I recently ordered an A4 Avant S-line 2.0 TDi Ultra 190PS. Called the dealer yesterday to change the order to have the S-Tronic gearbox instead of the manual that I had previouly ordered. The sales person I have been dealing with said that a new order form had to be submitted and that the Ultra was now unavailable for the S-line but still available for the Sport. They guessed that it may be due to the fact that all new chassis were to be made from the lighter materials which previously qualified them as Ultra so there is now point in the differentiation. Can anyone shed any light on this?
