Peugeot 108 Clutch & Brake Light Guide

The Peugeot 108, a popular choice for city driving and small families, relies on a well-maintained clutch for smooth gear changes and a functional third brake light for safety. While many owners opt for professional servicing, understanding the basics of these components can empower you to tackle minor issues or at least be more informed when discussing repairs with your mechanic. This guide will delve into the intricacies of replacing the clutch and the seemingly simple, yet crucial, task of changing a third brake light bulb on your Peugeot 108 (2014-2021, MK 1).

Understanding Your Peugeot 108's Clutch

The clutch is a vital component in any manual transmission vehicle, acting as the link between the engine and the gearbox. It allows you to disconnect the engine's power temporarily, enabling you to change gears smoothly. When the clutch pedal is pressed, a mechanism disengages the clutch, and when released, it re-engages, transferring power to the wheels. Over time, the clutch can wear out, leading to symptoms like slipping, difficulty engaging gears, or a spongy pedal feel. Replacing a clutch is a significant undertaking, typically involving the removal of the gearbox and several other components. It's a job that requires specialised tools, a good understanding of mechanics, and a safe working environment, often best left to experienced professionals.

Signs of a Worn Clutch

Before embarking on a clutch replacement, it's essential to recognise the signs that indicate your clutch may be failing. These can include:

• Clutch Slipping: The engine revs increase, but the car doesn't accelerate proportionally. This often manifests as a burning smell.
• Difficulty Changing Gears: You might experience resistance when trying to shift into a particular gear, or the gear may not engage at all.
• Spongy or Stiff Clutch Pedal: A clutch pedal that feels unusually soft, has a lot of free play, or is excessively stiff can indicate hydraulic issues or a problem with the clutch mechanism itself.
• Grinding Noise: A grinding sound when engaging gears, particularly first or reverse, is a strong indicator of clutch wear.
• Burning Smell: A distinct burning odour, often described as burnt toast or rubber, usually signifies overheating clutch components.

The Clutch Replacement Process (Overview)

Replacing the clutch on a Peugeot 108, like most front-wheel-drive vehicles, is a labour-intensive process. While a step-by-step DIY guide is beyond the scope of a general article due to its complexity and safety implications, here's a general overview of what's involved:

The process typically begins with safely lifting and supporting the vehicle. Key steps include:

• Draining the gearbox oil.
• Disconnecting various components, such as the driveshafts, exhaust system, starter motor, and clutch slave cylinder.
• Supporting the engine and gearbox assembly.
• Removing the gearbox from the vehicle.
• Unbolting and removing the old clutch pressure plate and clutch disc.
• Cleaning the flywheel surface.
• Installing the new clutch disc and pressure plate, ensuring correct alignment.
• Replacing the clutch release bearing (and often the spigot bearing).
• Reinstalling the gearbox.
• Refilling the gearbox with fresh oil.
• Reconnecting all previously disconnected components.
• Bleeding the clutch hydraulic system if necessary.

Important Note: Due to the intricate nature of this repair, the need for specific tools (like a transmission jack and clutch alignment tool), and the potential safety hazards involved, it is highly recommended that clutch replacement be performed by a qualified mechanic. Attempting this without the necessary expertise could lead to further damage or personal injury.

Replacing the Third Brake Light Bulb

The third brake light, also known as the high-level brake light, is crucial for signalling your intentions to drivers behind you, especially during braking. Replacing its bulb on the Peugeot 108 is a much more accessible task for the average car owner.

Locating the Third Brake Light Assembly

The third brake light on the Peugeot 108 is typically integrated into the rear spoiler or above the rear window. To access the bulb, you will need to open the rear hatch of the car.

Step-by-Step Bulb Replacement

Follow these steps to replace the bulb:

1. Open the Rear Hatch: Ensure the rear hatch is fully open.
2. Locate the Cover: Inside the hatch, look for a black plastic cover or panel that conceals the third brake light assembly. This might be held in place by clips or small screws. You may need a trim removal tool or a small flathead screwdriver to gently pry it open.
3. Access the Bulb Holder: Once the cover is removed, you should see the bulb holder. This is usually a plastic component that twists or pulls out of the light housing.
4. Remove the Old Bulb: Gently pull the old bulb straight out of its holder. Be careful not to force it.
5. Insert the New Bulb: Take your new, compatible bulb and insert it firmly into the holder. Ensure it's seated correctly. The Peugeot 108 typically uses a specific type of bulb, so it's essential to consult your owner's manual or a parts supplier to confirm the correct part number (e.g., a specific wattage and base type).
6. Reassemble: Reinsert the bulb holder into the light housing, twisting or pushing it until it clicks into place. Replace the protective cover, ensuring it's securely fastened.
7. Test the Light: Close the hatch and have a helper press the brake pedal while you check from the outside to ensure the new bulb is working correctly.

Important Considerations for Bulb Replacement

• Correct Bulb Type: Always use the correct type of bulb. Using the wrong wattage or type can damage the wiring or the light assembly, or it may not function correctly. Your Peugeot 108 owner's manual is the best resource for this information.
• Handle Bulbs with Care: When handling new bulbs, especially halogen ones, avoid touching the glass with bare fingers. Oils from your skin can cause the bulb to overheat and fail prematurely. Use a clean cloth or gloves.
• Check Other Bulbs: While you're there, it's a good idea to check the other brake light bulbs to see if they are also dim or nearing the end of their life. Replacing them simultaneously can save you another trip to the car soon.

Troubleshooting the Third Brake Light

If the new bulb doesn't work, consider these possibilities:

• The new bulb is faulty (rare, but possible).
• There's a problem with the bulb holder's connection.
• There's an issue with the wiring or the brake light switch.
• The fuse for the brake lights has blown. Consult your owner's manual for the fuse box location and the specific fuse for the brake lights.

Maintenance Schedule and Tips

Regular maintenance is key to ensuring the longevity and performance of your Peugeot 108. While clutch replacement is a major repair, routine checks can help prevent premature wear. For the third brake light, simply being aware of its function and replacing bulbs promptly contributes to your vehicle's safety.

Clutch Care:

• Avoid resting your foot on the clutch pedal while driving, as this can cause unnecessary wear on the release bearing and clutch components.
• Do not 'ride' the clutch – engage it fully when moving off and disengage it fully when stopping.
• Ensure you are in the correct gear for your speed to avoid unnecessary strain on the clutch.

Brake Light Checks:

• Make it a habit to check all your exterior lights regularly, including the brake lights, headlights, and indicators. This is a simple yet vital safety check.
• Clean the lenses of your lights periodically to ensure maximum visibility.
