What causes the Peugeot 308 to fail to start with a clicking sound?

The reasons why the Peugeot 308 fails to start and makes abnormal noises are as follows: Gear not in P position: Many car owners start the car without the gear in P position. This situation does not occur with manual transmissions, but mostly with automatic transmissions. This is usually caused by the owner's carelessness, as automatic transmissions do not require frequent operation of the gear lever, making it easy to forget to put it in P or leave it in N. When starting the car, simply ensure the gear is in P position. Steering wheel not unlocked: If the steering wheel is not straightened when parking and turning off the engine, it will automatically lock. When starting the car again, the steering wheel may not turn, causing the car to fail to start. The solution is to turn the steering wheel slightly in the locked direction, then turn the key and start the vehicle.

My Peugeot 308 won't start and is making a clicking sound? I just helped a neighbor diagnose a similar issue two days ago. The key is identifying where the sound originates—if rapid 'clicking' comes from the engine bay, it's likely the starter solenoid engaging and disengaging repeatedly. Common causes lie in the power supply: when battery voltage is insufficient, the starter can't turn the crankshaft and freewheeling creates this rhythmic noise; loose battery terminals causing poor contact may also trigger intermittent current. First test by turning on headlights—if they dim dramatically like candlelight upon activation, it strongly indicates a weak battery. If the battery was recently replaced, inspect starter circuit connections for corrosion (greenish deposits).

The ticking sound during ignition in older 308 models is quite common. As a mechanic with ten years of experience, I recommend a three-step troubleshooting process: First, check the battery voltage—it should be above 12.6V; if it's below 12V, it might not power the starter. Second, inspect the ground wire. The black grounding cable on the left side of the engine bay is prone to oxidation—remove it and sand the connection points with sandpaper. Third, check the starter relay, a blue square labeled '15' hidden in the fuse box. If it rattles when shaken, it needs replacement. The starter's carbon brushes can also cause ticking when worn, sounding like a telegraph machine—if so, it's time for a workshop inspection.

I know that Peugeot's rattling sound all too well! The principle is that the starter motor gear isn't engaging with the flywheel ring gear. When you turn the key, the starter pinion should 'click' out to mesh with the large gear. If the battery is low on charge or the starter's internal fork is rusty, the pinion won't spring into place properly and will frantically strike the edge of the ring gear, producing a rapid metallic knocking sound. This is particularly common in winter, especially when temperatures drop below freezing as the gear oil thickens more severely. For emergency treatment, you can ask a friend for a jump start, but it's best to check the starter solenoid as soon as possible. The starter on this older 1.6L engine model is indeed prone to this issue.

Last month, my 308S had the same issue, making a tapping sound like a woodpecker. Focus on checking three key areas: First, the battery must be prioritized—Peugeot is extremely sensitive to voltage, and even 12.1V can cause starting difficulties. Second, check the F4 fuse (30A) in the fuse box, which specifically controls the starter—use a test pen to see if there’s current on both ends. The most troublesome issue is wear in the ignition switch; if the internal contacts are faulty when the key is turned to the START position, it can cause intermittent current. Here’s a handy trick: Have a friend turn the key to start the car while you lightly tap the starter housing with a hammer—sometimes the vibration can help a stuck gear reset.

That sound is like the 'click' when a lighter can't be pressed down, right? Essentially, it's the starting circuit intermittently connecting and disconnecting. Apart from battery issues, the aging engine wiring harness in the Peugeot 308 is particularly problematic. The high temperature in the engine compartment can make the insulation of the red and black power supply wires to the starter brittle, causing poor contact when the copper strands inside break. Additionally, the anti-theft system acting up can also prevent starting, indicated by a small key icon flashing on the dashboard when turning the key. If this happens, try locking the car for ten minutes to reset the system. Also, a reminder: when you hear the clicking sound, never attempt continuous ignition for more than 5 seconds to avoid burning out the starter motor coil!
