Problems with Peugeot 108 Diesel: Black smoke, high fuel consumption and suspected defect in the lambda probe heater

Hello, I once had a similar problem with my Peugeot 106 petrol engine, year of manufacture 2018. I'm not an expert, but I have some experience with cars. Had the same symptoms and it turned out that the engine control unit was broken. I had it replaced in an independent workshop and it cost me a whopping 1000 euros. I would recommend that you have it checked at a garage. Please give me a little more information about your car, maybe I can then help you more specifically. I hope this helps you a little!

Thanks for the quick reply! I have an appointment at the garage next week anyway. I was worried because my car already has 150,722 km on it. Of course, it would be great if it was just the engine control unit. But I also suspected a defective turbocharger, as the car is also losing power. Hopefully it won't be too expensive. In any case, I'm looking forward to hearing what the garage has to say. Thanks again!

Hey, no problem! You try to help where you can, right? Your suspicion about the turbocharger could well be justified. My Peugeot had a faulty one and the symptoms were very similar to what you describe. Unfortunately, it's not cheap fun, a new turbocharger can cost quite a bit. The best thing to do is to tell your garage to take a closer look at the turbocharger. There's obviously something wrong with the combustion if black smoke is coming out of the exhaust. Keep your fingers crossed that it won't be too expensive. Keep us up to date!

Many thanks for the advice! I will definitely take your tip on board and tell the garage about my suspicions regarding the turbocharger. Hopefully the repair costs won't be too high. I'll definitely keep you posted and report what the cause was. Thanks again for your help!
