2001 A4 2.0 (B6) - what do I need ?

[AvantSE]

Would be grateful if someone could tell me what I need for the above car, to read fault codes and activate/deactivate various features?

And if someone could tell me where the port is situated on the car, I would be even more grateful !!

Thanks,
Chris

Assuming an official Ross-tech lead

For your A4, just choose whether you want USB or serial port.

Ie
KEY-USB or
KEY-COM (consider that serial ports are becoming less common, so USB the better choice)

If you are likely to change to a newer Audi/VW in future consider one of the leads with Canbus capabilities. (also backwards compatible)

HEX-USB+CAN Interface
HEX-COM+CAN Interface

All of these official leads will fully unlock all features of the software.


There are third pary lead available, but will limit functionality somewhat, and or limit you to certain old versions of the software, and require you to buy the registered version of vagcom if you want full function, as the free shareware version is limited in its operation.

You can buy vagcom direct from US, or through
SK Pang www.skpang.co.uk a poster here who sells both official leads/ software and compatible third party leads


Your diagnostic port should be under the dash on the drivers side iirc. Look down in footwell area, then back up at the dash to where it goes back to the bulk head.
