i just recently purchased a 2005 s600 with 23000 miles on it. i have a question about the shocks in the rear. Ok when i turn the car off for a night or evening. then come back out in the morning to get in it to drive. All of the air has been released from the rear right air shock and you can tell when you walk up to the car that the air has escaped. Is there something wrong with it or should I not worry myself. As soon as i put the car in drive and move maybe an inch or two. It quickly raises back to its proper height and is ok until the next time i leave it off for the night. Is this an early sign of it going bad.

Please Help
