Mercedes-Benz S-Class 2006 Problems

No, it doesn’t.

Unfortunately all brands are subject to failures, even Mercedes-Benz, and while you should rightly expect better service from an expensive brand like Mercedes-Benz your car is seven years old. Problems with the air suspension on the S-class are not unusual. You could press your case for some form of compensation from Mercedes-Benz itself, not the dealer, and the company might come to the party for part of your costs. If that doesn't happen and you are left to repair the car at your own cost go to an independent mechanic who specializes in Mercedes-Benz and have them repair it. That way you should be able to make a substantial saving on the cost of the  repair. Many owners have their cars converted to regular suspension, which can be done for much less than repairing the air suspension.
