Mercedes-Benz SL55 AMG Problems
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.
The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.

Newly purchased only 35K miles.
Replaced starting battery with new one.
Starter clicks and engages, can see engine move 1/4 inch or so then nothing. Can turn engine with socket.

Mercedes-Benz SL55 AMG 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.
Transistors used in the front signal acquisition and actuation module (SAM-F) may have been damaged during module assembly. As a result, the module could fail without warning, increasing the risk of a crash. Dealers will inspect and replace the affected modules as necessary. This recall is scheduled to begin on May 2, 2008. The Mercedes-Benz recall number is 2008 030005.
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 transition is pure magic. Son - park your motorbike. Yo...
