Yes, that is true. The gasoline turbo Audi 5000 cars sold in North
America starting with the 1984 model year all do have the extra flywheel
timing sensors, according to the Audi Factory Service info I just looked
at. Up to 83 models do not and none of the non-turbo 5000 models have
them in the 1979-1988 5000 models my manuals covered.

The original post was regarding a 1986 5000CS, which has the extra
timing sensors.
