Description
Negative Battery Cable for e-HDi Engines for Citroën and Peugeot Vehicles.
This negative battery cable (ground strap) is a direct-fit solution for 1.6 e-HDi powertrains in Citroën and Peugeot models. Designed to restore a solid ground connection between the negative battery terminal and the vehicle chassis/engine, it ensures reliable starting, correct charging system operation and stable electronics behavior. The cable matches common OEM reference numbers used across Stellantis passenger cars and is aimed at professional mechanics and knowledgeable DIYers who search by part number for fast identification.

Installation Recommendations
Always follow safe workshop practice. Before starting, switch off the ignition and remove any metal jewelry. Disconnect the battery: negative terminal first and reconnect last. Inspect mating surfaces (battery post and chassis lug) and clean corrosion before fitting the new cable. Route the cable along the original path, secure any clips or retainers to avoid chafing, and ensure tight, corrosion-free terminal connections. Apply a thin layer of anti-corrosion compound if available. After installation, check charging voltage and verify that starter and onboard electronics operate normally.
How To Replace (Overview)
- Switch ignition off. Remove key.
- Disconnect battery negative terminal first to avoid short circuits.
- Loosen and remove the old ground cable from the battery post and its chassis/engine mounting point.
- Clean contact surfaces, remove corrosion and dry thoroughly.
- Install the new cable, secure clamps and mounting bolt(s), and ensure correct routing and strain relief.
- Reconnect battery negative terminal last and test electrical system.
Most Common Failure Causes
- Corrosion at terminals due to acid fumes and moisture leading to increased resistance.
- Mechanical fatigue or breakage from vibration, rubbing or improper routing.
- Poorly crimped or loose terminals that generate heat and degrade the connection.
- Water ingress accelerating corrosion on connectors or cable ends.
Symptoms Of A Faulty Ground Cable
- Difficulty starting or intermittent starter engagement.
- Erratic electrical behavior, flickering dash lights or warning lamps.
- Battery not charging properly or frequent low-voltage issues.
- Unexplained fault codes related to sensors or ECU grounding.
Recommendations
If you are a professional mechanic: verify fitment by part number, inspect all ground points during any electrical repair and replace any cable showing corrosion or damage. If you are a DIYer: only attempt replacement if you are comfortable working on vehicle electrical systems and have basic hand tools. When in doubt, seek assistance from a qualified workshop.
