For filling up the system you will use 0-0 liters of special Blue coolant type. In other way 2012 Q7 won’t be used quite long and efficiently. You may use code of motor CCFA and volume figure of 4.2 or just tell the 2011 year of production to buy liquid. For Audi Q7 it’s important to have optimal antifreeze inside. Make sure you service system at Audi with installed 3.0 engine correctly.
So, don’t choose different from Blue coolant and obey the number of 0-0 liters. A lot of BHK motors are used long in Audi cars but only with good service. Providing you keep the rules 3.0 motor installed in Q7 of 2012 year will be long lasting. Look at Audi’s requirements and make your 2010 Q7 serve longer and with no problem.
