VW Golf Diesel, 2008 - possible defect in boost pressure sensor?

Hello, I have a strange problem with my VW Golf Diesel, built in 2008. It smokes black from the exhaust when accelerating, the check engine light is on, the engine power is reduced, it jerks when accelerating and makes a loud hissing noise. In addition, the fuel consumption is high, the exhaust smells strongly and there is a whistling noise. I think it could be the boost pressure sensor, but I'm not sure. Has anyone had similar experiences and can give me some tips on how they solved the problem in the workshop? I would appreciate your experiences and tips.

A 2008 VW Golf Diesel is experiencing black smoke from the exhaust, reduced engine power, jerking during acceleration, loud hissing, high fuel consumption, and a strong exhaust smell. The owner suspects a defect in the boost pressure sensor. A similar case suggested that a clogged Diesel Particulate Filter (DPF) could be the cause, and recommended checking and possibly cleaning or replacing the DPF. Reading the fault memory is advised to confirm the issue, which may also indicate a problem with the boost pressure sensor.

Hi, I had a similar problem with my 2006 VW Golf Diesel, I would class myself as someone with some experience in car repairs. When I went to my garage they said that the bottom DPF was clogged. It cost 1325 euros to fix the problem. Can you please give me more information about the car? That would help me to help you in more detail.

Hello, thanks for the quick reply. Well, my Golf Diesel is also from 2008 and already has quite a lot on it, namely 221790 km. The last service was recently. I think I'll have to take it to the garage and have it checked. Your experience will definitely help me, thank you!

Hello again, the car with so many kilometers has certainly seen a bit of action! Your Golf is two years newer than mine, but the symptoms are exactly the same. It could well be that your DPF is also clogged. In any case, there's no way around having it checked and then cleaned or replaced. It may cost a little, but afterwards your Golf will run like new again. Don't forget to have the fault memory read out. The boost pressure sensor may also be indicated as the source of the fault. Good luck, buddy!

Hello, thanks for all the tips and suggestions. Maybe you're right and it's the DPF. Reading out the fault memory is definitely a good idea, I'll have that done straight away. I just hope that the bill won't be too expensive! But what don't you do for your car, right? Good luck with your Golf and thanks again for the help!
