2002–2005 Mercedes-Benz SL600 V12 ECM | Cloned or Virginized

Replace your Mercedes-Benz SL600 engine computer with a professionally remanufactured ECM (Engine Control Module) from Automobile Computer Solutions (ACS).

Choose Programmed (Cloned) for plug-and-play installation or Virginized for programming by your shop, subject to ECM compatibility and service availability.

Vehicle Fitment

Mercedes-Benz SL600 V12 gasoline engine — 2002–2005, subject to VIN and original ECM verification.

• 2002 Mercedes-Benz SL600 — 6.0L M120 V12 (R129), where applicable by market

• 2003 Mercedes-Benz SL600 — 5.5L M275 Twin-Turbo V12 (R230)

• 2004 Mercedes-Benz SL600 — 5.5L M275 Twin-Turbo V12 (R230)

• 2005 Mercedes-Benz SL600 — 5.5L M275 Twin-Turbo V12 (R230)

Important Engine Differences

The earlier SL600 uses a different engine-management architecture from the later R230 SL600.

The 2003–2005 SL600 uses the 5.5L M275 twin-turbocharged V12, which has two-bank engine management and may require bank-specific control modules and programming.

These ECMs are not interchangeable between the different engine generations.

The 2002 SL600 application requires additional verification because model-year availability differs by market. I cannot confirm universal 2002 SL600 fitment from the competitor listing alone.

Compatibility Verification

Before ordering, please provide:

• Vehicle Identification Number (VIN)

• Original Mercedes-Benz ECM part number

• Original Bosch ECM part number, if available

• Clear photos of the original ECM label

• Confirmation of the engine configuration

ACS will verify hardware compatibility and available programming services before processing the order.

Programmed (Cloned)

For supported modules, ACS transfers the required vehicle-specific data, immobilizer information, and coding from your original ECM to a compatible replacement.

After successful cloning, the replacement ECM is intended to operate with the existing vehicle security system and keys without additional dealer programming.

Note: Some SL600 configurations use separate engine control units for the two cylinder banks. The number of modules requiring replacement must be confirmed before purchase.

If the original ECM cannot be read or cloned, ACS will contact you to discuss available options.

Virginized

Virginizing is available for supported ECM part numbers.

The replacement ECM is prepared for programming, coding, and immobilizer synchronization by a qualified automotive technician.

Mercedes-Benz diagnostic equipment and additional programming procedures may be required.
