VAG-COM: Hobby or Pro? Which Version?

Hello,

I would like to order a VAG-COM device, but which version should I get?

Hobby or professional.

Existing vehicles:

VW Caddy TDI, 66 kW (AHU)
Audi A4 2.6

The Caddy will be replaced by a Touran 2.0 TDI next year.

Regards,
Bernd.

It seems that with the Touran replacement, you'll likely be forced to use the CAN-KKL Pro adapter, as all communication in that car will now only be possible through CAN bus monitoring.
