Description
Supply cable to the START-STOP condenser for e-HDi engines.
This OE-compatible feed cable connects the Start‑Stop capacitor/assembly to the vehicle electrical system on selected Citroën and Peugeot models with e‑HDi technology. It is designed to carry the high transient currents associated with Start‑Stop operations and to ensure reliable communication between the capacitor module and the vehicle power network. Faulty or damaged cables commonly cause Start‑Stop malfunction messages, loss of stop/start functionality or intermittent electrical faults.

Fitment And Application
Intended for vehicles equipped with the e‑HDi Start‑Stop system where this feed cable connects the Start‑Stop capacitor (energy storage module) to the vehicle wiring harness. Often searched by part number 9688166980. Suitable for professional workshops and experienced DIY mechanics familiar with high‑current electrical systems.
Installation Recommendations
- Disconnect the battery negative terminal and wait a few minutes to ensure capacitors are discharged before starting work.
- Locate the Start‑Stop capacitor/assembly (refer to the vehicle workshop manual for exact position on the specific model).
- Carefully unplug the electrical connector and remove any retaining clips or fasteners securing the cable.
- Replace the cable with the new unit, ensuring connectors are fully seated and any seals or grommets are correctly positioned to prevent ingress of moisture.
- Reattach all fasteners, reconnect the battery, and perform a system check (Start‑Stop operation and any related fault codes) using suitable diagnostic equipment.
Why This Part Most Often Fails
- Corrosion At Connector Contacts: Exposure to moisture and road salt leads to increased resistance and intermittent contact.
- Mechanical Fatigue: Vibration and movement in the engine bay can cause wire breakage or connector loosening over time.
- Insulation Damage: Heat, chemical exposure or chafing against bodywork can compromise insulation and cause short circuits.
- High Current Stress: Repeated Start‑Stop cycles produce high transient currents that, over long periods, stress connectors and conductor joints.
- Incorrect Installation Or Poor Repairs: Non‑OE replacements or improper routing/termination accelerate wear and failure.
Notes For Purchase
This cable is supplied under OE reference 9688166980 and is a direct replacement for the models listed. If you search by part number, you will quickly locate this exact item. Replacement is recommended when visual damage, corrosion, or Start‑Stop faults are present.
