Peugeot 807 Jerking Loss of Power

Hi, I'm having trouble with my 2002 Peugeot 807 diesel. It's got about 290k km on the clock. Recently, it's started jerking when I accelerate, the check engine light is on, and there's a noticeable loss of power. It also sometimes stalls at idle and runs really rough. Plus, there's a strong exhaust smell. Any ideas?

Sounds like you might have a manifold pressure issue. Is there an error code stored? It could be related to the intake manifold or the manifold sensor. Check for any obvious leaks or damage around the intake area. What does the error memory say?

Thanks for the quick reply! How exactly do I check for leaks around the intake manifold? Is there anything specific I should be looking for? I don't have much experience with this sort of thing.

Okay, without seeing it, it's tough to say for sure, but scorching and leaks around the intake manifold on those engines is a known issue. It can cause all the symptoms you describe. Honestly, with those symptoms and the mileage, you're probably best off getting it checked by a workshop. I suspect you need a new intake manifold.

Thanks, I appreciate the advice! Took it to a mechanic, and you were right. The intake manifold was leaking due to scorching. Cost me 1180€ for the repair. Runs like new again!
