Problems with Peugeot Boxer 2020: Black smoke, high fuel consumption and possible defect in the fuel pressure regulator

Hey guys, I have a problem with my 2020 Peugeot Boxer with diesel engine. When accelerating, black smoke comes out of the exhaust and the engine light is on. The engine shuts off by itself, has loss of power, runs rough, jerks when accelerating and the fuel consumption is quite high. There is also a strong smell coming from the exhaust and it dies when idling. I think the fault lies with the fuel pressure regulator. Have any of you ever had a similar problem? How did you have it solved in the workshop and what was your experience? Thanks in advance for your tips!

Hi, I had a similar problem with my Peugeot Expert 2018. I have little experience with cars but went to the garage because I wasn't sure how to fix the problem. They found the fault entry after changing the fuel filter and fixed it. This cost me 45 euros. Can you perhaps give me more information about your vehicle, such as the engine power, mileage or whether the vehicle has been regularly serviced? More details about your vehicle would help me to be more specific about your specific problem. Hope this was helpful for you!

Hi, thanks for the info! My Peugeot currently has 103233 KM on it. Unfortunately, the last inspection was some time ago. How did you find out back then that the fuel filter was the problem? Do you think that could also be the case for me? And will the insurance pay for it? Thanks again for your time.

Hey, I'm glad my post was helpful. In my case, the fuel filter was clogged with dirt and dust particles, which can cause these symptoms. The garage carried out a diagnosis and fixed the problem within a few hours. As to your question as to whether this could also be the cause in your case: Difficult to say without taking a look at your car. But based on your description - especially the high fuel consumption and the black smoke - it could indicate that the fuel filter is clogged. Unfortunately, I can't tell you whether the insurance will cover this, as it depends on your insurance contract. But as a rule, maintenance and repair of the fuel system (including the filter) is part of the normal maintenance costs borne by the owner. I would definitely recommend that you take it to the garage and have it checked, as problems like this can become more expensive if they are not fixed. Good luck and I hope your problem is solved soon!

Hello, your answer has helped me! Indeed, I had no idea that the fuel filter could cause so much trouble. Well, I guess I will have to make an appointment with the mechanic to check it out after all. Find it a bit annoying as I don't have it that thick. But I guess it's better to spend a bit of money now than a fortune on major repairs later. Thanks again for your advice and detailed explanations. It really helped a lot and I appreciate it. Take good care of yourself!
