According to the Audi website, an approved used Audi has to pass over 100 checks. When I bought mine in May this year I got a form with 70 checks that had allegedly been carried out on the vehicle. At the top of the form it says 'stage 1'. Is there another form for the other 30+ checks that should've been carried out? Should there be a stage 2 sheet? Thanks for any help on this.
