Left- dust cap on. Right- dust cap removed.

1987 Through 2000 (Located under the hood)*

Important Note: Mid-2000-on often use OBD connector, page 4

BMWs’ built 1987 to year 2000

have a 20 pin diagnostic connec-

tor located in the engine com-

partment. The car image at right

gives a general idea of where the

connector can be found depend-

ing on year and model. The im-

ages below show what the con-

nector looks like, covered and

uncovered.

Orientation:

BMW located the 20 pin diagnostic connector in several locations in

varying orientations. You may find that when the tool is plugged in

properly, the face panel is actually upside-down relative to your

position.

Plugging tool in properly:

When inserting the R5/FCX, plug it straight in, as you would plug a

lamp into a wall socket. The car’s connector appears to be a twist-on

type, but the R5/FCX DOES NOT twist in (twisting will damage tool

*Not there?

All BMWs 1989 - 1999 have the above connector - no exceptions. Mid

2000 forward is when BMW began to phase out the above connector

in favor of the “OBD” connector on page 4.

LOCATING THE DIAGNOSTIC CONNECTOR

Under the dashboard:

R5/FCX FACE PANEL

2001 and Later (Connector Located inside the Car)

Important: an adaptor may be required on some R5/FCX

configurations see Appendix, page 39 for details.

To locate the Diagnostic Connector in most BMWs built 2001 and

later, open the driver’s door, kneel down and look up at the underside

of the dashboard. You will see the

diagnostic connector near the pedals,

above the driver’s left leg (see

illustration below.) You will see a

rectangular access panel, (often

embossed with the letters OBD) with a

rounded thumb grip you will use to

snap it off. The cover will swing

downward revealing the 16 pin

diagnostic connector inside.

Not there?

Try looking on the passenger side of the center console, or to the left

of the drivers left leg. Note: A small number of 2001 and later models

also have the 20 pin connector, such as the 2001 X5 and the Z3 up to

2003. See pg 3.
