Turbo assistance
Posted: Wed Sep 17, 2025 9:30 am
Greetings, everyone,
I own a 2008 Bluetek with 200,000 miles that has been underperforming and need help. The Check Engine Light (CEL) remains on, and the vehicle is entering limp mode. After recycling the key, the vehicle operates properly for some miles until issues reoccur. I had many codes, including a downstream O2 sensor (which I replaced), a 2598-001 EGR positioner fault (which I fixed), and a 2944-004 Glow plug 3 (which I have not yet replaced). Upon replacing the EGR, I began receiving the error code 2355-001, indicating that the EGR air mass is insufficient. Although it no longer enters limp mode, it began to exhibit jerking during acceleration virtually every time I started it, but seemed to settle after operating for a period. The engine's RPMs corresponded with the jerking motion. The fuel efficiency is poor at 20 miles per gallon.
This prompted my suspicion of intake manifold obstruction and swirl flaps.
Yesterday, I removed the intakes for cleaning, as well as to repair the oil cooler and swirl motor, and began to contemplate the acceptability of the turbo. There is no indication of the vanes contacting the edges of the housing, and there is little movement when I try to shift the vanes laterally. Upon acquiring the vehicle, the owner informed me that the Turbo had just been changed, however there is no definitive means to verify this claim. I will begin the clean-up procedure on the intakes, but I would want to gather opinions about the potential malfunction of the turbocharger. I prefer to replace it now rather than in a month, despite the expense of $1300. One of the exhaust nuts on the Turbo fractured during removal. If I retain this one, I must have an extraction.
What are your opinions? Thank you so much!

I had to stop the vehicle to deactivate and reactivate it. The vehicle exhibits this behavior when I accelerate fully to overtake another automobile, resulting in a complete lack of acceleration thereafter. No check engine light or any issues so far. It is hoped that the technician would promptly identify the problem.
