how do you replace the thermostat on Audi A-6 year 1998 model quadro. 2.8 cilinders
No..
If this is a 2.8 V6 the thermostat is located on the front of the engine. Ask 'Where is the thermostat located on a 1995 Audi A6?' on this site and you'll find someone has done a great job of explaining how to find and replace the thermostat.
The thermostat is electronically controlled, and if faulty will set off the cel. it is located on the drivers side of the engine block, directly beneath the intake manifold.
You have to take off the front end of the engine, as if you were replacing the timing belt and water pump, huge effort for a thermostat.
