It's safe to drive. You will occasionally get some black smoke.

Your variable geometry may be stuck or you may have some problems with the turbo arm.
Get the car on a ramp and see if the turbo arm/variable geometry is moving easily.

See below, a picture taken from under my car, red arrow pointing turbo's arm that drives/moves the variable geometry.

So, the car started to make a very loud 'farting' or grating noise when I got it to kick down or accelerate hard. Revving it at standstill produced a whistle that had not been there before. I read this thread and decided it might be one of the larger turbo pipes spilt, but I wasn't losing performance or getting faults. I called round to my mechanic and we put it on the ramp. Broken Clip holding the turbo onto the exhaust. £30plus quid for the clip!! and probably half an hour labour but it has cured the problem. FL2 SD4 HSE lux auto
