Brakes, August 8, 2005

RepairPal Expert Overview:

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.

Brakes, October 21, 2004

RepairPal Expert Overview:

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.

Over the last 4-5 days my E320 has lowered itself almost to the ground. More so on the rear than front and more so on the pass side than driver? Any ideas?

markscarb, 2004 Mercedes-Benz E320, West Palm Beach, FL

Are there not several items that could contribute to this? Some being minor and others obviously being major. This appears to be only affecting the pass side rear.

How can I tell if my car has the self leveling system option. I would assume the shocks are different and higher cost with this option??

winton803, 2004 Mercedes-Benz E320, Columbia, SC

Can battery replacement be done other than at a Mercedes dealership? What should it cost at an MB dealership?

2004 Mercedes-Benz E320 Reviews

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 failed once and been repaired and now the suspension is sqeaking AGAIN. Money pit!!

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.

I recently bought a used 04 Mercedes E-320 with 88K + miles on it and was very please with crisp handling and great suspension, comfort, safety and power, it just feels a lot different driving a mercedes than another car. The solid feel of toughness and yet gentle enough as feather.

I bought this wagon for my wife who very much liked the third seat facing aft. While waiting to sell her SUV to by me a BMW, I began driving it to work and to pick up my business guests. Not only do I received endless compliments on the vehicle, I enjoy the practicality of it. It is like having a luxery car, that has a great loading capacity, and receives fantastic gas mileage. My only complaint is the high cost of maintenance at the dealership.
