A code 170 on a Mercedes SLK 230 typically indicates a problem with the fuel trim, often related to a lean running condition. To fix this issue, start by checking for vacuum leaks, inspecting the intake system, and examining the mass air flow (MAF) sensor for proper function. Additionally, ensure the fuel pressure is within specifications and that the fuel filter and injectors are clean. If these components are functioning correctly, consider checking the engine control unit (ECU) for updates or faults.
