Hi,
the series continues. The video
http://www.youtube.com/watch?v=fnJbA2CEsbA
shows how to read out the error memory of a VW Climatronic. In my case the relais of the air blower made problems, which have been solved by soldering the relais.
The video has a German soundtrack, but English subtitles has been added to YouTube. Look out for the cc-button under the video.
Best regards,
Jürgen
