VW GOLF 4 obd conector pinout

[zuranic2]

Hello everyone.

I have '04 Golf 4 1.6 16V Ocean.

OBD conector have occupied pins 1, 4, 5, 6, 7, 13, 14, 16.

I found in Elsa that is:

1 and 16 - 12V

4 and 5 - ground

6 - CAN High

7 - K line

14 - CAN Low

I'm wondering what pin 13 is used for? No explanation in Elsa.

Is it programming line (like in BMW 20-pin conector)?

Thanks

Hello, I also think that is direct access to ECU. Only, this is BCB engine code.
