Peugeot 207 boost pressure sensor issue

I'm having trouble with my 2014 Peugeot 207 diesel. It has 66586 km. I think it's the boost pressure sensor. The check engine light comes on and off, it jerks when I accelerate, there's a whistling noise, and a loud hissing sound when accelerating. Sometimes it stalls at idle, fuel consumption is up, and it feels like it has less power. I think it might be a bad cable or plug connection to the boost pressure sensor. Any ideas?

Sounds familiar! I had almost the exact same symptoms with my old Opel Astra. Check engine light, weird noises, the whole shebang. I'd put money on it being something to do with the turbo system. Was a pain to diagnose!

Could you tell me more about what happened with your Opel Astra? Did it also involve the boost pressure sensor or something else in the turbo system?

Yeah, it turned out to be a faulty boost pressure sensor, just like you suspect. Honestly, it's probably best to get it checked out at a workshop. They'll have the right tools to properly diagnose it and make sure everything is working correctly.

I took it to a workshop, and they said it was a defective boost pressure sensor because of a bad electrical connection. The replacement and labor cost 95€. It fixed the problem, and it's running like normal now. Thanks for the help.
