I've noticed that after letting my 08 e550 sit for a week or so, both of my rear bags are deflating equally. What would cause both to deflate?

Old age, when the bags go out on Mercedes, they typically go out within weeks of each other, you're lucky and they're going out together. Easy fix and the indy's can get the parts and have you out the door for around $2k, if not a little less.

Not sure how different the rear air springs are on your car vs mine, 2009 e350 wagon, but I just replaced both of mine. Cost me ~$650 for the parts and about 2 hours each side (actually 1st side took longer as I learned ). Not a hard job and I'm a newbie. Here's the thread, maybe it'll help.
