Help engine noise
Hi I got a 2003 m3 with 17,000 miles when I rev the motor to about 3,000 rpm it has a tapping noise did these motors have any major problems? somebody said there was a recall on the bottom end? do they have problems in the bottom end or i thought it could be a vano failure do the vanos make a noticeable noise if there going bad?
