Code 66 is the dread of all Twin-turbo B4's. It is a reasonably generic code
that means there is something wrong with the Twin turbo System. Is the boost
consistent when reached? During change over from primary to twin is there a
drop in boost or a wavering? The boost solenoid could give you more of a
hint to the real problem.

All the manual says is code 66 - Twin Turbo System. Doh!!!

I have uploaded to the files section a 3 page 'diagnosis guide' for this
particular error. Hope this helps. Sorry I am not technical enough to help
further. Just a good keeper of stuff. :-)
