The the 2004 A8L with 64,500 suddenly overheated. I drove it home (about 3-4 miles) quickly and will bring it in or have it towed in for service tomorrow.

Check engine light. Codes said failing thermostat. $871 to fix. Recommended same time do the timing belt, serpentine belt, and water pump with the thermostat, quote, $2065.

Check Engine light on...told by local mechanic that thermostat is stuck open (or so I'm told)...also told it's very expensive to fix, since the whole front end needs to come off to get to it...no fix done.
I had my Audi A8 Quattro 4.2L Parked in my heated garage for 6 weeks i drove it out and after about 15 miles it started running above normal temperature i had to turn the interior heater on to maximum to get the temp back to normal my audi main agent said i needed a new water pump and thermostat at a cost of £1675.53 i was not happy this obviously must be a manufacturers design fault i mean you would not think a £57000 car would need a water pump and thermostat after a mere 26000 mile and it is not soughted yet as i think Audi should rectify the problem or at least meet part of the cost.
my a8 qquatro overheats but does'nt read it on the gage. i had a new waterpump installed> it leaks a little somwhere on the left when parked and turned off and the cooling fas don't continue to cool it when turned off. don"
't know what to do please help.
