Problems with Peugeot 607: Black smoke, engine problems and high fuel consumption - looking for tips and experiences

Hey buddy, I drive a 2004 Peugeot 605 gasoline, so a very similar model. I'm not a professional, but I have some experience with cars. I had a similar problem and suspected that the fuel level sensor was spinning. My garage helped me. In my case it was a faulty wiring harness/plug. The problem was solved by replacing the defective plug. That cost me 95 euros. Could you give me more details about your vehicle? Maybe I can help you better that way.

Thanks for the answer, buddy. My Peugeot now has 81528 KM on the clock. I took it to the garage last time about 6 months ago. I will take your advice and get the wiring harness/plug checked. I just hope it's nothing major.

No problem, always welcome! Given the mileage, it could well be that you simply need to replace a few wearing parts. The wiring harness/plug is definitely a good place to start checking. But it could also be the lambda sensor, especially if your Peugeot has a high fuel consumption. It may cost a bit more, but it's still within reason. I hope it's nothing more serious. Keep us posted, buddy. Good luck!

Thanks for the insight, I will certainly come back for an update. Well then, off to the garage, I hope it's nothing serious. I'll take your tips on board and have both the wiring harness/plug and the lambda sensor checked. Thanks again and see you around!

Hi, I'm getting this kind of message even though I don't have any fuel sensor problems, and even less so with a 607.
