hi all! I have an audi 2010 a3 8p black edition 1.8TFSI petrol around 70k milage. Been running a dream since i got it at 30k, regular services no major work However - it RUNS through oil. Id say 5L every 2-3 months. Ive coped but enough is enough. Also - when idle and rev the car - puffs of black smoke come out as well as white!! Warning signs?? When idle slight vibration/hesitation but no drops in revs. Coolant is the same level No error codes as of yet Any help would be hugely appreciated!!!
