hey all I have stored the e55 for about a month now and today i see the car wont start at all, and the rear of the car is sagging down over the tires

1) if i charge the battery to full will the rear struts inflate back to normal or does this mean they are toast and i need to tow the car? before the car was left for a month the struts were fine

2) will the sagging over the tire damage the tire?

thanks all

Time for some new struts! Could also be a leak at the distribution block thingamajigger.

Even weekly suspension sagging is not too much to worry about.
Charge the battery (disconnected from the car) and if the problem still stays after engine start, than worry.

I usually agree with you, but don't here. Sagging = leak.

My E63 will sit for weeks at a time and have zero sag.

It all depends on your definition of leak.
I am old enough to remember tires that had to be inflated every week. It was not consider a leak, but comparing to today's tires that hold the pressure for a year - it should be?
Rubber does allow some air "migration" that is why nitrogen tire fills made big hit few years ago.
So far no nitrogen on air suspension.
