How It Works:

After placing your order, ship your original DME to LaCorte Automotive. We will transfer the required data into the remanufactured replacement module and return it ready for installation.

If your original DME cannot be read, additional programming or vehicle-side synchronization may be required. Please contact us before ordering if your original module is completely unresponsive, missing or severely damaged.

Compatibility:

MS43 modules were produced with several hardware and software versions. Please provide your VIN and a clear photograph of the label on your original DME before ordering so we can confirm compatibility.

Warranty:

This unit includes a 3-year warranty covering defects in the remanufactured module. The warranty does not cover damage caused by water intrusion, incorrect installation, wiring faults, reversed polarity, failed ignition coils, jump-starting or other problems elsewhere in the vehicle.

Important:

The underlying cause of the original DME failure should be diagnosed and repaired before installing the replacement. Faulty wiring, ignition coils, charging-system problems or water intrusion can damage the replacement module.
