Maintenance
Maintain the vehicle regularly to sustain the
road safety, operational reliability and the New
Vehicle Limited Warranty.
Specifications for required maintenance meas‐
ures:▷BMW Maintenance system▷Service and Warranty Information Booklet

Data memory
Many electronic components on your vehicle
are equipped with data memories that tempo‐
rarily or permanently store technical informa‐
tion about the condition of the vehicle, events
and faults. This technical information generally
records the state of a component, a module, a system or the environment:
▷Operating mode of system components, fill
levels for instance.▷Status messages for the vehicle and from
its individual components, e.g., wheel rota‐
tion speed/vehicle speed, deceleration,
transverse acceleration.▷Malfunctions and faults in important sys‐
tem components, e.g., lights and brakes.▷Responses by the vehicle to special situa‐
tions such as airbag deployment or engag‐
ing the stability control system.▷Ambient conditions, such as temperature.
This data is purely technical in nature and is
used to detect and correct faults and to opti‐
mize vehicle functions. Motion profiles over
routes traveled cannot be created from this
data. When service offerings are used, e.g., re‐
pair services, service processes, warranty
claims, quality assurance, this technical infor‐
mation can be read out from the event and
fault memories by the service personnel, in‐
