Important information
Customer information G (Part No. 01 29 2 467 469) must be given to the customer.
These installation instructions are primarily designed for use within the BMW dealership organization and by authorized BMW service companies.

All work must be completed using the latest BMW repair manuals, wiring diagrams, servicing manuals and work instructions, in a logical 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).

Note for the customer (important documents and information for the customer)
The workshop certificate (see appendix) must be completed and given to the customer with customer information G and the TÜV report/parts approval.
The customer must be told that a national acceptance procedure and an amendment of the vehicle’s paperwork are required because the brake system data relevant for the approval have changed. Correct installation must be confirmed by an officially approved expert or inspector.
The design characteristics of the perforated brake disks mean that they may generate noise during use; however this does not affect the stability of the brake system.
Run in the M Performance sport brake carefully for the first 200 km. After this, the full sporty characteristics of the brake system can develop.
