Has anyone swapped out a turbo?

@NQ94 Thank you. Have you used Google Translate? If not, here it is, 100% Englisch: https://matsch--und--piste-de.trans..._sl=de&_x_tr_tl=en&_x_tr_hl=de&_x_tr_pto=wapp

However, what I read in your post seems still to point to external factors killing the turbo.

The VTG is in deed something you can easily check and you should do it. Just run the engine, accelerate and deccelerate and check if the rod and the VTG is moving freely.

If that got stuck while open, ok, less power. But if it got stuck closed, you'll end up with an turbo overspeeding damage. The compressor blade wheel will expand and grind at the housing and at some point it might break apart.

Easy to detect afterwards. Check the back of the blade wheel. If it shows a lot of small dents it suffered from overspeeding.

True for the older style with a boost control solenoid. The more advanced with a little motor and a gearbox controlled by the ECU are somewhat harder to diagnose.

My Td4 has a turbo ECU and it is easy to check. I do not check all possible positions, but if it moves freely. That's enough. However, I had to exchange the ECU already once, as I noticed that the VTG didn't move at all, anymore. No big deal.

Thanks, used translate but possibly printing at work didn't help.
