ignition lights on 1996 Audi A6 Quattro
is all this happening with the car off and key removed? given the type of car, my first choise is an ignition switch even though this is unusual as a symptom. have you had any installations done recently like radio wiring that may have been crossed? to check, remove the inst cluster and unplug the switch (2 screws hold the lower trim under cluster, then 3 more to pull it out). unfortunately when the cluster is removed the outside temp and gear display bulbs usually burn out.
