hi aleykum brothers my car 1.4 hdi bipper 266000 km is going to happen for a short time 6 7 master, they said there was no problem in the engine, but it seems to me that there is a blow, the sound that comes when I do the bidet cover is like the sound of the bed hit, but there is no sound when the lid is closed, the performance of the car is impossibly good. no condition, no sound in the turbo, no exhaust fumes, what do you think is there is smoke like leaking from this blower and sound oil cubes, I think it is normal, thank you already
