Active Body Control System Can Leak Hydraulic Fluid

The active body control system can leak fluid from numerous areas, including the tandem pump, hydraulic lines, struts, and/or seals. If it is not repaired, the vehicle ride height could drop too low and cause damage to the undercarriage.

Leaks in the pneumatic system will cause problems with the dynamic seats and the trunk and/or door closing assist.

2003 Mercedes-Benz SL55 AMG 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 have only owned my 2003 SL55 AMG for about a week and these reviews scare me. I hope only those who have problems write these reviews and that many of these SL55s are very reliable and don't have many problems. If any of you reading this have had good luck and not many problems, please comment before I decide to sell mine, I love it so far but these comments scare me, I'm not rich. Dr...
The most unreliable car I've ever owned. Here is the abbreviated version of my car's failure list since I purchased it with 42K miles about 2 years ago (now about 60K miles): Supercharger pulley bearings broke, idler pulley bearings broke, closure panel for folding hardtop failed (other roof closure trim broke and came off), ABC suspension has failed and required major work twice, shifter has f...
We loved ours, until it spontaneosly set itself on fire two weeks ago-July 2012. It had not been driven in a week and was parked in a garage when an electrical fire occurred behind the passenger side and smoldered the interior. Luckily, someone happened to be in the garage and noticed it at 2AM and called the fire department. No one was injured and only our car was severely damaged. Still w...
