Ran fault codes, found ect sensor @ 48c degrees, replaced, Installed new sensor in water neck flange at radiator, problem in instrument cluster, no repair attempted. AC head control unit had internal short circuit, shorting out the comfort system. Instrument cluster was having catastrophic communication problems. Faulty AC control head unit and instrument cluster were replaced and re-coded. "Econ" button was stuck on...no heat, no air-cond. just outside air coming through the vent. system. New instrument cluster needed to be re-programmed. I am taking the car back to the original shop to take care of the ongoing check engine light and the abs system randomly coming on, I anticipate the repair being done this month (Dec.) 
89000 mi Trip was to work on check engine light, abs brake light and traction light from previous trip, ec sensor was changed for the third time, to no avail, as soon as warning lights are cleared, they reappear.  Also, crimped wires from the trunk lid wiring harness are giving false brake light out warning lights....The Audi wiring harness is roughly $4200 for the part alone, so it will either be spliced to fix, or I will learn to live with it if I keep the car.
