If such work, for example maintenance and re‐
pair, is performed inexpertly, it could result in
consequential damage and thus constitute a
safety risk.
Parts and accessories
BMW recommends using parts and accessory
products that are specifically approved for this
purpose by BMW.
You are recommended to consult a BMW Serv‐
ice Partner for advice on genuine BMW parts and
accessories, other BMW approved products and
expert advice on all related matters.
The safety and compatibility of these products in
conjunction with BMW vehicles have been
checked by BMW.
BMW accepts product responsibility for genuine
BMW parts and accessories. BMW cannot ac‐
cept liability for parts or accessory products of
any kind which it has not approved.
BMW is unable to assess each individual product
of outside origin as to its suitability for use on
BMW vehicles without safety risk. Nor can suita‐
bility be assured if an official permit has been is‐
sued for it in a specific country. Tests performed
for such permits cannot always cover all operat‐
ing conditions for BMW vehicles, and some of
them therefore are insufficient.
Data memory
General
A number of electronic control devices are instal‐
led in your vehicle. Some of these are necessary
for the vehicle to function safely or provide assis‐
tance during driving, for example Driver Assis‐
tance Systems. There are also control devices
which manage comfort or infotainment functions.
Electronic control devices contain data memo‐
ries, which can temporarily or permanently store
information about the vehicle's condition, com‐
ponent use and wear, maintenance require‐
ments, technical events and faults.

Notes
This information generally documents the condi‐
tion of a component, a module, a system or its
environment, for example:
▷ Operating states of system components,
for example, fill levels, tyre inflation pressure,
battery status.
▷ Status messages of the vehicle and its indi‐
vidual components, for example wheel rota‐
tion speed, wheel speed, deceleration, lateral
acceleration, fastened seat belt indicator.
▷ Malfunctions and faults of important system
components, for example, lights and brakes.
▷ Information on vehicle-damaging events.
▷ Responses of the vehicle to particular driving
situations, for example, triggering of an air‐
bag, activation of the stability control sys‐
tems.
▷ Ambient conditions, for example temperature,
rain sensor signals.
The data is required to perform the control de‐
vice functions. It is also used for detecting and
rectifying malfunctions, and helps the vehicle
manufacturer to optimise vehicle functions. The
majority of this data is transient and is only pro‐
cessed within the vehicle itself. Only a small pro‐
portion of the data is stored in event or error
memories and, if necessary, in the vehicle key.
Reading out data
When service work is being carried out, for ex‐
ample repairs, service operations, warranty work
and quality assurance measures, this technical
information can be read out from the vehicle to‐
gether with the vehicle identification number. A
Service Partner of the manufacturer or another
qualified Service Partner or a specialist workshop
can read out the information. The legally required
on-board diagnostics (OBD) socket in the vehicle
is used to read out the data. The data is collec‐
ted, processed and used by the relevant organi‐
sations in the service network. The data docu‐
ments the technical conditions of the vehicle,
helps in locating faults and improving quality, and
