Problems with Peugeot 508 model year 2016: Engine problems, loss of power and exhaust odor

Hi, I once had a similar problem with my 2014 Peugeot 508. I have experience with cars with a low level of understanding. As soon as the 'Check Engine' indicator light came on, I took the car to my regular garage. After a few tests, it was identified that the engine control unit was faulty, costing around 1000 euros to replace and repair. Before jumping into expensive repairs, check the simple things first, such as the air filter and spark plugs. Reading out the fault memory might also help to narrow down the problem. Could you give me more information about your vehicle, for example the current mileage and whether repairs have already been carried out? It may help to give further tips and understand the problem better. Hope this helps!

Hey, thanks for the advice, that helps me a lot. My Peugeot has done 168024 kilometers so far. It was last checked and repaired in the garage some time ago, but there were no major abnormalities. I will follow your advice and check the simple things like the air filter and the spark plugs and of course try to read out the fault memory. Hopefully I can get to the root of the problem that way. Thanks again for your help!

Hey, no problem, always happy to help! With the mileage, it could be that some parts are showing wear. A good idea is to check the fuel filter and system. If it's clogged, it can cause combustion misfires because the engine isn't getting enough fuel. It is usually changed every 50,000-100,000 kilometers, but of course it always depends on the driving style and the fuel quality used. Another point would be the lambda sensor, which is responsible for regulating the air-fuel mixture and can also be responsible for uneven engine running and high exhaust emissions. It is best to seek professional assistance from a workshop if you cannot find the fault yourself. This may be more expensive, but it can help you to avoid major damage and the associated costs. I hope you find the cause soon and get your Peugeot running again!

Hey, thanks again for the tips! Your experience is really helpful. I will have the fuel filter and system checked, as well as the lambda sensor. You're right, I don't want to damage anything, so I'll take my car to a garage if I can't find the fault myself. Hopefully I can solve the problem as soon as possible and get back to driving without any worries. Thanks for your support!
