Socket for On-Board

Diagnosis OBD

Primary components that make up exhaust

emissions can be checked by a device via the

OBD socket.

This socket is located on the driver's side to the

left, on the bottom of the instrument panel

underneath a cover.

Exhaust emission values

The warning lamps come on. The

exhaust emission values have wors-

ened. Have the car checked as soon

as possible.

Canadian models display these warn-

ing lamps.

The lamps flash under certain conditions. This

indicates excessive misfiring in the engine. If

this happens, you should reduce your speed

and visit your nearest BMW center as soon as

possible. Severe engine misfiring can quickly

lead to serious damage of emissions-related

components, especially the catalytic converter.

Event data recorders

Your vehicle may be equipped with one or sev-

eral measuring or diagnostic modules or a

device for recording or sending certain vehicle

data or information. In addition, if you have

signed a service contract for BMW Assist, cer-

tain vehicle data may be transmitted or

recorded in order to facilitate the corresponding

services.

Care

Important information on the care and mainte-

nance of your BMW is contained in the Caring

for your vehicle brochure.
