2006 A3 3.2L V6 Thermostat Replacement P2181 Engine Code
I have a 2006 Audi A3 3.2L V6 with a check engine light and code of P2181, which is defined as cooling system performance error: Check ECT Sensor, thermostat, and water pump. The dealer recommended changing both ECT sensors first. I replaced both of the ECT sensors and the check engine light /code is back on. I believe the problem is an intermittent thermostat.
Anyone have the replacement procedure for the thermostat or other suggestions for this engine code? A location of the thermostat would also be a huge help.
Thanks!

I know this is an old thread, so the problem may be fixed by now. what was the final diagnosis?
