Problem: 2009 Smart Fortwo experiencing P0805 code, squeaky/scratchy noise when starting with clutch pressed, and slipping clutch on downshifts at 108,000 miles. Owner considering whether clutch and actuator replacement is necessary and whether local shops can perform the work.

Solution: Multiple forum members confirm that there is no specific mileage recommendation for clutch replacement on 451 models; wear varies by driving habits. One user successfully replaced their clutch themselves without software calibration. The original poster had their clutch actuator replaced at 111,431 miles by a local shop (RSW Auto) for $1,000, which resolved the P0805 code and noise issues. The actual clutch was found to still be in acceptable condition. Any competent repair shop with access to Mercedes-Benz software can perform clutch and actuator replacement and recalibration; dealership service is not required. Aftermarket parts like SACHS (OEM supplier) are viable alternatives to dealership parts.
