2004 Mercedes-Benz E500 ProblemsAirmatic Pump Motors May Fail Due to Sticking Relays
The relay which turns the airmatic suspension pump on may fail causing the pump to run continuously. This can result in failure of the pump motor or a dead battery as the pump motor will continue to run after the car is turned off. Also, Worn airmatic pump mount bushings can causes noises in the front axle while driving on bumpy roads or a buzzing noise while the pump is running.
Rear air springs (bellows) may develop leaks, which causes the air pump to run more often to maintain ride height. Our technicians recommend that leaking air springs be replaced.
This vehicle has sensotronic brake control (SBC). If the SBC light on the dash illuminates, have the brakes checked. If the SBC is not working, limited brake pressure is delivered to the front brakes, increasing the distance it takes to stop. The SBC hydraulic unit has a specific service life programmed into the control module; follow the manufacturer's recommended service procedure for proper maintenance of the SBC.
2004 Mercedes-Benz E500 Questionscar has been sitting in the garage for two years. Had Half a tank of gas. (1 answer)

2004 Mercedes-Benz E500 RecallsIncorrect Software Calibration May Cause Fuel Pump to Remain Powered in a Collision
There is a faulty software calibration that affects several areas including shutting off the fuel supply in a collision. This could cause a fire hazard during an accident. Dealers will reprogram this software. The Mercedes-Benz recall number is 2008 070001. This recall began during August, 2008.
Due to deterioration of the wiring harness connection or failure of the hydraulic pump, the sensotronic brake control (SBC) system may default to the hydraulic back-up mode. In the back-up mode, the driver has braking power sufficient to stop the vehicle, but greater brake pedal pressure is required and brake pedal travel will be noticeably longer. Dealers will install a bracket and replacement ground wire to the SBC pump unit on all affected vehicles. Additionally, dealers will inspect and replace the SSC pump unit in certain SL models. The Mercedes-Benz recall numbers are 2005070007 AND 2005110001.
High mileage combined with a high number of brake actuations, or a high brake actuation frequency, can cause the pump motor of the SBC to run out of permissible tolerances. As a result, excessively high pressure may build the high pressure line of the brake system. If this occurs, the system will switch into the hydraulic function mode as designed. Sensotronic brake control is disabled when the brake system is functioning in the hydraulic mode. Dealers will inspect the SBC hydraulic unit and replace it if necessary to correct this concern. The Mercedes-Benz recall number is 2004 050014.
