I have a 2005 s4. It is one month old and it has been in the shop 3 times for this same code. Last time they said some coolant pump was not turn on by the computer, they said they switched it on and everything is fine. Now the light is back on again. The battery was disconnected over the weekend to install an amp and sub, would that cancel out whatever they did to the car? Or any ideas on what is causing this?
Thanks
