Mercedes-Benz E320 Problems

Check brakes if sensotronic brake control (SBC) light comes on

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.

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.

Oil May Leak From PCV Vent Housings and Inspection Plates

An engine Oil leak may develop from the PCV vent housing on the valve cover and/or the inspection plate on the front of the engine.

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.

Mercedes-Benz E320 Reviews

Paid 2500 for it. I've had it almost three years all I've had down is replacement of lower front control arm and bought a battery. Love it rides great. Air condition didn't work when I got it but the heat is a beast and the ride is so smooth even at 120 mph
I have owned my wagon for exactly 13 months. I bought it with 104,000 miles, and I have put over 50,000 miles in that time. Most reliable car that I've ever had. Changed the oil every 7,000 mi (synthetic). Changed the brake pads once (routine maintenance). No expenditures at all. Still looks new. Will eventually put money into it and restore it completely (perhaps in a couple of years or so). ...
Bought this 1997 E-320 only 67 K always covered excellent condition Somehow it has a short that burns the fuse when trying to put it in gear. The fuse that controls the dash gages (gas,speedometer, engin idle,etc) and it says CHECK ENGIN. The radio and the A.C. work and it rides good other than all the gages out. My mechanic has no clue Is it the transmission sensor? Any clues?
