You more than likely have a serious pressure air leak in the system. More than likely one or more airbags.

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,

Sorry but iam a bit thick this end ,now what are you playing with to stop this pump from working as you havent stated the full facts ,if its not running right with the air pump not working then leave the fuel cap loose a bit so air can enter the tank that will keep the vehicle running while you explain a bit more as to the problem

By not moving I assume you mean lifting and leveling? The good part is all the mechanisms required to make the pump run are working. The part you are having problems with is containing the air.

There should be a Master "dump" valve to allow the air to escape. Sometimes these solenoids freeze. There are also solenoids for each end or wheel to level the car. You have, of course air lines and suspension bags.

If any of these leak, the compressor can not keep up and will run continuously. You have several options. Depends on whether you can fix it yourself. Using a water spray bottle with soapy water, you can wet each air line and suspension bag while the compressor runs. The soapy water will bubble at the leak.

Or you can have a special scanner plugged into the diagnostic port for the suspension. It can "read" the sensors and indicate what is wrong.
Not all places have this type of machine. The Dealer, any GM brand Dealer, can attach this equipment and evaluate the system.

Some repair shops, body shops, may have bought these special scanners. You would have to call around to avoid going to a Dealer.

Since the system is leaking, you will not have to deal with all the pressure that operates these systems. But they can be dangerous and they do support the weight of the car possibly sliding off jacks if the system drops.

I hope my solution is helpful. You may find the parts aftermarket.

SOURCE: 2000 Lincoln Town Car Signature, replaced the rear air bags, all fuses and relays are good. Passenger side has more air than drivers. How would I release the air in the bag or bags and/or reset the ai

The level sensor may have detached. aIf so, reattach it, go into the trunk and find the on/off switch for the suspension and turn it off for a few minutes, then turn it back on. If it is not detached, you will need someone with a scan tool to manually cycle the raise/lower functions
to restore level condition, while looking at sensor readings to see of they are changing accordingly.

Mercedes After market Shocks Fully inflated

Sounds like you have a case of "stuck shocks". There is such thing and they have to either be driven over a speed bump or something similar to see if they will come down. I'm sure they are riding very "stiff" and uncomfortable. If that doesn't do it, they will then need replacing. I hope this gets you straightened out, John 3:16-17 (KJV)

Our air suspension on our 2007 Mercedes r350 have stopped lifting

Your air pump or air shocks may have quit working. Mine would run but the shocks had an air leak. I had to get new air shocks and yes the air pump was shot so I replaced the air shocks and installed an air line below the license plate. I pump them up with my air compressor about every three months. The pump was too expensive for me.

there should be 2 or 3 similar relays in a cluster either near the firewall or the upper shock tower on the drivers side of the engine area.. one should be the relay you need..the dealer can confirm the spot..

Code P1420 suggests replacing the secondary injection pump relay, where is the relay?

17828/P1420/005152 - Secondary Air Injection Solenoid Valve (N112): Electr. Malfunction Possible Causes
  • Secondary Air Injection Solenoid Valve (N112) faulty
  • Secondary Air Pump Relay (J299) faulty
Possible Solutions
  • Check Secondary Air Injection Solenoid Valve (N112)
  • Check Secondary Air Pump Relay (J299)
The secondary air injection pump relay (J299) is inside the engine compartment, left side, behind air cleaner housing, under a black plastic protective cover you can lift up to reveal it. It's near the brake fluid reservoir beside the odd black plastic cover for the wiring harness beside the shock absorber tower.

Rating my suggestion let's me know how helpful it was correcting your problem. Your rating is truly appreciated and would take the very least of time and effort away from you. Thank you

Rear air ride system is not working , seems there are no aftermarket non air ride shocks available , suggest alternative non air ride shock for this year ?

I hate to break the news to you but there are not any available. If the car needs shocks you have to get the air ride one from a dealer parts department.

The good news is....the shocks are probably not your problem...there are valves and sensors, as well as tubing and a pump...any of which could be the problem.

Btw, I’m available to help over the phone in case u need at

I have a 1996 Mercedes S 320 secondary air pump

Hello I'm an M.B. tech- lot's of people have had dificulty with that code. The code means just what it means insuficiant air flow. The egr system does the same thing. What generaly ends up being the problem is a clogged port in the engine head. Unfortunatly on the air pump the port is near the exhaust side of the deck and you must remove the head to repair it where as the egr you can clean the port at the throttle motor. First thing you need to do is make sure there are no more codes in the system. The way that the ecu moniters the operation of the air pump is map senser for vac to the switcthover valve which is the same switch over valve for the egr located in the front of the cam cover. Next it will use the front o2s to moniter the airflow. Also it moniters the airpump relay operation. Operation is started during open loop by the coolant temp. senser. I beleive that this vehicle could possibly have a diagnostic mod along with the engine ecu which moniters the ecu performance. This also needs to be scanned for codes, They discontinued these in late 95. Make sure you have source vac, to the switchover valve-next moniter switchover valve otlet to diverter valve during air pump operation. To properly moniter o2 sensers you will need the proper equipment. Inspect all the airpump plumming as well. assuming the air pump is getting power and operating properly. I would recommend taking the vehicle to an M.B. repair shop and have the system function tested and scanned-with a flow check for the clogged air injection ports. Depending on how many miles I would just do a valve job. If you have any more questions just post and I will get back to you
