Peugeot Boxer Exhaust Leak
Summary of the thread
A 2005 Peugeot Boxer with a gasoline engine is experiencing a check engine light, loss of power, and increased fuel consumption. The issue may be related to the exhaust system, potentially a leak affecting the exhaust temperature sensor. This can cause incorrect sensor readings, leading to poor engine management and increased fuel usage. The recommended solution is to have the exhaust system professionally repaired to ensure proper sealing and restore vehicle performance.

Thanks for the quick reply! I'll definitely check for soot. If it is a leak, is it something I could patch up myself, or am I better off taking it to a shop? And would that explain the increased fuel consumption too?

Patching it might work temporarily, but it’s best to get it properly welded or replace the faulty exhaust component to ensure it seals correctly. A leak throws off the O2 sensor readings, messing with the engine management and causing it to overfuel. I would take it to a workshop.

Thanks a bunch for the advice! I took it to the shop, and you were spot on – it was a leak in the exhaust system causing the temperature sensor to go haywire. The repair cost me about 265€, but at least it's running smoothly now! I really appreciate the help!

Sounds like a faulty exhaust temperature sensor. Is your Boxer's exhaust system making any unusual noises? A leak can mess with the sensor readings and cause those symptoms. Check for soot around joints in the exhaust system; it's a telltale sign.
