I was lucky to be allowed to work immediately, very soon after I started then, on the Quattro Spyder Showcar in 1991 for the Frankfurt Motor Show and this was a great experience. Afterwards I did a lot of production work in Ingolstadt, the headquarters studio of Audi, but then I was also allowed to go to the little tiny Munich design studio were we developed work for Volkswagen and Audi and, in parallel, we built up a group design studio in Barcelona at that time for Audi, Volkswagen, and SEAT.
Then I moved there with my family, near the studio, to live in Barcelona for almost three years, doing work for Audi, Seat, and Volkswagen. Then after this experience, I was sent by Audi to lead the Munich studio, head the Munich studio and we did showcars for the A2 and also production for the A2 at that time in1997. In Frankfurt and in Tokyo we showed these concept cars to introduce the car and then also the production A2.
After this quite short experience in Munich I was asked to come back to Ingolstadt to be head of the interior design team. This lasted until 2002, I was doing all the production process for all the Audi interiors at that time.
