C30 judders

My wife has a 2011 C30R auto trans. There is a juddering when going from idle into gear. It lessens when driving. I am trying to diagnose this. My thoughts are loose engine mount or vacuum leak. It runs well at high speed and the idle does not change much when the oil filler cap is removed. The engine mount by the coolant reservoir appears solid and not leaking. How can I check the other mounts or do I have to take them off for inspection per the article on this site? The tapered air intake to the left of the hood latch appears to be not sealed well to the down pipe. Would this cause a vacuum leak?
Thanks for any advice
