1996 A6 climate control.
I have a list of codes and DTCs with instructions on how to access the DTCs on the Climate Control.
On the list of codes the numbered list 1 is for the DTCs, when using this (01 c) only one DTC shows.
Does anyone know how to show more than one DTC?

The routine is IG key to first position, press and hold the RECIRC button press the up arrow button to enter the DTC and 01c shows on the lh window on the CC head.
Then press the RECIRC button again and a DTC shows or 000 which = no DTCs.

On the list from 2 onwards the actual temperature or actuator/potentiometer reading shows.

IG key to first position, press and hold the RECIRC button press the up arrow = 01c in the lh window.
Press the + button on the temp' lh window to show 2, press the RECIRC button to show the actual reading.
Press the + button on the temp' lh window to show 3, press the RECIRC button to show the actual reading.
