True, there is about 10mm to be trimmed inside the heater box from the divider plate that separates the two zones. It doesn't need to be a neat cut, as I don't really care about maintaining two different temperatures.

Less than $100 I think for the Audi A6 (late 90's model) heater call if I recall correctly, when I did mine.
