My s500 developed a problem on the right front side. I took it to a certified Mercedes mechanic and he diagnosed the problem as the air compressor. I had him install the air compressor. It appeared to be fine and lasted about 20 minutes after leaving and the same problem started again. I have cranked the car and allowed pressure to build on the active ride system and when it id charged I can not hear any leaks. However when I cut the car off and the vehicle is at proper height and will lay down in the front right after a short period of time. Any suggestions or help would be appreciated.

TYPICALLY this could be because the air bags are leaking and caused your compressor to overwork itself to death. The airbags are not designed to withstand temperatures below 40 degrees and above 94 degrees. Can you believe that!?!? Dry rot starts forming on the inside fold of the bag making it very difficult to detect with the soapy water test. Anyways.. i went through all these problems and several hundred dollars before I finally decided to convert to a passive coil spring system. I got it from Strutmasters.com with a lifetime warranty. http://www.strutmasters.com/mercedes-s-500-suspension-s/112.htm I have been riding on them for about 8 months now and am very pleased so far! I actually now PREFER the coil spring ride to the air ride and was surprised at just how comfortable the ride was. Hopefully you won't have to go through as much money and heartache as I did before I went for a more permanent solution. By the way, my shop only charged me an hour per wheel to install the kit so it was pretty cheap on labor too!!!!

Hi there
First of all may i say i feel your pain. literally. the same thing happened to mine. here is what i did
Firstly i needed into a locked boot urgently (for wifes wheelchair)
so i cut a rectangle out of the boot put my hand in and pulled the release mechanism, that worked but left me with a hole in my boot.
I suggest that you try this instead.
remove back seat
the central locking pump is located next to the battery (black box with yellow air lines going into it.)
Unplugg the filler cap cover air line, then unplugg the boot air line and put it into the filler cap cover socket.
now when you unlock the car the boot should automatically open.
If it does not the problem it on the boot air line and you should strip the trim out of the boot to check, but you still have to get in and may have to do what i did initially.
If changing the air line worked then you will soon get tired of having to shut the boot everytime i solved this problem by routing the filler cap air line to a pnuematic switch (LEGO) This switches between the boot and the filler cap. bit naff but it works and cheaper than having to replace pump and have computer and keys re-coded total cost around £600.
op that helps

I think that this might help you. The a/c compressor is a continuos running type there is no clutch. It has a wobble plate internally wich changes the piston stroke. Screw the genises machine-it is probably only reading a partial on the climate control module. see if you can find the self diagnoses diagram either from the factory or if you have all data. you can pull the codes right from the unit itself and they will be accurate. If you can,t pull codes see if you can get an actual value of the sensors in the a/c unit. You should be able to pull that up as well if not try the genisis. Look very closely at you evaporater sensers(left and right) you will probably see a -40 degrees-that is the sensor default input reading when the sensor goes open. That sensor is used to moniter the wobble plate position of the compressor.

You must go to the dealer workshop for replace shock in your car, after replaced shock in your car must need to re calibrate the airmatic suspension through Mercedes diagnostic CPU otherwise It won't be working properly,
