Citroen C3 Jerking Acceleration
Summary of the thread
A 2015 Citroen C3 diesel was experiencing jerking during acceleration, a check engine light, a whistling noise, engine stalling at idle, and reduced power, leading to suspicions of a bad boost pressure sensor or defective connections. The issue was identified as a defective boost pressure sensor cable. Repairing the cable resolved the problems, restoring the car's performance.

The whistling noise is mostly under acceleration, not constant. I will definitely check all the hoses. If the hoses are fine, is there anything else that could be causing these issues with the boost pressure sensor?

If the hoses look okay, the sensor itself could be faulty, or the wiring to it. Honestly, it's probably best to take it to a workshop and have them diagnose it properly. Could save you money in the long run.

Thanks for the advice! I took it to a shop, and you were right – the boost pressure sensor cable was defective. Cost me 95€ to repair. Runs like new now!

Sounds like a boost leak for sure. Check the hoses going to and from the turbo, and make sure they are all securely connected. Is the whistling noise constant, or only under acceleration?
