My car is Toyota Auris ,Diesel, Model 2012 with 85000 Km. Recently when I try to speed up i, the car takes longer to speed up. It’s like the turbo gets a delay taking orders from the engine. But when I reach more than 60 Km/h, the turbo works and thje car works normally. I have changed all the filters in the engine in vain. I have ran a diagnostic but it does not say anything. Some say it might be the injections but I doubt it. I have added some dirt purifiers in the tank but it does not seem to work :(. Thanks for advising me
