I'm getting a muted clunking / knocking noise on rougher roads. It's there on speed bumps, but not really so noticable. It happens more on just rough bumpy road than anything. I'm on Cupra bushes. That's the first thing I did when I got the car... about a year a go. Maybe they're worn already?! I've just recently changed the "dog bone" and gear box engine mounts. This seemed to lessen it a bit and it's more of a muted clunking now. It does seem to have eliminated a clunking I got whilst rollin
