CAR TOO LOW TO DRIVE

sounds like the seals on your airmatic shocks have broken, which they do over time. You need to have these repaired by a certified M-B shop. The pumps, there are two, that control the suspension may have gone as well. This is a very expensive repair with the pumps. There is an alternative, search the web for the conversion kit to standard shocks. Maybe some one can chime in on these, as I have zero experience with them.

Most likely a strut failed (leak). The airmatic struts are $1300 from Mercedes and about 4-5 hours labor. So you're looking at $1700 plus tax. I just replaced my both front struts. One failed, had replaced. Then 3 weeks later, the other failed. Since then, I've discovered you can buy rebuilt struts from Arnott Industries for $399 (+ $100 core charge). You can also find Bilsteins for $795. Of course, this means you do the work yourself (never done this myself), or you find an independent shop willing to do so.

My car did this one time on a trip 500 miles from home after driving it all day in heavy rain. rented another car and let it sit over the weekend. Came back and it raised up again, drove it back home, no problems EVER again (almost 2 years ago). Took it to Mercedes, they told me I had an autozone battery and I still do. I sure don't take it to Mercedes anymore. I think they let the carwash boy work on it that time. So its never happened again. I thought it was the airmatic pump (failure) but no. Just a fluke. Not very encouraging. Had the car since showroom new. No rough treatment ever just a non mercedes battery. It shows that the MB Dealers can't even fix their own cars.

I had the same problem. The dealer replaced the airmatic pressure pump.
