2003 Mercedes-Benz E320 Problems
Instrument cluster displays tend to fail, especially the clock and gear indicators. Our technicians tell us the instrument cluster will require replacement to correct this issue.
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.
The cup holder in the center console may break.
2003 Mercedes-Benz E320 Questions
I had the fuel pump replaced and the water pump as well .
I was told that I needed a antifreeze drain and fill for $100 is this right and necessary?
Fuel pump was replaced but then was told I needed fuel pump "wiring" for $50 extra on top of the fuel pump cost ?
After coming to a complete stop and aggressively pressing the gas pedal, the car failed to speed up for 20 to 30 seconds. Then it picked up speed. My suspicion is the Throttle position sensor is failing but I never received an error code on the dash.
2003 Mercedes-Benz E320 Recalls
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.
2003 Mercedes-Benz E320 Reviews
The MB E320 is a great car overall, we have been very pleased with it since buying it used last year. Pros: Very comfortable, yet responsive ride. Handles the snow surprisingly well. Huge trunk and reasonably spacious back seat. Fits 3 in a pinch. Solid feel, good fit and finish, and a great safety record. Better gas mileage than I expected. We get 30+ on the highway with the V6. Cons: Repair...
