I have a 96 A6 and the digital display on the climate control unit that shows the temerature has missing pixals that are part of the temp number. Its hard to explain, but the displays only show part of a 0, 2, 3 or anything else except for a 1 or 7. Has anyone seen this and found a fix? If it is a loose connection I would attempt to fix it but if it requires a rebuild of the unit, I could live with it since the unit works fine as it is.
