Hi did you sort out the noise problem? as my fabia has started doing the exact same thing and i cannot get to the bottom of it.

The 110 and I think the 130 have VVT (variable vane) turbos which can get sticky vanes on the exhaust side - this can cause a overboost to occur and the car to go into limp home mode (power cycling the ignition cures the limp-home mode). The solution seems to be to clean the turbo up, although this is not a job everyone fancies doing. I think it is about 90 mins work to get it off / refit, to you would be looking at 3 hours before the clean up process takes place.
