Description
Control unit for Peugeot 308 1.6 e-HDi Start-Stop. 100% functional.
This Continental SID807EVO engine control unit (ECU) is intended for Peugeot 308 models equipped with the 1.6 e-HDi Start-Stop system. It replaces the original injection control module and restores engine management, fuel dosing and Start-Stop functionality. Ideal for professional workshops and experienced DIY mechanics looking for a direct-fit replacement by product number (S180123008 / 9800268980 / 9666681180) or cross-reference codes.

Installation and Coding – Important
- The unit is used and is “paired” with the original vehicle (VIN/PIN/keys).
- Options for commissioning:
- Cloning data from the old unit (EEPROM/Flash) – after cloning the unit is plug and play.
- Virginization and subsequent initialization/telecoding via DiagBox (or online) + key adaptation.
- Recommended to be performed by a technician with PSA service equipment (DiagBox/Lexia/PP2000).
- Always disconnect the battery before removal/installation and follow the manufacturer’s procedure to avoid damaging the unit.
Recommendations For Installation
Recommended steps for replacement (general guidance for experienced technicians):
- Park the vehicle on a flat surface, engage parking brake and disconnect the negative battery terminal before starting.
- Locate the ECU (position may vary by model/year); gain access by removing trim panels or glovebox as required.
- Release connector locks carefully, avoid pulling on wiring, and inspect connector pins for corrosion or damage.
- Remove mounting screws and extract the unit. If cloning, keep the old unit and connect to cloning tool before installation of the replacement.
- Reinstall in reverse order, reconnect battery only after all connectors and fastenings are secured.
- Perform required cloning or telecoding/initialization with appropriate PSA diagnostic equipment to restore full functionality.
Common Reasons For Failure
- Water ingress or corrosion at connector pins leading to intermittent faults or total failure.
- Thermal stress and aging of electronic components after long service life or repeated Start-Stop cycles.
- Voltage spikes, poor battery/charging system condition or jump-start incidents damaging internal electronics.
- Poor connector contact or damaged wiring harness causing communication errors and fault codes.
Typical symptoms of a failing injection ECU: engine warning light (MIL), rough running, stalling, loss of Start-Stop operation or no-start condition. Replacing the unit without proper cloning/coding may leave the vehicle non-functional; follow the Installation and Coding instructions above.
