Hello!,I'm own A7 bitdi 3.0 313 hp model,I have issue and unfortunately from 6 months I can't repair it.Car issue is engine can be both hot or cold doesn't matter between 1000-1400 rpm during cruising car is juddering like a misfire.I bring car to service they put in diagnostic there is no fault on diagnostic service told that issue can to be from EGR,inlet manifold.First they removed intake hose and sprayed Egr&manifold cleaner spray during car was on 2000 rpm and then they removed egr,and inlet manifold they cleaned and changed seals of egr.So after almost issue fixed it was again juddering and misfire on low rpm during cruising but was more better not was like before misfire so passed 3 weeks I drove car long distance around 1200 km unfortunately on road Truck crashed and stuck on road so That's why traffic locked and I drove car about 1 hour and half with 20 km/h speed and after car again started judder and misfire as like before between 1000-1400 rpm.So is there any body who had same issue ? What was issue? Unfortunately we can't found issue on diagnostic
