Repair manuals and video tutorials on PEUGEOT 307

Engine

• The mass airflow sensor wears out fast in diesel engine models. If this happens, an insufficient or excessive amount of fuel is supplied to the combustion chambers. The signs of a defect are an unstable idling engine rotation speed and power loss at an increased fuel consumption rate. Usually, the check engine light on the dashboard will come on. You can replace the part in your garage. For this you need to download our illustrated PDF manual on Peugeot 307 repair.
• The fuel pressure regulator can break down on HDi engines. This is caused by membrane shrinkage, spring stretching or valve jamming. The engine may stall or malfunction when idling, and the car may jerk while driving. Moreover, fuel consumption increases. Leave the installation of a new regulator to professionals. Use only high-quality fuel and replace the fuel filter in due time to increase the working lifespan of the component. You can do it yourself by following our step-by-step video tutorial on Peugeot 307 repair.

Transmission

• The dual-mass flywheel is prone to breaking down in models equipped with a 2.0 HDi engine. The defect signs are unusual sounds and vibrations when starting and skidding when driving. The problem can only be solved only by having the part replaced at a garage.
• A worn manual gearbox lever can become loose, leading to difficulty shifting gears. Installation of a new part is necessary in this case. Our recommendation is to avoid aggressive driving in future.
• Cables of a manual transmission can sometimes get stretched or torn. Usually this happens in winter: in cold weather, the oil thickens and more effort needs to be applied to the lever. The whole cable set needs to be replaced together even if only one of them is stretched. This guarantees stable operation of the unit. Have these components installed by specialists.

Electric equipment

• The BSI unit, which is responsible for operation of the vehicle’s electronic systems, can fail due to moisture ingress. If this happens you can dry the unit, or replace it if that doesn’t work. This job won’t be any trouble if you download our step-by-step instructions on Peugeot 307 repair and maintenance for free.
• A turn signal switch may not return to the initial position or may malfunction due to thermal damage to contacts and plastic elements. The switch is usually replaced as a whole unit. You can do this yourself with the help of our video guide on DIY Peugeot 307 repair and maintenance.
