1.6 HDI underpowered and turbo noise

Post by cch0223 »

Hi, this is my first post. On my way back home my Berlingo suddenly is underpowered and the engine bay is much louder. Although the sound seems like it's coming from the turbo and the turbo shaft has quite a bit of play, and the blades have seen some damage, I don't see a fault code for it. I found a leaking injector and I cleaned it, the same. There was a fault P1461 then I replaced the egr, still the same. So I got myself Diagbox, and P1461 did clear but can't see why it's making the noise. Is a turbo replacement unavoidable? Here's some video and live data, any help is appreciated.

Fault code present: F5FF, C98B, C98F, F905
Live data when the engine running:

I agree, I don't think these fault codes are going to help after watching that video....

Thanks everyone! I couldn't take off the undertray to fix it so I eventually sent it to the mechanic. it's indeed a bad turbo and that's £750 for the job. From what I have googled I thought it would be like £1300, but still, it's a lot of money
