Nemo Jerking Whistling Noise

I've got a 2011 Citroen Nemo, gasoline engine, with a bit of a headache. The check engine light keeps popping on and off at 245998 km. When I accelerate, it feels like it's jerking around, and there's this whistling noise, almost like a loud hissing, especially when I put my foot down. Sometimes, when I stop, the engine just stalls out. Fuel consumption has definitely gone up, and the power just isn't there anymore. I was reading online, and it sounds like it might be the boost pressure sensor? Could be a faulty cable or plug connection, maybe? Anyone else had something similar?

Sounds familiar. I had similar issues with my Nemo. Check engine light, jerking, the works. Is it worse when the engine is cold?

Yeah, it does seem worse when it's cold. Like, really sluggish and jerky until it warms up a bit. What was the issue with yours, and how did you fix it?

Yep, sounds like the same thing. Turned out to be a bad boost pressure sensor, like you suspected. Honestly, I'd take it to a workshop to get it checked out. Safer than messing around with it yourself if you're not sure.

Right, I appreciate the advice. I booked it into a workshop and you were spot on. Turns out it was the boost pressure sensor and a dodgy connection, costing 95€ to sort. Thanks again!
