Hello all,
I have a 300Tdi 110 CSW that is currently on ~90k and went for a service recently. There were no strange noises from the turbo prior to the service (having just covered 1000 miles the week before) and as usual was pulling like a train up big hills. The only thing of note was a vibration which appeared quickly and was traced down to a worn / broken UJ (subsequently fixed in the service).
When I picked it up from the service the turbo whine was a little louder than normal but nothing excessive. After ~100 miles I was on the way to a shoot and there was a clunk which I thought was a bolt or something from the road (still could have been). A mile or two down the road there was a "twang" followed by a loss in power on the way up a short but sharp hill.
I limped to the shoot which was just down the road and before returning home checked through the pipework - there was no oil in the pipes and none looked de-laminated, thinking it might be the wastegate stuck shut (and not knowing where it was at the time) I drove home slowly on back roads at more or less a tick-over trying not to spin up the turbo too much.
When I got back home I had a more thorough look and with a mirror subsequently found the damage in the attached picture.
Now the question is - that ring of metal that looks like it caused all the damage - is that a foreign object or part of the turbo itself?
