Hi, I have a 52plate 406hdi, 160k. The car sounds fine and the turbo whistles nicely, but after a good warm up, when the engine's idling, sometimes it 'blips'. It idles at 800rpm but will flip up to 1000 and back again. This happened earlier in the year and I put a turbo cleaner through it and it seemed to help. It started again this week and i'm paranoid the turbo will blow as it did on my last 406.
Has anyone experienced this problem before, if so, is there a problem, is there a solution?
Thanks
