I plan to purchase a A4 b6, ideally an 1.8 S line or maybe a 130 sport diesel. It was my desire to have the Automatic/Sequential Transmissions. However, I have since discovered that the Audi Multitronic box have well know issues which can be expensive to repair. Is this so throughout the entire A4 b6 range or is there a year when Audi rectified the issue ? Are there any know Issues with the Tiptronic or the Manual gearboxes ? I assume that Tiptronic and Multitronic both offer the option of a full automatic or a driver input +/- gear change option ? Is a Tiptronic or Multitronic gearbox referred to as a DSG ? I'm aware the Tiptronic box has a torque converter and the Multitronic is CVT system. How can I tell the different between the Tiptronic and Multitronic gearbox from inside the car or by sight ?
