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.
Detailed Purpose & Benefits
This utility is designed to solve the common fault code "2FA4 incorrect data record." After resetting the working hours, you can successfully perform default coding on the DME, align it with the car's security module (CAS/FEM/BDC), and permanently eliminate the error. This also enables further coding possibilities, such as changing the Power_class after an engine swap or applying software patches.
