2004 Mercedes-Benz SL500 Problems

Stalling and/or "Crank no Start" Due to Failed Crankshaft Position Sensor

The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.

Poor AC performance Due to Evaporator Temperature Sensor Failure

The evaporator temperature sensor can fail, causing the AC compressor not to cycle. If the AC compressor does not turn on, the AC system will not blow cold air. If the compressor is stuck on, the air will be very cold at first, before warming up.

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.

2004 Mercedes-Benz SL500 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.

2004 Mercedes-Benz SL500 Reviews

Purchased 2004 with relatively low miles in April 0f 2011. As of March, 2012, it has become a nightmare. Invested over $5k in 2011 to fix issues that were missed in the pre-certification checkout process. Now, leaking hydraulic suspension, leaking hydraulic convertible top, and shoddy performance have me looking at an $8k repair bill, (on top of the roughly $6k spent last year.), for a woppi...
