It's common for the DAS (Immobilizer unit) to fail in Mercedes SL cars, W140 S - Class and C140 CL - Class chassis manufactured from 1994-2009. When this happens, the vehicle is immobilized and usually, ' START ERROR' is displayed in place of the odometer in the instrument cluster.  To address this issue, we developed a solution that eliminates the DAS functionality, enabling the vehicle to start with any cut key, which has proven to be the best solution for this issue.

This solution is highly recommended as DAS units are no longer available and are likely to fail again. Therefore, if you own an W140 S - Class or C140 CL - Class , this is the optimal solution for ensuring reliable performance.
