OP6 27 Report post Posted June 28, 2010 My m20b25 makes a strange droning noise. follows the engine note but doesn't really get any louder. it's a mystery and i've come to the conclusion if you're old you can't hear it. as my dad and boss can't.

f.g. 0 Report post Posted July 5, 2010 Hello, does it happened when it's hot or cold, in a certain gear? when did it start, did you do any changes or anything since or before the noise started? Quote Share this post Link to post Share on other sites
