Up for sale is a Genuine Audi thermostat and water pump assembly.  Purchased the water pump and thermostat for a 2018 Q5, put them together but never installed (coolant leak was from the connecting hose).  No longer have the original packaging so could not return.  This should fit several different newer 2.0t engines (A4, A5, Q7 etc) from Audi, but not all as there are a few different variations of the thermostat depending on engine code.  Please be sure to cross reference the part number as seen on the thermostat to ensure compatibility for your application.  The part in the picture is the one you will receive (including union).  All Sales Final!!
