Hi Guys,
I'm writing to you looking for some comments and thoughts from your side, as I've noticed really strange sound, kind of metallic type one, after injectors were replaced by dealership as part of service action covered by one of SIBs.
Before those injectors got replaced engine sounded really smooth and currently it sounds not nice even as for a diesel one.
Video with the sound is available at:
What do you think?
Knowing authorized BMW service they might try to say that's normal and it does not sound normal to me as it started to be like this only straight after injectors were replaced.
BMW might try to say also that the problem is with something else and injectors replacement only made it visible... is it possible?
Thanks in advance!
