Actually, from what I have heard from a couple dealers, the nut that attaches the EGR pipe to the bottom of the EGR base coming loose is somewhat common among the VX. The nut loosens over time and either sits there or slides down the pipe a little bit, severing the connection between the EGR valve and the pipe. The leak is loud when accelerating, but I didn't notice much, if any, power failure.

I have, myself, had the nut loosen a couple times. I'm not saying that this is the problem Coach is having... in fact, he should have his engine looked at ASAP to diagnose the problem!
