2004 Mercedes-Benz E320 Problems

Leaks From Rear Air Springs

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.

Engine Performance Problems Due to Crankshaft Position Sensor Failure

The crankshaft position sensor may fail. Symptoms of this are: The engine will crank—but not start—especially when the engine is warm. The car may start again if it is left to cool off, but it may run roughly or have poor performance.

Brake Light Switch Failure May Cause ESP/BAS Warning Lights

The ESP and BAS warning lights may illuminate due to a failed brake light switch. Replacement of the failed switch should correct this concern.

2004 Mercedes-Benz E320 Recalls

Incorrect 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.

Sensotronic Brake Control System May Default to Basic Hydraulic Mode

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.

 

The Sensotronic Brake System May Be Disabaled

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.

I bought my 2004 E320 wagon in 2010 w/79k on odometer. This is a great car. Very utilitarian. Great gas mileage for a car of it's size. Downside? Lots of expensive repairs. Upside? This car will last a long time and still looks great. 03/13. JJB1895
Bought this car new so I thought. Found out the the car had been wrecked just 2 months before we bought it from Regal Mercedes. Sales managers wife backed her SUV into the front of it when he drove it home for lunch one day. $2900 in damage. The headlights cloud up worse than any other car on the street. Just count them as you pass by.I would not recommend this car to anyone. The ABC system has...
I've had my car for 4 months now. I bought with very low miles considering it was a 2004. I read a lot of horror stories about the 2004 Mercedes, but I really have not seen any problems with my car. It is excellent on the road. The ride is smooth in great weather as well as rainy weather.
