Hi

We have just Purchased a ELM OBD2 car diagnostic Scanner For Our Audi A4 2004 1.9 (54) reg. We are using Car Scanner ELM OBD2 app upon setup which connection profile should I select.

Do I chose one of the following

1. OBD-II /EOBD All OBD-II compatible Audi Vechicles

or which one should I select

many thanks

Matt
