I had the unit repaired now at one of the very few still existing electronic
repair shops in a city of 1,6 millions for a reasonably price. The guy said it
was quite a job to clean and resolder the indicated connections but it seems to
be ok now. After installing it and turning on the ignition, the ABS- and
TRACS-lights went out quite quickly. After dysfunction before the repair often
the lights stayed on until having driven about 10-20 meters, first then they
went out. Tempomat and speedometer work. I have not hat a chance to test the
ABS-function here in the city but will test tomorrow in the countryside on a
gravel road but if the unit survived my soldering work last year, it must have
survived the work of a craftsman. If that works I will take it out and seal the
surface of the circuit and the box. I was not successful to find definitely
acetateless clear high temperature silicone so I will use a spray sold in an
electronics market meant to cover circuits with a film against moistness etc.
For sealing the lid I have something appropriate. Hopefully this will be the
last work on the unit for ever!!
