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.

Mercedes-Benz E320 Reviews

I love my car but this model has some nagging issues. Common problems with the E series are failure of the climate control LCD panel, failure of the LED displays in the instrument cluster, squeaky steering wheel, and failure of the auto dimming drivers side mirror. Mine has experienced all of theses. The instrument cluster and climate control are so common I feel Mercedes should issue a recall.

I love my Mercedes Benz 2001 E320. It's a great car. There's a little problem. It has this rough sound when I start it and get going, then, once I'm on the road at a set speed it drives very smooth. One mechanic said it was the motor mount then another said it was the air flow in the engine. What to do, what to do?

We have 1997 E320 wtih 300+K miles. Very happy, as it is one of the best and most dependable car. Basic maintance: 1) Change oil (Castrol 10W-30 or 10W-40) + Bosch oil filter every 10,000 miles. 2) Clean K&S air filter very 20K or as needed 3) Replace differential oil - Castrol 85W90 every 50K 4) Replace Bosch fuel filter every 25K-50K 5) Brake flush with Castrol Dot 4 - 50K ...
