[Vatountas]

Good evening, I have a bmw f20 116d with the 2.0d and yesterday I noticed a small oil leak from the lower turbo screw on the intake side. is there a chance that it is leaking from the o-rings and if so is there a spare part or will the turbo need repair? The car has 105 thousand kilometers and there is no difference in its performance. It loses about 4-5 drops per 500km
