Like, seriously, a slight feathering of the brake pedal will make the front go all wonky.

Vacuum lines are "air tight" though - vacuum is fine, and mounts seem nice and firm - not leaking - and if I use a prybar to try and wiggle the engine, they don't seem broken.
You can't test properly vacuum controlled engine mounts with a prybar.
On 3.0d these are good for about 120-150x km. On high speeds vacuum control avoid a lot of pressure and vibration on the front axel
Wrong torsion and angle of the engine on high speeds is more than enough to screw up your steering road stability
Take a look at the electrical valve which was revised already 3 times by bmw.
