2004 Mercedes-Benz SL55 AMG Problems

Flush Brake Fluid Every Two Years

The anti-lock brake system (ABS) modulator assembly may fail due to dirty brake fluid. Our technicians recommend a complete brake system flush every two years in order to help prevent this problem.

Front Thrust Arm and Control Arm Bushing Can Crack or Tear

Front thrust arm and control arm bushings can crack and sometimes tear completely. If this is not repaired quickly, damage to the front subframe unit will occur, which is very expensive to repair. Updated control arms (that prevent damage to the subframe when the bushings wear out) are available.

Cracked Driveshaft Flex Discs May Cause Driveshaft Movement/Vibration

A vibration felt through the center floor of the vehicle can be caused by driveshaft flex discs, which crack and shred, causing excessive driveshaft movement. Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential.

2004 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 can't stop smiling. UNMATCHED beauty and performance. Several people have complimented me once, twice then a third time on how beautiful this car is. I agree. Undoubtedly destined to become a classic, this car is as docile as a kitten until called upon to perform. Then it becomes a well controlled beastly powerful driving machine! The transition is pure magic. Son - park your motorbike. Yo...
Great car. MB need to do more R@D on the suspention. Have had to replace the supention flud pump with 90,000 miles on car. 3800.00. And has a gear shift lock out problem that will not let you shift the car out of park, 1200.00. You wold expect a car that cost that much to live up to the MB reputation for relibinlty.
