OBD connector
142n
The data link connector for onboard
diagnostics is located on the left-hand
side of the driver's side, on the under-
side of the instrument panel and under
a cover panel. The cover has the letters
"OBD" on it.
The purpose of the OBD system is to
assure proper emission control system
operation for the vehicle's lifetime by
monitoring emission-related compo-
nents and systems for deterioration and
malfunction.
An illuminated indicator informs
you of the need for service, not
that you need to stop the
vehicle. Your system should be
checked, however, at the earliest
possible opportunity.
If the indicator blinks or flashes, this
indicates a high level of engine misfire.
Reduce speed and contact your
nearest BMW center immediately.
Severe engine misfiring over even a
short period of time can seriously
damage emission control system
components, especially the catalytic
converter.

lamp for Canadian models.
If the fuel filler cap is not on tight
enough, the OBD system can
detect leaking vapor and the indicator
will light up.
If the fuel filler cap is then tightened,
the indicator will usually go out after a
short period of
time.<
