    I have audi q5 3.2 liter gasoline year 2010. I got this faultcode P0491 and P0492. Now i have already changed the valves and tubes but still get this faultcode. What could be the problem more? Is it something i have missed to check? Some people say the ecr could be faulty, it is a common problem. Is that so?
