There is a possibility it is not the turbo and simply a bad connection between the turbo outlet and I guess your downpipe.
When it happened to me, it occurred immediately after work on my clutch. The dealership identified it as a leakage between the turbo exhaust outlet and the dpf unit on the side closest to the turbo.
They contacted BMW/Mini and headquarters in Munich recommended they change the turbo due to risk of internal failure of a turbo seal.
Since then, I have had no soot buildup, but I notice the car has slightly reduced power. The new turbo will be 1 year old in January 2013.
If under 1 year, it should be replaced/fixed (depending on the problem) at no cost to you assuming the work to change the turbo was carried out by the dealership. I don't know what the dealer will say concerning the dpf delete if that was not done at the dealership.
Had a call late this afternoon the issue is the way the dpf joins to the turbo it isn't fully aligned so need to have the front end off to fully align and then the pipe from the airbox to the turbo needs to be replaced
All in its best part of £500 so hopefully it is perfect when I get it back and runs just right.
All this just after the dpf delete its been an expensive 2 weeks
Hmmm am reading all these posts about turbo lag, it is a very frustrating issue this. I have today changed the orange seal (small split), check movement in the turbo nothing then cleaned the maf sensor, ours does have a tuning box but even that doesn't help it. I think the next step is the crankcase sensor replacement, after that who knows !!!!
:-/. Good luck with your recent fix ;-)
Hmm I saw exactly where the crankcase sensor sits so its not a difficult job, I will also try unplugging the maf in ours and see, could be the same fault :-/ I do hope not cause they cost a small fortune :-(((((
