The installation time is approx. 0.75 hours. This may vary depending on the condition of the car and its equipment package.
The installation time shown does not include any time spent on programming/coding.
The calculation of the total costs for the programming time must be factored into the calculation of retrofitting costs (must not be invoiced under the warranty).
These installation instructions are primarily designed for use within the BMW dealership organisation and by authorised BMW service companies.
These installation instructions are intended for use by qualified specialist staff trained on BMW vehicles with the relevant expert knowledge.
All work must be completed using the latest BMW repair manuals, wiring diagrams, servicing manuals and work instructions, in a rational order, using the prescribed tools (special tools) and observing current health and safety regulations.
If you experience installation or function problems, restrict troubleshooting to approx. 0.5 hours for mechanical work and 1.0 hour for electrical work.
To avoid unnecessary extra work and/or costs, send an inquiry straight away to the technical parts support team via the Aftersales Assistance Portal (ASAP).
Quote the following information:
- Chassis number,
- Retrofit kit part number,
- A detailed description of the problem, – and any work already carried out.
Do not archive the hard copy of these installation instructions since daily updates are provided via ASAP.
All pictures show LHD cars; proceed in the same way on RHD cars.
Some of the installation is shown only on the left-hand side of the car; proceed in the same way on the right-hand side of the car.
Ensure that the cables and/or lines are not kinked or damaged as you install them in the car. Costs arising from this will not be reimbursed by BMW AG.
Additional cables/lines that you install must be secured with cable ties.
To order, a decorative trim without a switch for the steering wheel heating can be installed. This is not included in the retrofit kit and must be ordered separately (7 856 290). In addition the multi-function keys must be installed in the new decorative trim as described in AIR.
All cables, lines and control units must be taken from the standard M sport steering wheel.
Information for the workshop
When installing the M Performance steering wheel in cars with steering wheel heating SA 248, the heating function will no longer work. It does not need to be decoded. The switch for steering wheel heating remains nonfunctional. The error memory message can be ignored.
