Hello Maybe someone had a similar problem before, but I haven’t found a suitable thread so far… In my 850er (Bj. early 1995, still with OBD I Diagnosis box) during the highway ride all the pointer instruments of the speedometer / combination instrument at once failed or all pointers (windiness indicator, tank indicator, temperature indicator, rev indicator) “fall” to zero position and still show no reaction, not even a twitch when switching on the ignition. The total and day-kilometre display has also stopped at this time… The car runs without problems, all light symbols in the lower range work and run out after starting – only the warning arrow of the automatic transmission flashes due to the lack of speed signal. I have turned out the error codes, the set errors show nothing further except the mentioned missing speed signal – but: the interesting error memory of the beech A7 from the instrument cluster shows no feedback – not even the 1-1-1 comes back … no reaction/blinkcode, contacting I tried several times, the pin is well in the socket – maybe there is also a connection here ? If the instrument cluster or its board is possibly dead, then nothing arrives at the OBD anymore ? The speedometer lighting works by the way – its fuse is also intact … a separate protection of the display (a I don’t seem to have the 4 pointer instruments) as far as I have taken this from the descriptions of the fuses at first sight. I have not yet expanded the speedometer unit, in the hope of pointing out a perhaps simpler problem… Maybe someone has an idea. Thank you in advance!
