Your car probably doesnt have a OBD2 port, instead it will have 3 x 3 pin connectors, each serves a different purpose. Their probable locations are:
Air-bag control unit = Under the passengers glove box.
Brake servo unit = Next to the brake reservoir
ECU = Behind the inlet manifold under a plastic cover, mounted to the firewall
Each plug will be sheafed inside a plastic cover. Simply take the plug out of the cover to use it.
To connect to the ECU/air-bag control unit, you'll need to do the following:
1) Get a laptop
2) Install multi-ecu-scan (
https://www.multiecuscan.net/)
3) Buy a 3 pin to OBD2 connector
4) Buy a VAG KKL
Multiecuscan adaptor
Then plug the 3 pin into the connector, the VAG KKL adapter to the OBD2 connector and VAG KKL adapter connect it to the battery.
When connecting to the air-bag unit I used jumper cables to connect the VAG KKL adapter to the battery.
