Hi, i went to purchase a 520d 2008 m sport auto today however took a mate whose a mechanic and he did all his checks then on a test drive we noticed while driving and idle there was a vibrating noise so under the hood the engine is visably vibrating but the Rev counter looked fine, underneath looked fine, everything he could see and check looked good. The rev counter was steady.

I’ve read online this could be the injectors or even something such as a loose bolt or something. Any thoughts?

I didn’t purchase the car yet they are going to check it out and hopefully fix it but my friend was happy with everything else, all perfect apart from this one issue so I’m hoping it’s an easy fix.

Any thoughts appreciated. Thanks
