Mercedes-Benz ME9.7 Remanufactured ECU – Programmed to Your Vehicle | 3-Year Warranty

Restore reliable engine operation with a remanufactured Bosch ME9.7 engine control unit from LaCorte Automotive. Each unit is inspected, remanufactured, and tested before shipment, with programming options based on your vehicle and original ECU availability.

Service Options

• Cloned replacement: Send us your original ECU so we can transfer the required vehicle data to a compatible remanufactured unit. When the original data is recoverable and compatible, your replacement arrives ready for plug-and-start installation.
• Original ECU missing or unreadable: Contact us before purchasing. Additional vehicle information, components, or programming may be required.

Common Symptoms of ECU Failure

• No-start condition caused by an internal ECU fault
• Intermittent stalling or loss of ECU communication
• Internal control-module fault codes
• Injector or ignition control faults traced to the ECU
• Water damage or damaged internal circuitry

These symptoms can also result from wiring, power-supply, or other vehicle faults. Confirm the diagnosis before ordering.

Compatibility

For select Mercedes-Benz vehicles equipped with a Bosch ME9.7 ECU, including certain M272 V6 and M273 V8 applications.

Fitment must be verified using your VIN and original ECU part number. Model and engine size alone do not confirm compatibility. Send clear photos of the original ECU label when available.

How It Works

1. Send us your VIN and ECU part number for compatibility verification.
2. Ship your original ECU if purchasing a cloned replacement.
3. We prepare and test your compatible remanufactured ECU.
4. Reinstall the replacement and follow any supplied instructions.

Turnaround & Shipping

Typical processing time is 1–2 business days after receiving your original ECU, subject to stock, compatibility, and data recovery. Shipping time is additional. Customers are responsible for shipping their original module securely packaged.

3-Year Unlimited-Mileage Warranty

Includes a 3-year unlimited-mileage warranty covering defects in the supplied remanufactured ECU. Damage caused by water intrusion, incorrect installation, external electrical faults, or unauthorized modification is excluded.

Please contact LaCorte Automotive before ordering if your original ECU is missing, unreadable, or has previously been replaced.
