Turbo trouble
Had the problem of the car going into limp mode since i bought it.
Diagnosed as sticking vnt. Bought another one from a breakers and had it fitted this week. This one whines constantly so i guess it's also a dud. What i don't understand is the whine is present with foot off the accelerator ie coasting . As far as i can tell there are no air leaks , and there is no limp mode. Pulls well if I'm honest. The original I'm planning to exchange at aet turbos chester , any experience of them? Cheers

Why not clean the original?
Here is a step-by-step tutorial. It's not that difficult.

Appreciate what you're saying but one turbo whines and the other doesn't on the same set up.

The whine is VERY noticeable while just revving.

The only difference is the turbo , as for play , they were roughly the same.

I never liked the wine when I had a new engine (+ turbo) fitted.
Do you have a lack of power at low revs by any chance with the 'new' turbo? |
