BMW Working Hours Resetter - 2FA4 Error Fix​#

What This Tool Does (In Simple Terms)

When a used engine computer (DME/ECU) is installed in a BMW, the car often rejects it. This happens because the 'working hours' stored in the used unit don't match the car's actual mileage, causing a persistent '2FA4' error.

This tool resets the working hours in the used DME back to zero. This "resets" the computer, allowing a technician to then program it to the car as if it were a new part, completely fixing the error.
