Saxo Exhaust Leak

I'm experiencing an issue with my 2002 Citroen Saxo, gasoline engine. The check engine light is on, and the engine runs roughly. There's also a noticeable exhaust leak and strong exhaust smell. It has 230754 km. I suspect an exhaust treatment malfunction but am unsure of the cause.

A 2002 Citroen Saxo is experiencing a rough-running engine, a check engine light, and a noticeable exhaust leak with a strong smell. The suspected cause is an exhaust treatment malfunction, potentially due to a faulty lambda sensor. It is advised to have the vehicle diagnosed at a workshop to confirm the issue and avoid unnecessary part replacements.

Hey there! Exhaust leaks are nasty. I had something similar happen with my Saxo, though I can't remember the exact year. Check if it smells strongly of unburnt fuel; mine did. The rough running and the light are classic symptoms. Could be the lambda sensor packing it in. Worth a look!

Thanks for the suggestion. When your Saxo had similar symptoms, were there any other indicators or noises accompanying the exhaust leak? Did you also see a decrease in fuel efficiency?

Yeah, fuel economy went down the drain, and it was louder than usual, like a constant hissing on top of the engine noise. Honestly, I didn't dig too deep myself. Took it straight to a workshop. They hooked it up to a diagnostic thingy and said it was the lambda sensor. Best to get it checked properly before you start replacing parts.

I appreciate you sharing your experience. Based on your insights, I will schedule an appointment with a workshop to diagnose the issue thoroughly. I'll let you know the resolution once the problem has been identified and addressed. The final repair cost was 375€ with the defective lambda sensor replaced.
