I bought this Audi a4 quattro 5 speed turbo, its a very clean car inside out, I would say 9 out of 10. Runs great strong engine, nice steady when at idle, problem is it did not pass emmissions. Its says HIGH HC readings, HIGH CO readinds, HIGH NOx readings. No diagnostic trouble codes. What can it be?
