Mine was suffering from from low boost pressure about 3 weeks ago on the reader, kept showing engine management light and reduced performance bought some turbo cleaner from Halfords £9 and put in diesel tank, running loads better and no problems since, worth a try. Mines going to have a dose every 6 months now.

I just posted my story on another thread but it would equally fit here. I had the same symptoms, which got worse to the point that I was ready to scrap it. Changed the fuel filter but still had the problem. Smokey black exhaust on hard acceleration too. Tried Wynn’s Turbo Cleaner fuel additive (not the system or injector versions). Mine was so bad it took 2 treatments to fix it but it is now sweet as a nut. Total cost about £15! No more smoke and no more limp mode.
