No, noticed the sound is more pronounced if I push the car hard from lower gears but then disappears on higher gears. Could be the fuel pump but fuel pressure looks normal on the scanner. Might change the fuel pump next month just to see if that was the culprit , else the car drives fine and can't complain about it.
@@GigiBeleaDK Hello! So solve this problem? Have an similar: ua-cam.com/users/shortshRZrW5vdUkY?feature=share ua-cam.com/users/shortsJyMKCQ4dUNY?feature=share
@@andriizimich Still , sound does not seem to come from engine , it is some other thing I believe. Changed chains , manifolds (both) , water pump etc on mine. I see yours is high mileage as mine... only thing I did not tried was to drive without AUX belt on , this would eliminate the AC kompressor and Alternator.
@@andriizimich Only thing I did not tested was the high pressure pump ... noise can come maybe from there.. will try to have a friend over and try to check if noise might come from the pump.
Same noise on my n57, in a F10 :/
Mine only does this when it's cold for the first 4 or 5 minutes, once at 90c to 100c its gone? Was this similar for you.
Mine does the same, did you find out what it is?
Still driving daily.
@@germanbmw1001 nope , still driving daily.
@@germanbmw1001 timing chain, very slack at 103k miles.
Did you discover the problem was it a injector?

@@GigiBeleaDK find out the problem guys? I have m57 330d same noise from 2k rpm to 3k rpm under load it’s more louder that trrrtrtrrr
Resolved ?
No, might be normal wear and tear. 15000km later same sound. Checked 2 more N57D30 and they also sound similar.
@@GigiBeleaDK its Rod bearing shell for me, with the same noise...
@@Ao33et38 If it was rod bearing it would have said BOOM after 20.000km :) It's not a knock , it sounds like missfire.
@@GigiBeleaDK injectors ?
@@Ao33et38 Changed all 6 with factory exchange units.
