Exhaust Renault Laguna

Renault Laguna owners often experience issues such as vibrations, unusual noises (knocking, humming), suspicious smells, and blockages. These problems frequently relate to components like the oxygen sensor (lambda sensor), EGR valve, or leaks in the exhaust line.

Common reported symptoms and their causes include :

• Engine warning light on, irregular engine running, abnormal exhaust smell – often caused by a faulty lambda sensor located before or after the catalytic converter. Other causes: EGR valve, particulate filter, or damaged exhaust pipe.
• Vibrations and noise at idle around 800 rpm which stop at acceleration – usually due to a defective exhaust mount or loose fixing.
• Blocked exhaust causing power loss in cold short trips, especially in snowy weather.
• Knocking noises from the exhaust system detected while driving in neutral or on inclines.

Solutions and repair options include :

• Replacing the lambda sensor to correct air-fuel mix problems, clear engine warnings, and smooth engine operation. Professional diagnostics recommended before replacing.
• Inspecting and securing exhaust mounts, silencers, and pipes to fix vibrations or knocking sounds.
• Cleaning or unblocking the exhaust line especially after short cold-weather trips.

For best results, always consult a qualified mechanic to verify fault codes and perform repairs.
