Hi,
a broken DME relay is one of the most common failures of the Porsche 944. The video shows how to check the relay. In most cases a broken soldering point in the relay is the reason for the male function. The video gives you a tutorial how to solve the problem:

The video has a German soundtrack, but English subtitles are added to YouTube. If you don't see the titles by default, watch the video directly at YouTube and press on the subtitles button below the frame.
Enjoy it,
Jürgen
