OBD interface socket

The interface socket for onboard diag-
nostics is located on the left-hand side
of the driver's side, on the underside of
the instrument panel and under a cover
panel. The cover has the letters OBD on
it.

This interface makes it possible to
access data on emissions-related
components using special equipment.

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
opportunity.

If the indicator blinks or flashes, this
indicates a high level of engine misfire.
Reduce speed and contact the 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.

SERVICE ENGINE SOON

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.
