On E65,E6X,E70 mounts are switched to hard when vacuum is applied.
On E46,E53,E83,E9X mounts are switched to soft when vacuum is applied.
It means mounts are in soft mode when there is no vacuum at idle.
So do one test.Unplug your vacuum hose from the mount and rev the engine past 1000~1500 rpm and check if vacuum is applied to the mounts.If it is ,means your pressure converter solenoid valve is working correctly and your system is working properly.
Hope it will help you... |
DUDE! That is amazingly helpful! I have been racking my brain wondering why there was no vac at idle! This answers that question. So my mounts are soft with no vac, and hard with vac? This would explain why my idle seems slightly worse when I bypass the solenoid and connect the mounts to a source of always on vacuum.
So next question, how did you resolve your issue? I read your thread but I didn't see a resolution?
