Important notes
(Only for use within the BMW trading organisation).
Installation time is approx. 6.5 hours which can vary according to the condition and fittings of
the vehicle.
Target Group
Target group for these installation instructions are technical personnel who have been trained
on BMW vehicles.
All maintenance, repair, installation and resetting work should be carried out on own authority.
All operations should be carried out with the aid of the current BMW
- repair instructions
- maintenance handbooks
- job instructions
in a rational sequence with the prescribed tools (special tools) whilst observing the current
safety regulations.
Safety instructions
The supplementary wiring harness and the installation instructions are designed only for left-
hand drive models. Should given PIN spaces be assigned, bridges, double crimping or parallel
connections will have to be made.
Tightening torques for screw connections should be adhered to without fail.
Installation notes
BMW accepts no liability for damage which occurs as a result of not following the work
sequence and safety instructions. In addition, any warranty claim against BMW AG is
extinguished in the event of improper fitting and handling which diverges from the fitting and
operating instructions.
At times operations are shown as carried out on only one side of a vehicle. Operations on the
other side of the vehicle should be carried out in a corresponding way.
When working on the outer skin panel of the vehicle, make sure that no permanent damage
occurs (scratches, pressure marks, etc). If necessary, cover sections of the vehicle outer skin
panel with protective film or similar.
Cable installation
To avoid interference keep to the prescribed installation routes in the vehicle.
Never work with so-called "Scotchlock quick connectors" as these can trigger faults in the
on-board electronics.
Make sure when installing cables that they do not get kinked or damaged, otherwise faults
may occur which can only be localised and remedied later by extensive reworking. Costs
arising in this way will not be reimbursed by BMW.
To avoid faults and short circuits by inadvertent touching of bare cable ends and by
working on current-carrying cables, the battery should be disconnected before work starts.
