Airmatic Problem

W211

Hi, Got into car this morning turned on ignition and was met by warning on dash to Visit Workshop and picture of car with arrow pointing up!

Having found out problem related to Airmatic suspension, looked round car and found nearside rear wheel under the arch!

Used the raise car button beside gear selector lever but nothing happening although led operating next to button. Checked main 40A fuse underneath carpet of drivers footwell, ok.

Located pump behind arch of passenger side, wiring all looks intact with no evident signs of corrosion.

There are 2 plugs for the pump, I take it the main power is the 2 white cables which harness to a connector with red/brown cables?

Disconnected harness, started the car, pressed the raise car button to force pump on and with the harness disconnected I checked for power and none present, thought I should at least have 12 volts here??

Would the next step be the Relay and if so which one is it?


Thanks in advance!

Bill

Carried out hard reset of ECU by disconnecting battery for 30 minutes, suspension has sorted itself out, however I think there may be a problem with rear sensor.

Will keep an eye on it and report back

Once the ground cable has been disconnected, it does not make any difference if the positive cable would also be disconnected.
