PORSCHE CAYMAN 718 GTS 2.5 S 982 2.5L DDN Engine Control Unit Set
Porsche 718 (982) Cayman GTS/S with the 2.5L DDN engine uses a significantly more advanced architecture than earlier models. This setup utilizes the Bosch MG1 family of Engine Control Units (specifically the MG1CS008 or similar variants), which features high-level encryption.
Because the 718 is part of Porsche’s modern “connected” ecosystem, a complete Control Unit Set for the DDN engine is more complex than just a DME and a key.
Components of a Complete 982 Security Set
To bypass the “Component Protection” and the Immobilizer without online dealership programming (PIWIS 3 with PPN access), you generally need a matched set containing:
-
DME (Engine Control Unit): Typically located in the rear luggage compartment area or near the engine firewall.
-
BCM 1 (Body Control Module Front): This manages the vehicle’s “handshake” with the keys.
-
BCM 2 (Body Control Module Rear): Often required on newer 718/991.2 platforms for full system synchronization.
-
Key Fobs: At least one (preferably two) original keys from the donor vehicle.
-
ELV (Electronic Steering Column Lock): On many modern Porsches, the steering lock is part of the immobilizer chain.
Technical Specifications (DDN Engine)
The DDN is the high-output 2.5L flat-four with the Variable Turbine Geometry (VTG) turbocharger.
-
Power Output: $350\text{ PS}$ (S) to $365\text{ PS}$ (GTS).
-
Protocol: SENT (Single Edge Nibble Transmission) for many sensors, meaning the ECU communicates with high-speed digital precision compared to the older analog 996/986 systems.
Identification Table
| Part Description | Typical Part Number Prefix | Notes |
| Engine ECU (DME) | 982 906 XXX |
Must match the “DDN” engine code. |
| BCM Front | 9P1 907 063 |
Revision letters (e.g., AH, BK) are critical. |
| Gateway Module | 9P1 907 530 |
Sometimes required for full functionality. |
Important Notes for Sourcing/Selling
-
PDK vs. Manual: The 718 GTS/S relies heavily on CAN-bus communication between the DME and the Transmission Control Unit (TCU). If the donor car was a PDK and the recipient is a Manual, the ECU will throw persistent communication faults unless recoded.
-
Component Protection: Porsche implemented “Component Protection” on the 982 platform. Even with a matched set, some peripheral modules (like the PCM/Infotainment) might “lock” because they detect a change in the VIN across the network.
-
Condition Check: Ensure the DME connectors are free of any bent pins. The high pin density on the Bosch MG1 makes them much more fragile than the older 964 or 996 units.
