Product Overview

High-quality Valeo CL15 alternator compatible with a range of Citroën and Peugeot 1.6 e‑HDI applications. This unit is a direct-fit electrical component commonly sought by mechanics and DIY enthusiasts by its OEM reference numbers. The listing includes the most relevant product codes to help you find the exact replacement quickly. Ideal for replacing a failing alternator to restore reliable charging and electrical system performance.

Function And Symptoms

The alternator charges the battery and powers onboard electrical systems while the engine runs. Typical symptoms of a failing alternator include:

• Battery warning lamp or dashboard charging symbol illuminated.
• Dimmed headlights or fluctuating interior lighting.
• Frequent jump-starts or a battery that discharges quickly.
• Unusual whining or grinding noises from the front of the engine (bearing wear).
• Intermittent electrical faults or stalling at idle due to insufficient charging.

Replacement Procedure

Simple mechanical and electrical steps for an experienced mechanic or competent DIYer:

• Always disconnect the negative battery terminal before starting work.
• Relieve tension and remove the drive/serpentine belt.
• Disconnect electrical connectors and remove the alternator mounting bolts.
• Fit the replacement unit, secure mounting bolts and reconnect electrical plugs.
• Refit and tension the drive belt to manufacturer specification.
• Reconnect the battery and verify charging system operation (voltage output at idle and rev).

Installation Recommendations

To ensure reliable operation after fitting:

• Inspect Belt And Pulleys: Replace worn belts or pulleys to avoid premature alternator wear.
• Check Battery Condition: A weak or faulty battery increases alternator load and can shorten its life.
• Clean Connections: Corroded or loose terminals reduce charging efficiency—clean and tighten all connections.
• Use Correct Tools: Use proper socket sizes and follow vehicle maker procedures for belt tensioning and torque values.
• After Installation: Verify charging voltage (typically ~13.8–14.6 V with engine running) and check for abnormal noises.

Most Common Failure Cause

Alternators usually fail due to mechanical wear or electrical component faults. The most frequent issues are:

• Bearing Wear Leading To Noise And Seizure.
• Diode Or Rectifier Failure Causing Poor Or No Charging.
• Voltage Regulator Malfunction Resulting In Overcharging Or Undercharging.
• Contamination From Oil, Coolant Or Road Debris Reducing Component Life.
• Excessive Load From A Weak Battery Or Faulty Electrical Accessories.

Ideal when restoring engine performance, resolving loss of power, excessive smoke or poor fuel economy caused by a worn or damaged turbo.

Technical Information

Manufacturer: Stellantis
Model: 1.5 HDI 75 kW (used on Citroën, Peugeot, Opel, Fiat and Toyota applications)
Product Codes: 9813245480, 1631887280, 49172-03100
Additional Numbers: Mileage From Donor Vehicle: 64,000 km

Compatibility (Typical Vehicles)

• Citroën Berlingo III (with 1.5 HDI 75 kW)
• Peugeot Partner III (with 1.5 HDI 75 kW)
• Peugeot Rifter (with 1.5 HDI 75 kW)
• Fiat Doblo III (with 1.5 HDI 75 kW)
• Opel Combo E K9 (with 1.5 HDI 75 kW)
• Toyota ProAce City (with 1.5 HDI 75 kW)

Function and Benefits

The turbocharger increases intake air pressure to improve combustion efficiency, torque and overall engine power. Replacing a degraded turbo restores throttle response, reduces excessive smoke and can improve fuel consumption. This unit uses original-equipment mounting interfaces and oil/coolant feed connections for direct fitment on compatible 1.5 HDI installations.

Typical Replacement Procedure

Recommended for experienced mechanics or skilled DIYers. General steps include:

• Disconnect the battery before starting work.
• Remove intake ducting, intercooler connections and relevant sensors to access the turbo.
• Undo the oil feed and return lines (catch all residual oil) and any coolant lines if present.
• Unbolt the turbo from the exhaust manifold and from the downpipe; support the turbo when separating to avoid strain on pipes.
• Fit new gaskets and seals (use OEM-quality replacements). Mount turbo and tighten fasteners to manufacturer torque specifications.
• Prime the turbo with oil where possible before initial start-up. Reconnect all lines, refill engine oil if drained and inspect for leaks.
• Start engine and monitor oil pressure, boost response and exhaust for abnormal noises or leaks. Allow engine to idle and reach operating temperature before test driving.

Installation Recommendations

Always follow manufacturer safety procedures and service manual instructions. Replace oil and filter or ensure clean, correct-grade oil is used when fitting a turbo to prevent premature wear. Use new gaskets and ensure oil feed/return lines are clean and free of debris. Inspect intercooler and intake for carbon or foreign objects. After installation, allow the engine to idle to verify oil pressure and absence of leaks before driving. For best results, perform a short, gentle break-in and recheck fasteners after initial service interval.

Why This Part Commonly Fails

Turbochargers typically fail due to oil-related issues (contaminated oil, oil starvation or blocked oil return), foreign object damage from intake or exhaust sides, excessive soot buildup from poor combustion or EGR problems, and wear of bearings over time. Heat cycling and insufficient warm-up/cool-down procedures (hard driving immediately after cold start or shutting the engine off hot) also shorten turbo life. Regular oil changes with the correct specification and ensuring clean oil and intake systems significantly extend turbo service life.
