Peugeot 206 running rich power loss

Hi, I've got a 2005 Peugeot 206, diesel engine, that's giving me a real headache. It feels like it's running way too rich, like it's getting too much fuel. I've noticed a definite drop in power, and the check engine light has come on. The engine runs rough, and my fuel consumption has gone through the roof! Also, it feels like the car is jerking when I'm accelerating. It has 112809 km on the clock. I've checked the air filter, but it looks OK. Any ideas what could be causing this?

A 2005 Peugeot 206 with a diesel engine was experiencing issues such as running rich, power loss, rough engine performance, increased fuel consumption, and a check engine light. The problem was suspected to be related to the fuel injectors. After professional inspection and replacement of the defective injectors, the car's performance returned to normal.

Sounds like a fuel injection problem. When was the last time you checked your spark plugs? A rich mixture combined with those symptoms definitely points towards the injectors. Has the car been sitting for a long time?

Thanks for the quick reply. The spark plugs were changed about 20,000 km ago. It's my everyday car, so it hasn't been sitting unused. Could a faulty injection valve really cause all these problems?

A defective injector valve can indeed cause those issues. Too much fuel entering the cylinders will lead to incomplete combustion, hence the rough running, reduced power, increased fuel consumption, and the check engine light. I'd advise getting the injectors checked professionally at a workshop.

Thanks a lot for your advice! I took the car to the workshop, and they confirmed that the fuel injectors were defective and replaced them. The repair cost 515€. Now the car is running perfectly again!
