Low Vehicle Ride Height Due to Leaking Rear Air Springs on Mercedes-Benz CLS550

Problem Description and Possible Solution

Rear air springs (bellows) may develop leaks, which causes the air pump to run more often to maintain ride height. Our technicians recommend that leaking air springs be replaced.

My driver side front air system is leaking some type of fluid hydraulic I assume and when I press the airmatics button it takes forever to raise..going to Mercedes to find what's wrong
Car kept reporting low tire pressure adn looked lopsided when not running. The pump would turn on everytime i opened the car door, but would only lift the car so much. While drivving the red light would flash and say the vehicle height is too low. The Benz dealership reccommened a new driver's side air strut costing $1200 just for the part sans labor! Took it to another mechanic and was told the only way to buy the part was from the dealer because of the model year, and that the air suspension is a common problem. He even had one customer who decided to remove it altogether and replace with regular struts (a 5 hr job). Unfortunately i have found no kit like that for my model year, so I guess Im forced to get it fixed and risk the other side breaking in the near future. I guess more money, more problems!
mine is the same issue, but with the front right shock. The pump runs more often then it should to keep it pumped up. If it sits for more than an hour, the right front dips and covers the top of the tire. When I open the door, the compressor pump comes on and lifts the right front to the proper height. I assume it happens while I am driving as well. Having it serviced today, initial comment from mechanic is the shock needs to be replaced.
It takes about 8 hours for my cls550 rear suspension to lower. But once I turn the car on, it raises up in a 1 or 2. I have read about the air springs and I think my airmatic has a slow leak

Service engine light comes on.
Took it to mechanic - timing chain/belt needs to be repaired/replaced $ (6,000.00)
Any suggestions.
Front struts had to be replaced. One failed a year ago and the other just failed.
Car has 33,000 miles and is almost 6 yrs old. Wondering if I should just replace the rears before I get stranded on the road.
At work, came out saw a car leaning on drivers side (to a point it covers the tire) and i started it didn't raised up much but droves it home and parked it (left it on jack) called mech said needs replacing both front struts approx $1850 (could be more, remember, this is the conversation over the phone and they haven't looked at the car and the parts are after market... aauugghh!)
I need some serious good luck....
Noticed the car was sitting uneven in the garage. Took it for service and they replaced the air bags 3 times before replacing the entire system just to get it home and it looks exactly the same as it did to begin with. I'm starting to question if the dealership replaced anything.
Mine lowers all the way down. Turn on the key and the car rises. I replaced motor a while back and one of the struts also. It looks awesome dropped down. LOL
