General
This repair group covers airbag
components. Airbag system repair and
fault diagnosis is not covered here.
Diagnostics, component testing, and
airbag system repair should be carried
out by trained BMW service
technicians.
Note:
Airbags are also known as the
Supplemental Restraint System
(SRS). In the E46 cars the
occupant safety system is called
the Multiple Restraint System
(MRS).
Special test equipment is required
to retrieve airbag fault codes,
diagnose system faults, and
reset/turn off the airbag indicator
light. The indicator light will remain
on until any problem has been
corrected and the fault memory
has been cleared.
Individual airbag system components
can only be tested electronically when
installed in the car. BMW service
testers DIS or MoDiC or equivalent
must be used for diagnostic work.
Special tools
Most airbag system repairs can be
performed with normal shop tools. Use
BMW special tool 00 9 321 or
equivalent plastic prying tool to pry out
plastic interior parts without damage or
marring.
