I raised my car with my jack and had it up for 3 hours. I go outside the next day and see the back of my car low. I check it out and find one of the air suspensions blown. Anyone know what could have caused the problem? Any help would be greatly appreciated. Thanks

I thought I had read in the dinghy guide that this model was flat towable but only the first year that Mercedes-Benz introduced this car.
