draw a wide white stripe on the front bolting points (left and right) and apply a thin black marking (3) to this stripe.
