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.

Technical Information

• Manufacturer: Continental
• Model: Peugeot 308 1.6 e-HDi Start-Stop
• Product Codes: S180123008, A 9800268980, 9666681180
• Other Numbers: 1607488880, 1677627080, 1607488980
• ECU Type: SID807 EVO (Injection Control Unit)

Installation and Coding – Important

• The unit is used and is “paired” with the original vehicle (VIN/PIN/keys).
• Options for commissioning:
  1. Cloning data from the old unit (EEPROM/Flash) – after cloning the unit is plug and play.
  2. 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.

As a part of the engine management system, the ECU continuously monitors various parameters to adjust fuel delivery and ignition timing, contributing to improved fuel economy and reduced emissions. Regular replacement of the ECU may be necessary due to wear and tear from heat and vibration, leading to potential failures in engine performance.

Changing the ECU typically involves disconnecting the battery, removing the old unit, and installing the new one. It is advisable to reprogram the new ECU to ensure compatibility with the vehicle’s specific specifications.
