As far as I know there is only one Dutch audiobook in the SAS-series. It's called 'Het spoor naar Brazzaville' and was published in 1993..

Published by Interval in a series called Bandelier (INTMC-40-MI 2; ISBN 9055290491. Read by Kees Scholten.
In the early days audio-books were made for blind people or people with a reading disability. Now these books are also made for people who like to hear them 'on the road' listening to their cd- or mp3-player.

The original audiobook is no longer available. It was published on audio-cassettes.

You can download them right here as mp3:
