dunno

my problem is airmatic stop car too low

i have a s350 from 2004 and i have a guestion.

Is it possible to replace an airmatic suspension by a normal suspension?
If it is possible are there any suggestions about which one?

possibly faulty airmatic pump for suspension, first open boot and boot floor mat then have look on spare wheel, you can see your tools extra fuses and fuse diagram on it, take fuse diagram and read it you can find what's the fuse no and fuse box where is the airmatic pump fuse and relay is, check fuse and relay first, if the fuse blown replace same fuse for that now you know where are the extra fuses, get one from that, start engine is the car not rise up operate the switch above the radio still not working either faulty airmatic pump or control unit, you can check pump yourself turn steering fully left, remove clips from bulkhead inside wheel arch only need to remove front section then have a good look inside you can see airmatic pump is hanging on chassis rail under the right head light, have a good look wires on pump if it dried and broken that's the fault, only solution either repair pump or replace new pump. if not the faulty pump you have to get diagnose the car by experience technician, is this information helped you?

check the relay for the airmatic compressor it is on the passenger side in the engine compartment right next to the hood hinge. pull the cover off and its the 3rd relay back from the front. the relay might be sticking closed but have it checked before it causes the compressor to burn itself out

The suspension has a leak somewhere and/or the airmatic compressor has stopped working properly. You need either the Mercedes star diagnosis system (SDS) in order to access the suspension control module to tell it to raise the vehilce or you can try to trick it by jacking up the car so it thinks it's sitting at the correct ride height. But as long as the display reads a warning it won''t allow the airmatic compressor to run.

souds like air bags in ridding systen have a leak

Sounds like you may have a leak in the airmatic suspension struts on the rear. These govern the height of the car in different modes. Not an immediate problem unless you are loosing a visible amount of fluid but it will only get worse.

To check if you have airmatic you will have buttons just behind the gear lever which can be used to put the car in to a stiffer, lower mode or to raise it for rough ground
