2004 Peugeot 307 1.4 16V 90 Manual FWD Gasoline FAQs: Troubleshooting Common Problems & Solutions

• Why does my 2004 Peugeot 307 1.4 16V 90 sometimes have random electrical issues, like lights staying on or wipers acting strange?

  Electrical quirks are, unfortunately, a known characteristic of these early 307s. Often, it traces back to the BSI (Built-in Systems Interface) module, which controls a lot of your car’s electronics. It can be quite sensitive to moisture, perhaps from a windscreen seal that isn't quite right. Sometimes, simply ensuring the area around the BSI, usually near the glovebox, is dry can help. If it's acting really odd, like wipers moving with the car off, it's worth having a technician check for water ingress or a faulty module. A strong battery and healthy alternator are important too!

• I hear a squealing noise from my 2004 Peugeot 307's engine bay, especially when driving. What could be causing this?

  That squealing sound you're hearing from the engine bay, especially if you also notice some wear on the pulleys, very often points to an issue with the alternator pulley wheel bearings. It's really important to get this looked at sooner rather than later. If those bearings fail completely, it could lead to much more significant engine damage. A mechanic can confirm if it’s the bearings or perhaps just a worn drive belt needing a simple replacement.

• My indicators on my 2004 Peugeot 307 1.4 16V 90 are behaving erratically or making a clicking sound; what's wrong?

  A clicking noise coming from the steering column, or if your indicators are just not working as they should, is a pretty common sign that your steering column stalk assembly is nearing the end of its life. This unit, sometimes called the COM2000, handles various controls, and the internal contacts can wear out. While some brave souls try repairing them, it often requires replacing the entire stalk assembly to ensure reliable operation. It's a job best left to someone familiar with these systems.

• What causes a knocking noise from my 2004 Peugeot 307's suspension, especially over bumps?

  If you're noticing a knocking sound from the suspension, particularly when you go over rough patches or speed bumps, it's a common sign of worn components. For your 2004 Peugeot 307, the usual culprits are often the suspension bushes or the anti-roll bar link. Over time, these parts wear down, leading to that distinct knocking noise. It's a good idea to have a mechanic inspect the front and rear suspension to pinpoint exactly what needs replacing for a smoother, quieter ride.

• My electric windows in the 2004 Peugeot 307 1.4 16V 90 aren't working properly; what should I check?

  It's quite a frequent complaint for the 307 when the electric windows act up, either not moving up or down, or getting stuck. More often than not, this issue points to a faulty window motor for that specific window. Sometimes, the internal mechanism can also seize or break. If your window is unresponsive, checking the motor is the first step. You'd likely need to replace the motor unit for the affected window, which involves carefully removing the interior door panel to access it.
