i heard this wierd sound from my transmission or mayb drive train. see if u get the sound as well.
put the car in 1st gear and go down a slope. u dont accelerate, and dont engage clutch. when the RPM is somewhere between 1000 to 2000 u will hear a "scary" rattling noise.
i did some google search and found this link. to summarise the link - they say it is ok and NOT a problem. http://www.bimmerfest.com/forums/archive/i...hp/t-61363.html
just wanted this forums views. thanks.
