Default EGR Valve Replacement on 300 Touring 3.5L

Getting a P0406 code ("EGR valve - high voltage") on engine light. Has anyone been successful in replacing the EGR valve on a 300 Touring 3.5L engine without removing the intake manifold cover? How about from underneath the car and reaching up? I can't even see the valve from the top because of the over-sized intake, let alone trying to get my hand in to remove it!

Perfect. I appreciate the option--I'd rather remove from underneath than to have to remove the intake manifold! At this point, the P0406 check engine code hasn't reappeared for a few weeks, and I've heard from some shops that some of the throwing of codes is not because the valve is necessarily defective, but sometimes it is related to a calibration problem with the sensitivity of the sensor and/or electronic control module. What do you think?

Rather than posting a new thread, this one looked like a good place to ask the question again...

2005 3.5L RWD. Getting code P0404, appears the answer to replace EGR assembly.

I have the service manual, which says to remove the upper intake manifold, which I would rather NOT do! Car has 40K, don't really want to disturb it if possible.

If i want to change the EGR valve without removing the upper intake, how difficult is the job, and how about how long will it take? I have decent tools and mechanical aptitude.

Thanks in advance for any help!
